Possible Causes
Blocked condenser airflow (dirty coil, obstructions), Failed condenser fan motor, Outdoor temperature sensor misreading, High ambient temperature combined with poor ventilation.
How to Fix / Troubleshooting
Safety: Unplug the unit. Allow hot components to cool before touching them.
Steps:
- Check airflow: Ensure the rear of the unit (condenser side) is not blocked by walls, covers, or debris. Maintain clear space as per GE installation instructions.
- Clean condenser coil: Remove the cabinet and gently brush or vacuum dirt from the condenser fins. Do not bend the fins.
- Verify fan operation: Spin the condenser fan blade by hand (with power off). It should move freely. With power restored briefly, confirm the fan runs when cooling is selected. If it does not, replace the condenser fan motor.
- Sensor check: Inspect the outdoor thermistor for proper placement and damage. Replace it if faulty.
- Re-test: After cleaning and repairs, reassemble the unit, restore power, and test. If F5 persists, the control board may be misreading the temperature and should be replaced.
