DIY Appliance Repair: Clothes Dryers

640 505 Thomas

You might think dryers are simple and you’re right. But they do break. Most times it’s not serious but still a big inconvenience. Wouldn’t it be nice if you could diagnose a dryer problem in five minutes flat? After reading today’s edition in the DIY Appliance Repair Series about dryers, you will have a better understanding of what they do, how they do it, and a few simple solutions to some common problems.

Here’s what I’ll be talking about today:

  • How dryers work
  • Common problems you can fix
  • When not to try
  • It’s time to contact Tin Lizzee for help

So, how do dryers work?

They’re not scientific marvels. Not even close. They have a drum for your clothes and a drive belt driven by an electric motor. When the drum turns, heat is produced by the heater (electric or gas) and assuming it has a clear vent, begins its mundane task of drying your clothes.

The genius part of dryers is how easy they perform its task of drying clothes. You may remember drying clothes on a clothesline before dryers came along. Speaking of clotheslines, the process represents what happens in your dryer today.

Illustration of laundry hanging from clothesline.All dryers require three things to happen in harmony with each other. First, we need heat (sun) to dry clothes. Heat by itself cannot dry clothes. It can only heat them. Airflow (wind) mixed with heat dries clothes. Good airflow dries them faster and better.  So, you see, we need heat and airflow to dry clothes.

The third thing all dryers need is a way to tumble clothes to allow hot, moist air to escape through the clear vent to facilitate drying. In a clothesline scenario, clothes suspended in mid-air and wind gently blowing around them replicates tumbling.

Dryers replicate the clothesline process well. However, if any of the three elements of drying are missing, efficient drying can’t happen. That said, let’s look at what you can do quickly to remediate a drying problem.

Common, easy to fix dryer problems

  1. I’m sure you’re familiar with long dry times, but have you learned what causes it and better yet, how to fix it? When you notice towels taking 80-90 minutes or more to dry, something is up.

The first place to check is outside where the vent exits your house. Inspect it. Is it clogged? My guess is yes. Remove the screen if needed and reach inside to remove packed in lint but watch for a nest! Birds and other animals like the seclusion and warmth of a dryer vent. Wear gloves for this!

If it was clogged and now it’s clean, run your dryer empty for about 5 minutes to remove any loose lint. If you’re satisfied that everything is OK, put the screen back in, and you’re good to go.

TIP: Some people opt to leave the screen out and get in the habit of checking the now open vent regularly. If your vent has louvers, leave them in for protection.

What I just shared with you could save you big time in charges for vent cleaning and higher bills for the extra run time of the dryer!

  1. If your vent is clear and you’re still experiencing long dry times, look at the vent from your dryer to the wall. Is it crushed or kinked? Crushed or kinked vents are a leading cause of long dry times, eventually leading to excess lint buildup inside the dryer, increasing the chance of a dryer fire.

The simple fix for this is a new vent. Lowe’s, Home Depot, or any other hardware store sells them. Remember to use only metal vent. Refuse vinyl if you see it. It’s dangerous to use and banned in most states.

  1. If I had a nickel for every time I found the next simple problem and fixed it in under 2 minutes, I would be on easy street. Can you guess what it is? If you guessed to check the breaker, you’re right!

It happens this problem occurs far more often with electric versus gas dryers. If an electric dryer is missing half of its required 220 Vac, it runs but won’t heat. Many times, checking and resetting the breaker fixes it. Try resetting it a few times. Another simple fix!

When Not to Try

If dry times haven’t improved after cleaning the vent to the outside and replacing the section from the dryer to the wall, a mechanical problem such as a stripped blower wheel might be the culprit. It doesn’t happen often but enough to talk about it.

A stripped blower wheel is one repair that isn’t a simple fix. In fact, if you’re not trained to repair this, do not try it. You’ll discover you’re in too deep once you have the dryer torn apart. For this repair, it’s time to reach out to us and let us guide you through every step.

It’s time to contact Tin Lizzee for help when…

  1. Your dryer has no power.
  1. It powers on but won’t start.
  1. It’s very noisy when running.
  1. It runs but doesn’t heat (for electric dryers, check your breaker first!)
  1. It runs but doesn’t heat (for gas dryers, the flame goes out quickly)

DIY Appliance Repair: Dishwashers

640 427 Thomas

Think of it – relaxing after a nice dinner, talking about the day, and enjoying some well-deserved down time. Sounds great, doesn’t it? What if your dishwasher wasn’t working and you, your wife, and the kids couldn’t relax just yet because the dishes need to get done?

