It is a Frigidaire above the oven model. Two years old. Just last night it
stopped warming food. Everything else works okay. It has power. The tray
turns. All the features still work. Just no heat. I tried different power
level settings. Nothing. I changed the plug from one outlet to another.
Reset the breaker box. Still no heating. The control pad works okay. The
lights work. Just no heat. Anyone have any idea what it wrong?
Any strange noises?

other time is sometimes a bad high voltage diode. See components (
