If your microwave is not heating food, it might be a simple fix. Identify the problem by reading the article below. You’ll learn how to fix a broken turntable, check for a GFCI outlet, and rewire the microwave. In addition, you’ll learn how to check for a faulty fan motor. Listed below are a few tips to help you repair your microwave. Just follow these steps and you’ll have a working microwave in no time!
Identifying a problem with a microwave
If your microwave does not turn off after the timer has expired, there could be several reasons for the problem. It could be a fault with the main control board. Check for signs of burnt or short-circuiting components, or it could be a faulty door switch. If the timer does not work, you may have to unplug the microwave to stop it. In some cases, sparking inside the microwave can also be an indication of a problem with the Waveguide Cover. It may be time to replace the Waveguide Cover. In addition, if the underlying connectors burn out, you may need to replace the waveguide cover.
The magnetron tube is the most common cause of a faulty microwave. Fortunately, most magnetron tubes are covered under warranty. If you have a microwave that is still under warranty, contact the repairman. Otherwise, you can check it yourself. To check for burnt spots, remove the case and examine the inside of the tube. It might be a blown fuse, a high-voltage capacitor, or a diode.
Troubleshooting a broken turntable
If you have a broken turntable in your microwave, it may be time to replace the motor. In many cases, the motor is faulty. You can test its continuity using a multimeter. If it doesn’t, you should replace the entire microwave. The drive coupling is another common source of broken turntables. Here are some tips for troubleshooting a broken turntable in a microwave.
If you hear a grinding sound, the turntable may not be turning. It’s possible that the motor is not charging properly. To test the motor, you can use a continuity tester or another multimeter to determine if it is charged properly. In some cases, damaged wiring can also cause this problem. If you have an old microwave, you can buy a replacement motor from a microwave store.
Checking for a GFCI outlet
Many microwave ovens are plugged into a dedicated circuit. However, some are plugged into the same circuit when placed on a countertop. A GFCI outlet and a circuit breaker protect two separate appliance outlets. If the outlet is tripped, reset the GFCI outlet or switch the breaker to the “OFF” position. If you’re not sure how to reset a GFCI outlet, you can perform a reset by pressing the Reset button on the GFCI outlet.
First, locate the fuse. This is usually located near the power cord. You may need to remove the microwave cabinet to locate it. Use a multimeter set to Rx1 and press the probes against the fuse. The meter should show a “0.” If the fuse is not blown, try to replace it. If you do not have a multimeter, you may also want to visit an electrical supply store to test the fuse.
Identifying a faulty fan motor
Identifying a faulty fan motor in a microwave is relatively easy, and you can easily replace the faulty motor yourself. The problem typically involves a worn or burned motor located below the plate. However, the problem could also be related to another part of the microwave, such as the control panel, main control board, or touchpad. Fortunately, identifying a faulty fan motor in a microwave is easy, and you can do it yourself without professional help.
A faulty fan motor can cause a lot of noise inside your microwave. If you notice excessive noise when using your microwave, you may need to replace it. Disassembling and inspecting your microwave is required to diagnose the problem. In some cases, a faulty fan motor is a sign of a more serious problem. If you suspect it’s the fan motor, it’s best to call a microwave repairman.
Checking for a broken drive motor
If you’re experiencing noise coming from your microwave, you should be looking for a broken drive motor. These motors turn the microwave tray while the oven is running. To access the motor, remove the microwave’s glass tray and unplug it from the electrical outlet. To repair the drive motor, make sure to follow the same steps as you did when removing the old motor. The new motor should have the same wiring and clips. It should also have the same shaft orientation as the old one.
Inspecting the drive motor is more involved than identifying a damaged turntable. To start, you need to turn off the power source and then unplug the appliance. Next, turn on your multimeter and place the probes on the two wires that lead to the drive motor. If you see any resistance or no current flowing, the drive motor is most likely damaged and needs to be replaced.
Checking for a broken roller guide
The most fragile part of your microwave is the roller guide. It is made of thin plastic with tiny wheels that help spin the glass plate based on a motor drive. If a roller guide is broken or dirty, the plate may not spin smoothly or may ‘drag’ on the motor. When you repair this part, the plate will no longer spin with the food. If you don’t notice a problem immediately, you may need to purchase a new one.
If the roller guide is broken or damaged, it is likely that a drive coupler or magnetron is at fault. To check this component, unplug the microwave and remove the glass tray. In some cases, you may have to remove the motor to access the coupler. A licensed technician can offer microwave repair services to get your microwave working again. If you don’t have the time or the tools to diagnose this component yourself, consider hiring a microwave repair technician.
