What the E3 error code actually means

Your Fisher & Paykel dryer has detected a problem with the temperature sensor at the air inlet, which measures how hot the air is before it enters the drum. The sensor has lost its electrical connection, so the dryer cannot get a temperature reading and has stopped working to stay safe. A technician will need to test the sensor and its wiring to find the broken connection.

Questions people ask about E3

What does E3 mean on a Fisher & Paykel dryer?
The E3 code means the control board has detected an open circuit in the inlet thermistor, the sensor that monitors incoming air temperature. The dryer stops the cycle because it cannot receive a valid temperature reading. This is a protective response to prevent uncontrolled heating. The fault points to either the thermistor component itself or the wiring connected to it.
Is it safe to keep using my dryer when E3 is displayed?
No, you should not continue running the dryer with an active E3 fault. The inlet thermistor is part of the system that prevents overheating, and operating without a working temperature sensor could create a fire risk or cause damage to other dryer components. The dryer should remain off until the fault is diagnosed and repaired.
How much does it cost to repair an E3 error on a Fisher & Paykel dryer?
Repair costs depend on which component has failed. A replacement inlet thermistor is generally an inexpensive part, often in the range of $15 to $50, while labor for a technician visit typically adds $80 to $200 depending on your location. If the wiring harness or control board is also involved, total repair costs could be higher.
Can I fix the E3 error on my Fisher & Paykel dryer myself?
A knowledgeable DIYer with a multimeter can test the thermistor and inspect the wiring harness for breaks or loose connectors. If the thermistor tests open (infinite resistance), it can be replaced as a discrete part. However, if the fault is less obvious or involves the control board, a qualified appliance technician should complete the repair.
Will resetting the dryer clear the E3 error code?
Resetting the dryer by unplugging it or cycling the power may temporarily clear the displayed code, but the E3 fault will return as soon as the control board checks the thermistor circuit again. The underlying open circuit must be physically repaired or the faulty component replaced before the error will clear permanently.
