Fisher & Paykel Dryer Error Code 9

Fault code 9 on a Fisher & Paykel dryer means the exhaust temperature sensor is reading under temperature, which the control board interprets as an open circuit or a disconnected sensor. The dryer cannot safely regulate heat without a valid sensor signal, so it stops operation and displays this code. The most common causes are a loose connector, a broken wire, or a failed sensor.

No, you should not continue using the dryer while fault code 9 is active. Without a functioning exhaust temperature sensor, the control board cannot monitor heat levels, which creates a risk of overheating. Resolve the sensor fault before running any drying cycles.

Repair costs depend on what component has failed. If only a connector needs to be reseated, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the exhaust temperature sensor itself needs replacement, parts and labor combined generally fall in the range of $100 to $250, depending on your location and the technician's rates.

Start by unplugging the dryer and locating the exhaust temperature sensor and its wiring connector. Check that the connector is fully plugged in and that no wires appear pinched, burned, or broken. If the connector is secure, use a multimeter to test the sensor for continuity and proper resistance, and also check the harness for continuity from the sensor back to the control board. Replace any component that tests as open circuit.

Resetting the dryer may temporarily clear the fault code, but the code will return if the underlying wiring or sensor problem has not been fixed. The fault is caused by a physical circuit issue, such as an open connection or a failed sensor, that a reset alone cannot correct. A proper repair of the sensor circuit is required for the code to stay cleared.
