GE JVM7195SKSS 1.9 cu ft Smart Over-the-Range with Scan-to-Cook MECH-NOHEAT Error Fix: Microwave Runs But Does Not Heat

Error code MECH-NOHEAT on the GE JVM7195SKSS 1.9 cu ft Smart Over-the-Range with Scan-to-Cook means: Microwave Runs But Does Not Heat. The microwave appears to run normally (lights on, turntable spinning, fan running) but food does not heat up — the magnetron has most likely failed; other possible causes include a failed high-voltage diode, defective high-voltage capacitor, or faulty high-voltage transformer; WARNING: the high-voltage circuit operates at approximately 4,000 volts DC and the capacitor can retain a lethal charge even when unplugged — this repair should only be attempted by experienced technicians; replacement of the magnetron is often not cost-effective on budget microwave models
