GE Microwave Error Code HOT—OVEN IS HOT

This message means the internal cavity temperature has exceeded 200°F, which causes the control board to disable sensor cooking functions. It is a protective thermal interlock, not an error or malfunction. The message clears automatically once the oven cools below that threshold. No reset or repair is needed under normal circumstances.

Yes, the microwave is generally safe to use during this condition. Timed cooking functions typically remain available even when sensor cooking is disabled. The message simply prevents sensor-based cooking modes from running because the elevated cavity temperature would interfere with accurate humidity sensing. Avoid continued high-power use until the unit has cooled to prevent compounding the heat buildup.

If the message appears only after heavy use or heat from a nearby range, no repair cost is involved since it is a normal operational condition. If a faulty temperature sensor is confirmed, sensor replacement parts typically range from $15 to $60 depending on the model, with professional labor adding $80 to $150. A control board replacement, if required, generally costs between $100 and $250 for parts alone.

The most effective fix is simply to wait. Open the microwave door to allow heat to escape and give the unit 10 to 20 minutes to cool down. Once the internal temperature drops below 200°F, the message will disappear on its own and sensor cooking pads will become active again. If the message persists on a unit that has not been used and is at room temperature, a technician should test the temperature sensor circuit.

Unplugging the unit will not cool the cavity any faster, and the message will likely return as soon as power is restored if the temperature is still above 200°F. The condition must be resolved by actual cooling, not a power cycle. Once the oven temperature drops below the threshold, the control board clears the message automatically without any manual reset.