Surprisingly, we can trace most dishwasher issues back to the operator (that’s you). But what you probably don’t know is they’re easy to solve when you understand how they work and how to make them run their best. See, it’s not you, it’s only because you weren’t trained well.

That’s what I’ll be discussing here. Welcome to the dishwasher edition in our Getting Started Series presented by none other than our favorite group of DIY Online Appliance aficionados known as Tin Lizzee!

What will you learn today?

  • I’ll describe typical dishwasher operation such as what happens when you close the door and press START.
  • How to troubleshoot and solve two common “washability” issues.
  • When you should contact Tin Lizzee for a helping hand.

Basic Washing Operation

Dishwashers clean dishes much like a touchless car wash. It uses high pressure water mixed with a special soap designed to clean dishes. After washing, rinsing occurs followed by a drying cycle to finish.

You may wonder why dishes take forever to clean. Lots of things happen internal to the dishwasher causing wash times to vary. Water temperature sensors and turbidity sensors (water clarity) affect wash times.

If your dishwasher uses a digital display, the time shown is an estimate and varies or appears to get stuck and not move. More about this in the Washability Section.

As water gets pumped into the dishwasher, the upper and lower spray arms move and spray water on the dishes. If your dishwasher offers options such as upper rack only, or turbo wash, pressure changes from upper only to lower (turbo) only, depending on the option chosen.

Rinsing

Before rinsing, the dishwasher drains and brings in fresh water and starts a similar wash-like action without soap. It’s during this cycle the dispenser pulses its solenoid and releases a measured amount of Rinse Aid into the rinse water.

Some people refuse to use Rinse Aid, but it’s designed to increase overall washing performance. It helps water drain in sheets from dishes, reducing water spots and help dry, too. Using Rinse Aid or any other rinse agent is your choice but knowing how well it works might change your mind.

Drying

Picture of modern dishwasher with door open slightlyAfter the final rinse, the heater turns on and starts its drying cycle. If you prefer to air dry the dishes, crack the door after the final rinse, or select the option for air dry. Most dishwashers use an exposed heating element for drying. It’s located inside on the bottom and gets very hot. Don’t touch it!

Some newer dishwashers offer air dry only, so watch for this when shopping for a new unit.

Others use a combination of forced air through a heated chamber on the bottom of the sump assembly inside, near the lower spray arm. Heads up – this option doesn’t perform well.

Washability Issues

  1. Takes too long to wash. One of the more common complaints we receive is the dishwasher washes for three or more hours and dishes aren’t clean. Three hours is about the limit for any dishwasher working normally in extended cycles such as sanitize or sensor wash.

Solution: Aside from a normal three-hour cycle, the turbidity sensor or main control usually is the blame for this. We define turbidity as the clearness of the water. If the dishwasher is dirty from prolonged use, food particles build up in the sump and mix with fresh water used for washing and rinsing.

As wash water passes through a turbidity sensor, it can shorten a cycle too much, or cause extended cycles over three or more hours. If the sensor fails, either can happen with dirty dishes as a result.

When a working sensor detects dirty, cloudy water, it directs the dishwasher to pause its wash cycle, drain, and bring in fresh water to help clean the wash water. The function adds significant time to the cycle.

You’ll notice something isn’t right when the display seems to get stuck on say, 2.5 hours or 150 minutes and doesn’t move – ever. Suspect a failed turbidity sensor or main control. If so, contact us for an appointment to walk you through the repair.

TIP: Use dishwasher cleaner monthly to keep it running its best (i.e. Dishwasher Magic by Glisten).

  1. Dishes don’t dry. Believe it or not, dishwasher heaters rarely fail today. Not so long ago, a common replacement part was a heater and control for most models. Gradually, manufacturers lowered the output of their heaters to rely more on Rinse Aid and venting to dry dishes.

Solution: Take my advice to use Rinse Aid. Also, watch your soap usage! A tablespoon is all that’s needed for any size load. Do NOT use the Pre-Wash section of the dispenser – ever. Pods are OK, but they’re borderline over soaping your dishwasher. If you use them, be sure to use Dishwasher Magic every month to clean out excess soap.

