Fisher & Paykel Dryer F3 Error Code
The thermistor (temperature sensor) is shorted or open, causing inaccurate temperature readings.
Common causes
- Faulty thermistor
- Damaged wiring to thermistor
- Loose connector
How to fix it
- Unplug dryer and locate the thermistor (usually near the heater housing).
- Disconnect wires and measure resistance with a multimeter (should be around 10k-50k ohms at room temperature).
- If resistance is out of range, replace the thermistor.
⚠ When to call a pro: If the thermistor tests fine but error persists, the control board may be faulty; call a technician.
