Is Your Appliance Worth Repairing?

May 13th, 2021

Appliances help us keep our lives on track. Where would we be without our refrigerator/freezer, washing machine, dryer, dishwasher, microwave, and garbage disposal? When any one of these stops functioning, it can quickly turn from an inconvenience into a disaster. Your immediate impulse might be to replace the appliance that is broken. But is that always the right option? Here is a quick guide to help you decide whether your appliance is worth repairing.

How Much Would It Cost?

Generally, the larger the appliance the costlier it is. So if your stove breaks, you’re looking at a major investment to buy a new one. But if your microwave goes, you can purchase one for under $75. Consumer Reports advises that if the cost to repair your appliance is greater than half the cost of a new one, it makes sense to replace it. Obviously you won’t know how much the repair would cost without consulting an appliance repair service. At Dave’s Appliance, our experts can diagnose your appliance’s problem and give you an estimate for the repair. With all of that information, you can make an informed decision.

Which Appliance Is it?

Other than cost, you have to consider how much you value your current appliance. Your refrigerator/freezer may have external ice and water dispensers, pull-out shelving, and other features you really appreciate. Your washer and dryer may fit just perfectly into the space in your utility room. Maybe you love to cook and bake and your stove suits you perfectly. It might even be that your appliances coordinate with your decor. These are definitely legitimate reasons to hesitate about replacing them when they break. Again, a visit from one of the friendly members of Dave’s Appliance team will help you understand the extent of your problem.

How Old Is It and Is It Still Under Warranty?

Major appliances like refrigerators or chest freezers often last from 10 to 20 years. Other appliances like trash compactors have an average life span of about 6 years. Most appliances also come with warranties, and often those can be extended if you choose to do so. When an appliance breaks down, it would be a good idea to find out if its warranty is still in force. If it’s not, check to see what the average life span is for your brand of that particular appliance.

What’s The Environmental Impact?

Often, the environmental impact of repairing or replacing isn’t considered at all. But perhaps you should think about it. If your appliance is old and inefficient, it may be using a lot of electricity. That’s bad for the environment and bad for your utility bills. If your appliance was made after 1992, it should have an Energy Star Rating to let you know how efficient it is. You can compare it to current appliances’ efficiency. On the other hand, your old appliance can’t just be thrown out. Major household appliances are banned from landfills in Wisconsin and the state urges that they be reused or recycled. In many places in Wisconsin, appliances are not picked up at the curb with other recyclables, nor are they accepted at many general recycling drop-off sites. It may be the more environmentally-responsible choice to repair rather than replace.

Whatever your appliance concern, the experts at Dave’s Appliance will be able to tell you what the problem is and help you decide whether or not it’s worth repairing. Give us a call.

How To Test Microwave Ovens

October 5th, 2020

Microwave ovens are like any other electrical appliance, in that it will gradually wear out. This is due principally to gradual degradation of the magnetron tube that generates the energy that heats the materials that you put into it. If you’re interested in how a magnetron tube converts high-voltage electricity into microwaves, there’s a Wikipedia entry here. For most of us, though, it’s enough to know that over time, the tube will wear down and produce less microwave energy, requiring more time to bring things to the desired heat. In higher power-rated microwaves, the degradation may be less noticeable for a time, but for lower powered units, a fall-off may mean that the device is no longer very useful.

If you’ve thought that your microwave no longer cooks as quickly or as thoroughly as it used to, you may be correct. One common sign is that you hit a preset power and time setting, such as to pop microwave popcorn or heat a coffee mug of water, and it doesn’t quite do the job. Of course, the speed at which it cooks when it is new depends on the power rating. Higher powered microwaves are often rated at around 1200 Watts, and some even higher. Low power models are typically 700 Watts rated. Anything under 700 Watts is probably not very good for cooking food. You can see how to convert power ratings and times required here.

Down and Dirty Test #1
So, how can you test? Well, the most obvious way is to find out what your microwave’s power rating is (often noted on the back of the appliance, and certainly in the owner’s manual), and use the time for specified power instructions on some microwave friendly food’s preparation instructions. If you don’t want to waste food, a packet of microwave popcorn might be a good place to start. Presumably, if your microwave isn’t heating to what the power rating and time of preparation expectations are, it isn’t performing to specifications, although this assumes that the preparation instructions are accurate.

Down and Dirty Test #2
Another down-and-dirty way of testing is to fill a coffee mug with water and boil it on high (the microwave’s default setting) for 1 minute. The water should in most cases have begun to boil by then. Again, though, this is just presumptive proof that it’s not operating to specification. What it means, more than anything, is that our expectations have been raised to the point where we think that is a reasonable time in which water ought to boil in a microwave.