A telltale sign of a bad heater aside from wet dishes is lukewarm wash water on a high-heat or sanitary cycle. Before spending money on parts, contact us first for help in pinpointing the problem.

TIP: Use a tablespoon of good liquid soap for best results with no risk of over soaping.

I hope you gained insight on dishwasher operation. They’re amazing machines! Changes over the years make them indispensable tools for convenience, but like anything, issues come and go. Now you have a better understanding of how they work and maybe you’ll be inclined to figure out a solution before spending your hard-earned money on a repair you can do yourself!

Compact standard microwave on a shelf.

DIY Appliance Repair: Microwaves

640 427 Thomas

open tabletop microwave oven on a white backgroundWe find microwaves in just about every home we enter for service. To most people, however, they’re a mystery. We put our coffee inside, press one or two buttons, and a few minutes later we have hot coffee! Gotta love this technology!

From a DIY appliance repair perspective, when a novice attempts to repair a “not-heating” problem, half-way into the unit they back off because many components inside stand ready to punish them for trying. But, if they have the right knowledge before starting, chances are they might get the thing running again.

For now, I’ll leave the repair talk out of this and review how microwaves work and why never attempt to repair them on your own without expert help.

That said, welcome to Tin Lizzee’s latest article in our Getting Started Series! Today’s article reaches further into microwave technology. How it heats, when it doesn’t, who invented it and when. Great stuff to know!

What Makes a Microwave Work?

Each time you press “start” on the control panel of your microwave, several events take place to heat your food. The main control receives input from pressing the start button and a safety check of the door switches determines if the microwave can proceed.

After initial checks, house power (120 Vac) feeds to the main control where 120 Vac is fed directly to the high-voltage transformer where it’s doubled by the high voltage diode and capacitor circuit before reaching the magnetron. The magnetron produces microwave energy and cooking begins.

This is a simplified description of the microwave process, but overall it should give you an idea of what happens after you press start on the keypad. Many components come together and operate to produce heat. While failure of any one component would shut off high voltage, most times lights and display work, but food doesn’t cook.

Because of the extremely high working voltage of a microwave (approx. 2200 volts), it’s recommended having a working knowledge of safety and follow every step when disabling high voltage.

Inverter Technology in Microwaves

Standard microwave operation lacks a consistent, even heat in the cavity. To circumvent this, Panasonic and GE use inverter technology in some of their models. An advantage of using an inverter in place of a standard high-voltage transformer is when adjusting a cooking cycle power output to 50% for example, it outputs power at exactly 50% of its full, rated power.

A standard microwave achieves 50% power by turning its magnetron on full for approximately half of the set time in the cycle. Due to heat losses within the unit, the microwave averages 50% output, meaning power fluctuates above and below 50% power.

Inverter technology holds the advantage in cooking food with steady heating, and it can defrost food without burning the edges. However, the cost of microwaves using inverter technology is much higher than standard ones, and repair parts cost more, too.

Convection Microwaves

Tabletop convection microwave with door open showing inside.Sometimes I wonder why convection microwaves haven’t caught on yet. They’ve been around a long time, but few are sold. Perhaps the price scares people away. If I had to guess, I would say it’s because microwave cooking never got people excited enough to try it.

Convection cooking in a microwave is nearly the same as in a standard range with convection. They both use fans to circulate hot air around the cavity and bake food evenly. Wait! Bake in a microwave? Yes, that’s what convection microwaves do! Maybe now we know the reason they’re not popular. Your existing range with convection outperforms the microwave in every way, including cooking space.

One last topic about repair. I couldn’t resist.

Typical Causes of No Heat

A non-heating microwave is a huge disappointment and if you don’t have a clue of the reason, you’re more upset. I know how you feel because I’ve been there, too. Most times, the cause is a simple one, but not as easy to fix. Let me explain.

Standard microwave magnetron.By far, the most common cause of no-heat in a microwave is a failed magnetron pictured here. A simple reason, but a challenge for a novice to fix. Tin Lizzee can guide you through diagnosing this and any other symptom and find out exactly what is causing the issue.

Another common cause of several issues is the door switches. If one or more fail, lights staying on, no heat, not starting, and starting unattended are some of the symptoms you’ll see. As I said earlier, simple reason, but a challenge to fix.

