How to Fix / Troubleshooting
Safety: Unplug the unit before servicing.
Steps to address F2:
- Check intake area: Remove the air filter and inspect behind the intake grille for the ambient sensor. Ensure it is not dangling or pressed against the coil.
- Inspect wiring: Follow the sensor wires back to the control board. Look for pinched or cut insulation.
- Reconnect sensor: At the control board, unplug and replug the ambient sensor connector to ensure good contact.
- Replace sensor: If the sensor appears damaged or F2 persists, replace the ambient temperature sensor with a GE-compatible part.
- Control board: If a new sensor does not resolve F2, the main control board may be defective and require replacement.
Tip: Keep the sensor in the airflow path, not touching metal, for accurate readings.
