Samsung microwave will not turn on or turns off by itself

If your microwave is not turning on, or if it is turning off by itself, it could have overheated. When a microwave has been in use for a long time and overheats, just give it 30 minutes to cool off and then try to use it again. Otherwise, you'll need to check the light, the outlet, and the power cord.

Samsung microwave will not turn on or turns off by itself

1

Inspect the light.

If the microwave's interior light is dim, it may look like the microwave is off when it really isn't.

 

  • The light inside the microwave will appear dim when looking through the tinted door. If the light comes on when you open the door, then it is working correctly.
  • If the light does not come on when you open the door and the microwave has power, then the light should be replaced. Look in your user manual for steps on how to change your model's bulb. If you don't have the user manual, check here.

 

2

Inspect the outlet.

A faulty outlet can prevent the microwave from turning on or cause it to turn off by itself. To fix this, first check the circuit breaker for the microwave to see if it has been tripped. If it hasn't, test another device in the outlet to see if it is working.
Important
Samsung does not recommend using extension cords, GFI outlets, or surge protectors with home appliances.
3

Check the power cord and plug.

Look for any damage to the cord (cracks, fraying, chafing) or the plug.

 

  • If the circuit breaker trips again while the microwave is unplugged, the problem is with your home's wiring. Contact an electrician for assistance.
  • If the wiring has been damaged, or the circuit breaker does not trip with the microwave unplugged, visit our Support Center to request service. 

 

Important
Electrical repairs should only be performed by a licensed electrician.

The vent fan on your over-the-range microwave is useful for keeping smoke and steam clear from the microwave. It will even turn on automatically if the microwave is getting too hot.

If your microwave turns on by itself after you close the door you may need to clean the door, check the latch, or ensure that the door is closed all the way. But if your cooktop lamp will not turn off, then it may just be wet from recent cooking. Follow this guide to get things back to normal.
