Why Won’t My Microwave Shut Off?

There’s some good news to be had here, and some quite likely bad news. The good news is that no matter what folks say, you are not going to be radiated to death by your microwave. They’re generally quite safe, even if they’re running with the door open. However having said that, there are certainly risks, and the problem should not be left alone.

The bad news? The odds are pretty strong that you’re going to need a new microwave, or that replacing your microwave is going to be faster, easier, and safer.

So what causes this problem? There are actually very few causes, which lets us narrow things down pretty quickly. It tends to depend on how and why:

  • My microwave continues to run if the door is closed. If your microwave just keeps going and going until the door is opened, and the “stop” button is unresponsive, the most likely cause is the control board being faulty, or damaged. When this happens the microwave is not sending signals properly, and will think it just needs to keep running.
  • My microwave kicks on when the door is opened. A microwave that starts running when you open the door can be quite jarring, and more than a little scary. In this situation the problem is the switch (limit switch) that usually tells your microwave that it is open and needs to stop. When these switches are worn out, they can send the microwave mixed signals, often resulting in the microwave starting up.

How Do I Fix It?

In our honest opinion, you either call in a professional, or you get a new microwave. The door switch is a fairly cost-effective repair if you’ve got a pro, but the panel issue is more complex. And while there are lots of “DIY” solutions out there, videos, mostly, we can’t really in good conscience suggest repairing a microwave on your own. Why? Because a microwave carries a potentially lethal charge, even when unplugged. It’s just not worth the risk!