Wooden Blocks Spell Final ThoughtsWho Invented the Microwave?

The story about how microwaves got their start is funny! In 1945, a man named Percy Spencer working at Raytheon was working on a radar system and microwaves produced from it started melting a Hershey’s chocolate bar in his pocket!

Initial tests were popcorn and yes, an egg. We all know what happened to the egg, right? It exploded!

From there, Spencer fabricated a sealed metal box and tested his discovery with food inside. He verified temperatures in food rose rapidly but didn’t burn the outside. Raytheon filed for a U.S. patent on October 8, 1945. The rest as they say, is history!

Single built-in wall oven in a white kitchen

DIY Appliance Repair: Wall Oven Installation Tips

640 427 Thomas

Modern kitchen with a built-in wall ovenMost of us think a wall oven works the same way as a conventional slide-in range. In many ways, it’s true. But there are differences you should know about before installing your new oven. I know they’re beautiful pieces of technology, and it’s worthwhile learning a few tips now instead of finding out the hard way!

For years, I’ve seen great installations and some very reckless and dangerous ones, too. After an installation, most customers have no idea what’s behind or around their oven. The assumption is as long as it works, all is good. Please, read on…

Self-Clean Misfortune

Wall ovens require specific minimum distances around the unit providing ample room for air flow. The open space around the oven allows it to cool properly without tripping its internal temperature sensors and stopping operation.

I won’t give specifics here because each unit has its own specifications. My point is, make sure your installers follow the specifications. They’re too important to ignore. I’ve seen too many ovens installed in spaces clearly not designed for them. That said, lack of airflow clearances creates an immediate problem.

A majority of my customers love keeping their ovens clean using the self-clean function. Aside from the steam option, a regular high-heat option remains the common choice. However, in a case of a bad installation, it’s risky to allow ovens to reach high temperatures (750-900°) for extended periods, such as during a self-clean unless proper ventilation allows sufficient airflow.

I should say all ovens I’ve seen with optional self-clean have been tested for high temps, but problems occur when insufficient airflow around the unit prevents proper cooling, tripping high-limit thermostats. This leads to a complete shutdown of the oven, or at least the bake and broil elements.

Electrical Pigtail Too Short

A potentially dangerous and novice-like installation is apparent when electrical installers don’t follow instructions and leave enough slack in the electrical pigtail connecting power to the unit. It’s too late when your wall oven gets removed for repair.

Cartoon electrician with toolboxEnough length in the power cord (pigtail) is essential to allow someone to remove the unit from the wall with enough room to maneuver around the unit while it’s sitting on an oven cart. A pigtail too short makes it impossible to remove the unit without disconnecting the pigtail from the unit, which is awkward, hard to reach, and potentially dangerous.

I should note here most units come pre-wired with a five-foot pigtail attached, but that’s not guaranteed. Please, watch carefully during the installation and insist they add enough length to the pigtail to avoid a disaster whenever the unit needs repair and must be removed from the wall!

Using Shims to Raise or Level the Unit

If an installer uses a block of wood under the unit to raise it high enough to close up gaps at the top of the opening, don’t allow it. Instead, have them use a solid piece of wood with the same footprint as the oven directly under the unit to accomplish this.

Shims shift and crush built-in exhaust vents. They’re not designed to withstand the oven’s weight, which is why they’re recessed underneath. A shim will slip during installation and end up directly below a vent, crushing it when the oven comes to rest.

Confirm Unit is Level

Before the installers leave and ask you to sign off, open the oven and check the slide-out racks. Do they slide out when you open the oven door? If yes, your unit is not level and will create major problems for you.

Hopefully, your installer won’t attempt to use shims mentioned earlier to level the unit. A basic step in a wall oven installation is to make sure the opening is correct according to spec, and level. It’s the installer’s responsibility to correct any problems before attempting installation.

Wooden Blocks Spell Final ThoughtsWe know how frustrating a bad home appliance installation can be. All Tin Lizzee techs have seen their share; that you can be sure of! I hope the tips I’ve shared with you help make your new wall oven installation a glowing success! I’ve included a link to another article about home appliance installations you might find helpful.

Modern Electric Range

DIY Appliance Repair: Electric Stoves – How they Work

640 427 Thomas

Welcome to our latest edition of the DIY Appliance Repair: Getting Started Series – Electric Stoves intended to provide our readers with a refresher about their kitchen appliances. To avoid confusion, I use interchangeably the term “stoves with the modern term “ranges”.

