Fisher & Paykel Dryer Error Code E5

The E5 code on a Fisher & Paykel dryer signals an inlet thermistor signal failure. The inlet thermistor monitors the temperature of air entering the dryer drum, and the control board has detected that the sensor's signal is outside the acceptable range or is absent entirely. This causes the dryer to stop operating as a safety precaution. The fault points to a failed thermistor, a wiring issue, or in less common cases, a faulty control board.

You should not continue to operate the dryer while the E5 code is active. The inlet thermistor is part of the system that prevents the dryer from overheating, and running the appliance without a reliable temperature signal creates a risk of overheating or fire. The dryer should remain off until the fault is diagnosed and repaired.

Repair costs depend on which component has failed. Replacing an inlet thermistor is generally an affordable repair, with parts typically ranging from $15 to $60 and labor costs varying by region. If the control board requires replacement, costs can range from $150 to $350 or more including parts and labor. Getting a diagnostic assessment from a qualified technician before committing to a repair is advisable.

A knowledgeable DIYer can attempt to diagnose this fault by inspecting the wiring harness and connector at the inlet thermistor for visible damage, and by testing the thermistor's resistance with a multimeter. If the thermistor has failed, replacing it is a moderately straightforward repair. However, if the control board is involved, professional service is recommended to avoid further damage.

A power reset by unplugging the dryer for a few minutes may temporarily clear the E5 code, but it will return if the underlying fault is not repaired. If the thermistor or wiring is physically damaged, no reset will provide a lasting fix. A reset is useful only to confirm whether the fault is intermittent or persistent.
