Fisher & Paykel Dryer Error Code E1

The E1 code on a Fisher & Paykel dryer means the control board has detected a short circuit in the inlet thermistor, the temperature sensor that monitors incoming air. The sensor's resistance has dropped abnormally low, which the control board flags as a fault. The dryer will not operate normally until the issue is resolved.

No, you should not continue operating the dryer with an active E1 fault. A shorted inlet thermistor means the control board cannot accurately monitor air temperature, which removes an important safeguard against overheating. Continued use in this state could pose a fire risk or cause damage to other components.

A power reset may temporarily clear the E1 code from the display, but the fault will return once the control board detects the shorted thermistor again during the next cycle. Resetting does not fix the underlying hardware problem. The inlet thermistor and associated wiring must be inspected and repaired for the code to clear permanently.

A technician-level repair is possible for those comfortable with a multimeter and basic appliance disassembly. The inlet thermistor and its wiring harness need to be tested for resistance and continuity. If the thermistor is confirmed shorted, it can be replaced as a discrete component. If you are not comfortable working with appliance wiring, a qualified technician should perform the diagnosis.

If only the inlet thermistor needs replacement, parts costs are typically modest, often in the range of $15 to $50 for the sensor itself. Adding professional labor, total repair costs generally fall between $80 and $200 depending on your location and service provider. If the control board is involved, costs will be significantly higher.
