Fisher & Paykel Dryer Error Code Err3

Err3 indicates that the exhaust NTC thermistor or its associated wiring circuit has malfunctioned. The exhaust NTC thermistor monitors the temperature of air leaving the dryer drum, and the control board has detected a reading outside the expected range. The dryer stops operation as a safety measure until the fault is resolved. The cause can be a failed thermistor, damaged wiring, or a faulty control board.

A power reset may temporarily clear the error code and allow the dryer to start, but if the underlying fault in the thermistor or circuit persists, Err3 will return. Resetting without repairing the root cause is not a lasting solution and could pose a safety risk since the dryer is operating without reliable exhaust temperature monitoring.

Repair costs vary depending on the failed component. A replacement NTC thermistor is generally an inexpensive part, typically in the range of $15 to $50, while labor for a service call commonly adds $80 to $150 or more depending on your location. If the control board is at fault, board replacement can bring the total repair cost to $200 to $400 or higher. Getting a diagnosis before committing to parts is recommended.

A knowledgeable DIYer can inspect the thermistor wiring harness and connector terminals for visible damage, corrosion, or loose connections and reseat them if needed. Testing the thermistor itself requires a multimeter to measure resistance at the component terminals. If the thermistor or wiring needs replacement, those are relatively accessible repairs, but control board replacement is better handled by a qualified technician.

No, it is not advisable to continue using the dryer while Err3 is active. The exhaust NTC thermistor is a key safety component that helps prevent overheating. Without an accurate reading from this sensor, the dryer cannot properly regulate heat, which could create a fire hazard. The dryer should remain out of service until the fault is diagnosed and repaired.
