Microwave not heating — Los Angeles, California
A microwave that runs but doesn't heat food usually has a failed magnetron, defective diode, or blown high-voltage capacitor. These components carry lethal voltage even when the unit is unplugged, so repairs require a trained appliance technician. A pro can diagnose the fault, replace the magnetron or diode, and test for safe operation — or advise replacement if the repair cost exceeds the unit's value.
