James C Floyds Knobs , IN November 10, 2021 Microwave faulted and displayed hot after reset fault cleared but it would not heat food Replaced HV Diode & Magnetron. Not sure which fixed it.....both the new and old diode read open with my multimeter. But it works now and I think it heats quicker than it did before the repair.