Why are we doing this? The answer comes from necessity because although most people are accustomed to using an electric stove, we found many don’t understand what happens inside these marvels of the kitchen. Also, we understand knowing how they work doesn’t make you a better cook (practice makes perfect) but knowing how each function works might make you a more efficient cook!

As you already know, Tin Lizzee exists to help our readers understand how to use their appliances safely and efficiently. Our commitment to you extends far beyond showing you how to make owning your appliances easier. Repair and maintenance is a big issue with appliances, and rather than put you through the hassle of calling a tech to come into your home and upset your routine, we’re only a website click away!

DIY (do it yourself) appliance repair is taking the online appliance repair space by storm, and Tin Lizzee is leading the way. We use modern technology to help diagnose or repair your appliance easily and inexpensively compared to in-home service rates!

Starting with the Basics

Conventional Five Burner Electric StoveElectric stoves in 2019 still do what they say, but changes in how they heat food might surprise you. I won’t go into all the changes, but I’ll give you some highlights.

The coil element (eyes, as some call them) is still used, but had to make room for new, instant-on, self-regulating surface elements. That’s technology at work! You won’t see modern surface elements exposed. They’re used under glass cooktops.

On conventional stoves, elements or coils connect to switches called infinite switches, and get their power directly from power entering the stove from the back through the harness. The switches are dials used to turn elements on and off.

Modern glass cooktops use a variation of the above, or a touch control where temps are adjusted by simple touches of the glass surface. Bake and broil differ in that most times ovens have their own settings on the stove control because they use relays to send power to the bake and broil elements, and some have touch controls on the glass cooktop, too.

Pretty cool stuff and getting more advanced every year!

Convection Cooking

Oven with convection baking optionCustomers often tell me they don’t use convection because they don’t understand how it works and why it’s useful. I think most people don’t use it because it’s hardly mentioned in recipes. Those who use convection love it, but not for all baking.

Generally speaking, food cooks about 20 percent faster at approximately 25 degrees less than normal. The secret of convection is a fan mounted on the back wall of the oven circulating heated air inside the oven cavity, cooking food evenly from all directions.

My wife uses convection as often as possible and I can tell you from experience, it’s a great way to cook! Chicken, meats, and vegetables cook evenly and leaves the juices. Just remember to check your food at about the three-quarter timing mark.

Safety Devices on Modern Ranges

Fortunately, ranges do have safeties built in to prevent fires from overheating. In the ahem, old days, stoves didn’t use high-temperature cutoffs to stop power from the elements in case of problems. Modern ranges have high-limit thermostats that instantly cut power to bake and broil elements if internal temperatures reach a preset limit.

If your range stops heating from all sources, suspect one of these safety devices. This is true especially if you just performed a high-temperature self-clean of the oven. In case of a blown high limit after a self-clean in a built-in oven, removal is necessary to replace the switch located on the outside back wall of the oven.

A slide-in range uses a similar device, but much easier to access on the back wall of the oven. The switches are not resettable and replacing them is the only way to get cooking again.

Over the years, safety devices vastly improved and now that technology has taken hold inside kitchens, it was only a matter of time when ranges and wall ovens would have their turn! Below are two such inventions I think you’ll like.

  • https://www.cookstop.com/ Prevents fires from unattended kitchen ranges. It uses motion sensors to detect activity in the kitchen. If it doesn’t sense movement, a countdown timer starts and shuts off the range when time expires but resets the timer again once it senses motion.
  • https://www.pioneeringtech.com/product/smart-burner/ SmartBurner prevents stovetop fires from happening with their device replacing existing coil elements. SmartBurner elements won’t exceed temperatures above that which ignites standard cooking oils and other household items.

Also, Whirlpool recently included in their ranges a variation of exposed electric elements designed to limit their temperature just below the point when they turn red. Elements have built-in current limiters preventing elements from glowing red.

Many of you might be familiar with this one. It’s the anti-tip device for stoves. It prevents the stove from tipping over when the oven door is open and something (or someone) pushes down on the open door, causing the stove to tip forward, spilling hot pans and scalding hot food! If your range is missing this device, call the manufacturer to receive a new one, and have a handyman install it. Remember: Safety First!
