Even if you have the best microwave, you may eventually run into issues. One issue can be due to not using microwave-safe containers. Sometimes, a microwave oven will have power problems like losing power or turning off. This is something you need to take care of as soon as possible. If left untreated, electrical problems may cause dangerous microwave fires or damage to other kitchen appliances. So, if you're wondering why did my microwave turn off, read our guide below.
KEY TAKEAWAYS:
- If your microwave turns off by itself, you have a safety issue.
- Bad door switches and overheating are the most common causes for your microwave to power off on its own.
- Before testing your microwave, unplug it and wear safety equipment. If you're at all unsure of your ability to troubleshoot the problem, reach out to a repair pro.
Why Do Microwaves Lose Power?
If you've tried to use your microwave but see the digital display panel is off, there are a few reasons this has happened. One is that, somehow, your microwave's electrical components have become damaged. That said, it could also be your microwave's enhanced safety measures protecting your home from a power surge.
Just like the F-3 error code, you should seek professional service to repair internal components like control boards, faulty capacitors, or defective diodes. Other issues you may be able to handle on your own, such as resetting a microwave.
Insider Tip
A control board issue is rare compared to other microwave problems, and it should be the last issue you investigate.
Broken Door Switches
The most common failure is due to the interlock switch. A faulty door switch will cause many issues, like triggering circuit breakers and safety features, even if you keep the microwave shut. You can check your microwave door switch for continuity with a voltage capacitor underneath the control panel.
Internal Fuse
Cavity fuses like an amp fuse, ceramic fuse, or thermal fuse, are located on the microwave board. If your microwave fuses fail, it may be a sign of other issues. For example, if the door switches are bad, your ceramic fuse might blow when you shut the door. If this is the case, you may need our guide on how to replace a fuse in a microwave.
Overheating
Another reason your microwave might automatically shut off is due to overheating. Among other safety monitors, the heat sensor protects the components of your microwave from getting too hot. If this happens, the microwave's internal safety device is working correctly. Make sure your appliance has enough ventilation and is free from dust and dirt. A clean and ventilated microwave shouldn't trigger the microwave safety monitors.
Warning
Contact an appliance repair schedule service if you don't have experience working on appliances. Microwaves are dangerous and can shock you, especially if you open up the oven cavity.
F.A.Q.S
Why does my microwave make a crackling noise when not in use?
If your microwave makes noises when it's off, it is likely caused by its internal components. For example, your microwave fan will turn on to regulate the internal temperature of the appliance.
How much extra radiation am I exposed to if I stick my hand in the microwave right after it turns off?
You don't have to worry about radiation from your microwave. It doesn't have enough energy per photon to cause cell or chemical damage to your body via electromagnetic radiation.
Why did my microwave turn on by itself?
If your touch panel or control panel membrane fails, it is usually due to worn button springs. If these springs stick, they may trigger cooking functions without your say-so. Contact a professional for microwave repair because broken door panels can be dangerous.
STAT: A US Department of Energy survey found that 29% of Americans use their microwave at least two times a day. (source)
