How to repair a microwave that is not heating
The following steps outline possible causes and solutions to why your microwave is not heating. If these steps don’t work, or if you are unsure of how to proceed, contact a qualified service technician.
Step 1: Check the microwave’s power supply
Check to make sure the microwave’s power supply is plugged into a grounded, operational outlet. If you are unsure of whether or not the outlet in use is functioning, try plugging in a lamp or other small household item to verify whether or not it is working. If the outlet appears to be operating correctly, check to see if a circuit has been tripped or a fuse has blown in your home.
Step 2: Ensure the door is closing properly
As a safety precaution, a microwave will not heat until the door is in a properly closed position. Check to make sure the microwave door is firmly shut before attempting to operate. If your microwave is brand new, be sure to remove the shipping spacer along with any residual packaging that may be preventing the latch from securing fully.
Step 3: Check the microwave’s controls
Make sure your microwave’s controls are turned to the appropriate setting for what you are trying to heat. If the current settings are operating at a lower power level or cook time than what is needed to heat your dish, this is likely the reason why your food is coming out cold and you will need to adjust the power level accordingly.
Step 4: Check for error or display codes
If your microwave encounters an error or is set to a specific mode, the unit will not heat and a code will appear on the display. Control Lock and Demo Mode are two common codes that will prevent the appliance from heating, and will need to be disabled in order to restore function. To identify and resolve a particular code, consult your model’s Use and Care Guide.
