Frigidaire FGMV176NTF 1.7 cu ft Gallery Over-the-Range with SpaceWise Rack F3 Error Fix: Temperature Sensor Open Circuit

The cavity temperature sensor has an open circuit — the control board cannot read the temperature. Check the sensor wiring for loose connections or damage. Measure the sensor resistance — it should have a measurable value that changes with temperature. If the sensor reads infinite (open), replace the temperature sensor. On some models, the sensor is integrated into the control board.
