Troubleshooting your microwave oven

Before you even begin to troubleshoot your microwave, make sure it’s unplugged to avoid injury related to electrical shock.

Power issues

If your microwave oven hasn’t been turning on (when plugged in), take a moment to inspect the power cord and try to identify any areas that might be damaged. Make sure the outlet you’re using is working for other electronics—check the circuit breaker and make sure you aren’t dealing with a blown fuse. If everything seems to be in order and it still doesn’t work, you might need to replace the power cord.

Heating problems

Sometimes you might notice that your microwave isn’t cooking food evenly, which could indicate that there’s an issue with the magnetron—the heating element that powers microwaves.

This requires some electrical work knowledge, so you’re better off contacting a professional microwave oven repair service or buying a new appliance (if it’s more cost-effective). Some repairs can cost up to $500, so keep this in mind the next time you think it isn’t worth adding product protection.

Door switch

If your microwave oven has a broken door switch, it might not register when you close the door, preventing it from starting any heating process. To determine if this is your issue, you’ll need a multimeter to test the switch.

Essential maintenance

Once you have the repairs handled, it’s important to make sure you know how to clean microwave ovens to prevent malfunctions in the future. To keep a clean microwave, combine one cup of water with one tablespoon of white vinegar in a microwave-safe bowl and let it run in the microwave for five minutes. The steam will help loosen any grease and food particles that are difficult to clean.

Once this cycle is done, wait for the oven to cool and give it a good wipe-down with a damp cloth.


Dealing with any appliance repair can feel daunting, but it’s important that you take action as soon as possible so you don’t have to go without it for too long. Of course, if you have to pay for repairs or a replacement, it can get expensive.

Luckily, you can avoid costly repairs in the future by subscribing to Mulberry Unlimited, which gives you product protection for all your essential appliances under the same plan.
