Question about Microwave Ovens
Everything on the microwave works except it doesn't heat up anything.
Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part
