Amana AMV2307PFS 1.6 cu ft Over-the-Range Microwave 1000W 2-Speed 300 CFM Exhaust Fan F3 Error Fix: Shorted Humidity/Temperature Sensor

The humidity or temperature sensor has a short circuit. This sensor monitors cooking conditions for sensor-based cooking programs. Check the sensor wiring connections at the control board. If accessible, measure the sensor resistance — an abnormally low reading confirms a short. The sensor or its wiring harness must be replaced. If the microwave heats normally on timed cook modes, the sensor issue only affects sensor cooking programs.
