Microwave is Not Heating - Countertop Microwave

Possible Solutions

Is Microwave Heating? 

To test if the microwave is heating:

  • Place one cup (250 mL) of water on the turntable
  • Start the microwave oven for 1 minute on the HI setting (100% Power)

If heat rise is detected, the microwave is heating. 

Is the microwave connected to an alternate power source?

If your unit is plugged into an inverter or some other power source (for example, an inverter or generator), the power provided might be enough for the lights and the controls but not the heating source. Plug the unit in a wall outlet and try again.

Check the Controls  

Check to make sure you are using the correct controls for the type of dish you are heating.  Heating at a decreased power level may take the food longer to heat.
