Hotpoint RVM5160DHWW 1.6 cu ft Over-the-Range Microwave with 1000 Watts and Sensor Cooking F1 Error Fix: Oven Cavity Thermistor Open Circuit

The microwave oven cavity temperature sensor (thermistor) has an open circuit and is not providing a temperature reading to the control board — this affects sensor cooking modes and auto-cook functions that rely on measuring cavity temperature to adjust cooking time; manual cooking modes (timed cook, power levels) may still function normally; the thermistor is typically a small component mounted inside the top of the microwave cavity; test it for resistance with a multimeter (should read approximately 50K-100K ohms at room temperature, depending on model); an infinite/OL reading confirms an open circuit