More Scientific Test: The JIS Microwave Power Method

You can find this method outlined at Celtek Electronics. You need:℃

2 identical 500 mL beakers (or other microwavable containers)
An accurate thermometer
A stirrer (wooden is good, like a popsicle stick/tongue depressor/coffee stirrer)

1) Stir and divide 1000 mL of water that’s 20℃ plus or minus 5℃ into the two containers, to ensure that they are both of the same temperature.
2) Measure the temperatures of both, add those temperatures and divide by two to average the results.
3) Position both containers near the center of the microwave’s turntable. At full power, switch the microwave on for 60 seconds.
4) Remove both containers immediately, stir, and measure the temperatures the same way: note each and add together, then divide by two to average.
5) Now subtract the starting temperature average from the ending temperature average (for example, 40 minus 20 equals 20). Now take that number, and multiply by 70 to give the estimated wattage. In this case, 20 times 70 equals approximately 1400 Watts.

Compare that to the manufacturer’s specified power. If it’s not near the mark, it may be time to get a new microwave oven. Even if it’s close, it may be that your life circumstances have changed, and you find you need a larger capacity or a higher power rating for a growing family, or maybe you’re doing more food preparation than you used to, or you just want a change.

Whatever is causing your dissatisfaction with your microwave, Dave’s Appliance has the experience and the selection to get you the unit that will suit you best. They are happy to put their experience at your service. Give them a call.

How To Fix a Microwave That Won’t Turn On

October 5th, 2020

It could be a simple fix, or not. If it is, you are going to have to be a little handy, and it helps to have a multimeter and to know how to use one. When in doubt, call a professional or replace the unit.

The first thing is to check that it is properly plugged in, and to check the circuit breaker. You might want to try testing the outlet with another appliance before making a trip to the circuit box.

If all of that seems fine, the first thing to check will be the door latch. Has it been sticky? Has it been loose or not closing properly the first time? If the safety interlock on the door isn’t making proper contact, this will prevent the microwave from turning on. The reason is that the door must be properly closed in order to prevent stray microwaves from endangering your health. It is a safety feature.

Testing the Interlock Switch

1) Unplug the microwave.
2) Check the hooks that are on the door to make sure that they are not deformed. If they are, this can prevent the interlock switch from permitting the microwave to be turned on. You can think of the door hooks as being a kind of key that activates the interlock switch.
3) If the door hooks seem to be fine, and lining up properly with the interlock switch, you can remove the interlock switch by unscrewing it from the microwave.
4) Now set your multimeter to Rx1, turn it on, and touch the probes to the terminals. You should see a reading of “0” [zero], indicating that the circuit is continuous.
5) If your switch is not continuous, you can try spraying it with contact cleaner, thought that is likely a temporary solution. If it is not, you will want to get a replacement switch.

If you feel uncomfortable with any of these steps, you are probably best off contacting Dave’s Appliance instead of fixing it yourself.

Checking the Ceramic Fuse

If your microwave won’t start, and you can’t get a reading on the display, it could be that the ceramic fuse has blown. This fuse is there to protect the electrical components of your microwave from damage in case of power fluctuations. If the fuse is blown, nothing on your microwave will work until it is replaced.

1) Unplug the microwave.
2) Locate the fuse near the power cord. This may entail removing the microwave from its cabinet. Remove it.
3) As with testing the interlock switch, set your multimeter to Rx1, activate it, press the probes to both ends of the fuse. It should read “0” [zero]. If you don’t have a multimeter, and you happen to have a replacement fuse, though that is unlikely, you can try replacing it, but be very careful to make sure you have the proper replacement. You can also bring your fuse to a local electrical supply shop, and have them test it for you and get a replacement, if that is the problem.

Again, if any of the above makes you uncomfortable, it is best to seek professional help. The folks at Dave’s Appliance have seen these problems thousands of times, and can give you the advice you need.

For all other potential problems involving microwaves, you are best leaving things to the pros, unless you really have some good electrical problem-solving chops. Check to see whether your unit is still under warranty. Or maybe it’s just time to replace your microwave, although in many cases owners have become so accustomed to how a particular microwave works that they are reluctant to part with it. Or perhaps the microwave you have is part of a kitchen appliance ensemble that matches, and you don’t want to disrupt the way it hangs together.

At any rate, the helpful professionals at Dave’s Appliance are happy to advise you in the way that best suits your needs. Give them a call.

