Microwave ovens provide a quick and convenient way to heat up food and liquids. With just the press of a few buttons, you can make an entire meal in a quarter of the time it would take in a regular oven or stove. However, like any other appliance, your microwave can experience issues that require repairs. Most of the time, the repairs should be handled by an experienced contractor, but there are a lot of do-it-yourself repairs that you can try first. This guide goes over some common problems with microwaves and how to troubleshoot them:
Microwave Cooks Food Unevenly
There are a few different causes that will make the appliance cook food unevenly or even too slow. Try the following:
Check the motor on the turntable. You can do this by removing the grill on the bottom of the microwave and testing the probes on the terminals. If the reading is infinity, it's a sign the motor is bad and should be replaced.
Check the power outlet that the microwave is and see how much voltage it is. It should be higher than 120 volts. If it isn't, replace the breaker or power supply.
Microwave Doesn't Turn On
Another common issue is the microwave not turning on anymore. In order to troubleshoot this, you should:
Check the voltage like in the previous step.
Check the power cords for signs of damage or scorch marks. If there are any, the microwave power cord should be replaced. Using damaged cords is an electrical hazard.
Check the fuse inside the appliance. You need to remove the fuse first. It's best to use fuse pullers when you remove fuses. Test the fuse with probes. If the reading is anything but zero, it is a sign the fuse needs to be replaced.
Inspect the switch for the door. Sometimes gunk builds up around the edges of the switch and permits it from latching properly. The microwave may be programmed to not run when the door is open, so if it isn't shutting all the way it won't start.
Anytime you are working with electrical appliances, you need to always turn off the power before performing any repairs. By not doing so, you run the risk of electrical shock. If the microwave needs a repair that is electrical, you should hire a professional to handle the repair for you. You may even be able to get the repairs for free or at a lower than usual cost if you are under warranty.
