Sharp microwave does everything but heat
4 year old sharp microwave that overnight decided it'd do everything but
heat. All functions normal, except heat. There is 120V applied to the HV transformer primary, secondary measures 150 ohm, filament on both transformer and magnetron shows negligible ohms, diode tests good on back voltage, HV cap appears OK, magnatron does get very hot after a couple of ten second tests...... ????? I've had several with bad micro switches, HV cap, etc., but this one does everything but heat for no reason..... TIA |