Microwave Not Spinning? How to Fix a Microwave Tray that Won’t Turn

February 26th, 2020

Microwaves make your life so much easier. But if the turntable inside the microwave stops functioning, then it’s likely the food will not cook evenly. There are a number of reasons your microwave tray may stop spinning. In this post, we will examine each potential cause and how you can fix it.

Interior Debris

Sometimes when you microwave food, food particles can splatter all over the interior of the oven. It is possible for them to become encrusted on the tracks of the roller guide or the coupler. The solution is extremely simple: thoroughly clean the interior of the oven.

Remove the round, glass microwave tray and the roller guide; check to make sure that there is no stuck-on food that might inhibit turning

Wash in warm soapy water

Wash out the interior of the microwave

Replace roller guide and tray

Test it out and if your tray turns, you’ve solved the problem!

Roller Guide

If a thorough cleaning doesn’t do the trick, the issue may be with the roller guide. The roller guide works with the coupler to rotate the turntable. It has a center part that fits on the coupler and then the outer circle guides it along the track. When you take the roller guide out to clean it, make a comprehensive inspection of it.

Examine the wheels on the guide to ensure they turn freely with no resistance

Look for any signs of wear, cracking, discoloration, or damage

Look at the fitting for the coupler; any cracks or damage may mean that it is not engaging properly

If you find any issues, you will need to have a replacement roller guide.

Coupler

The coupler is the center piece in your microwave oven that attaches to the drive motor below. It connects to the roller guide as well. If the coupler is damaged, then the energy from the drive motor is not being transferred to the roller guide. Here’s how to figure out if the coupler is the culprit.

Disconnect your appliance from the power source

Locate your drive coupler – in most models, that means removing the tray and roller guide; in some models, you will need to remove the motor from the floor of the microwave to find the coupler

Remove coupler – most models will have a three sided coupler that will just pull off of the motor shaft.

Examine coupler – it normally has a D shaped opening that fits tightly onto the motor shaft and you should look for cracks, discoloration or wear

If you identify any issues, you will need a replacement drive coupler.

Drive Motor

The drive motor that powers the turntable is located in the floor of the microwave. If you have eliminated all of the causes above, you will need to check the drive motor. This is a more extensive undertaking and you may want to contact the experts at Dave’s Appliance. If you decide to tackle it yourself, then you should be prepared with a multi-meter and other tools.

Disconnect your appliance from the outlet

Remove drive motor – you will need to remove the cabinet in order to get at it, and then disconnect the wires and retaining screw

Test drive motor – using a multimeter set to the highest setting, test for continuity by touching the probes to the terminals; you should receive a reading of zero if your motor is functioning properly.

If your test results aren’t zero, or if your microwave makes grinding noises, then you may need a replacement drive motor. Dave’s Appliance can help.

Clean Your Appliances With an Earth-Friendly Attitude

June 17th, 2016

As you walk down the aisle in nearly any grocery store, you’re greeted by high-priced cleaners that have every chemical mixture possible. Although these chemical combinations are effective, they’re not necessarily good for the Earth. Take a close look at some of the ways that you can clean those appliances without relying on chemicals. The Earth and your health will thank you in the end.

Open the Refrigerator’s Door

You may place a baking-soda container in your refrigerator so that odors are neutralized, but it doesn’t scrub the interior walls for you. Grab a spray bottle, and add an equal amount of water and vinegar to it. Shake up the mixture and scrub. Vinegar is very acidic, and it kills off germs and fungus with a very low concentration. Use a soft rag during your scrubbing process in order to protect the refrigerator’s walls from any scratches. (more…)

Pinpointing When Your Microwave Requires a Service Call

April 28th, 2016

Even a built-in microwave oven might need Milwaukee microwave repair

In the past, reheating food used to require the use of the stovetop or oven, which took considerable time. By the 1980s, the microwave was slowly becoming the solution to leftover night. Place the food inside the appliance, add a time to the control panel and your meal is ready in a matter of minutes. However, your appliance may require a visit from a Milwaukee microwave repair professional at some point. Examine your kitchen for any of these symptoms that indicate some repairs are necessary right away.

Cold Food

You may have set the microwave for three minutes, but your food is still incredibly cold. There could be several issues at play, which requires a professional’s expertise to solve. An internal part, such as a diode, might be bad. This electronic component acts as a heating element within the appliance. Alternatively, you could have a bad door switch. If the appliance senses that your door isn’t properly sealed, it won’t activate any heat or radiation. (more…)
