Possible Causes
Open or shorted condenser thermistor, Sensor detached from coil, Damaged sensor wiring, Faulty outdoor PCB sensor input
How to Fix / Troubleshooting
Safety first: Isolate power at the breaker before working on the outdoor unit.
- Locate the coil sensor: Find the thermistor clipped to the outdoor coil tubing or fins. It will have two small wires leading back to the PCB.
- Check attachment: Ensure the sensor is firmly clipped to the coil. Reattach if loose so it accurately senses coil temperature.
- Inspect wiring and connector: Look for damage or corrosion. Reseat the connector on the outdoor PCB.
- Replace sensor if needed: If resistance is out of spec or the sensor is physically damaged, replace it with a Sharp-compatible outdoor coil thermistor.
- PCB replacement: If F2 persists with a known-good sensor, the outdoor PCB is likely faulty and should be replaced.
