Fisher & Paykel Washer, Dishwasher, Oven Error Code F3

On a Fisher & Paykel oven, the F3 code means the oven temperature exceeded 600°F during a bake cycle. The control board detected a runaway heating condition and shut the oven down as a safety measure. This is an oven-specific fault and does not apply to Fisher & Paykel washers or dishwashers. The most likely causes are a faulty temperature sensor, a stuck relay on the control board, or a shorted bake element.

Disconnecting power to the oven for a few minutes may clear the F3 code temporarily, but the fault will return if the root cause is not repaired. If a sensor is faulty, a relay is stuck, or an element is shorted, the oven will continue to overheat and trigger F3 again. Resetting is only useful as part of the diagnostic process, not as a fix.

Repair costs depend on which component has failed. A replacement temperature sensor is typically in the range of $20 to $60 for the part, while a bake element can range from $30 to $80. A controller board replacement is the most expensive possibility, often ranging from $150 to $350 or more depending on the model. Adding a professional technician's labor will increase total costs accordingly.

No, you should not continue using the oven until the fault has been diagnosed and repaired. An F3 code indicates the oven has already reached a dangerously high temperature, which poses a risk of fire and damage to the appliance. Disconnect power to the oven until the underlying cause is identified and corrected.

Start by testing the oven temperature sensor (RTD probe) with a multimeter, checking for a resistance reading near 1,080 ohms at room temperature. If the sensor tests correctly, inspect the bake element for visible damage and test for shorts. If both components appear sound, the controller board, specifically its heating relay, should be evaluated. Replacing the faulty component will resolve the error.
