What F3 means on a Fisher & Paykel washer dishwasher oven

The F3 error code on a Fisher & Paykel oven indicates that the oven cavity temperature exceeded 600°F during a bake cycle. This threshold represents an abnormal operating condition, as standard bake cycles are typically controlled within a range well below that point. The control board monitors temperature continuously through the oven temperature sensor (also called a resistance temperature detector or RTD probe), and when the measured temperature climbs past this limit, the F3 fault is triggered and the cycle is interrupted to prevent potential damage or a safety hazard.

The most common cause of this fault is a failure in the temperature sensing circuit. If the RTD probe develops an open circuit or incorrect resistance, the control board may misread the cavity temperature or lose its ability to regulate heating accurately. A faulty oven element that is not cycling off properly, or a relay on the controller board that has welded closed, can also allow the oven to heat without stopping, causing a runaway temperature condition.

Diagnosis should begin with the temperature sensor. A properly functioning RTD probe typically reads approximately 1,080 ohms at room temperature, and resistance should increase predictably as temperature rises. If the probe reads outside its expected range, replacement is warranted. If the probe tests correctly, attention should shift to the bake and broil elements for signs of visible damage or shorting, and then to the controller board for relay failure.

Common causes of F3

  1. 01

    Faulty oven temperature sensor (RTD probe)

    Part replacement

    If the RTD probe has drifted out of its correct resistance range or has developed an open circuit, the control board cannot accurately read or regulate oven temperature. Test resistance at the probe connector; a reading significantly above or below approximately 1,080 ohms at room temperature indicates sensor failure.

  2. 02

    Stuck relay on the controller board

    Part replacement

    A relay on the controller board that has welded or fused closed will keep power supplied to the heating element continuously, preventing the board from cycling the heat off. The oven will overheat even when the sensor is functioning correctly.

  3. 03

    Bake element failure or short circuit

    Part replacement

    A bake element that is arcing or internally shorted may draw excessive power and generate heat beyond the board's ability to control it. Inspect the element visually for burn marks, blistering, or holes, and test for continuity shorts to ground.

  4. 04

    Loose or corroded sensor wiring connections

    Wiring / connection

    Poor connections at the RTD probe harness connector or along the wiring path to the control board can produce erratic resistance readings, causing the board to misinterpret oven temperature. Inspect connectors for corrosion, heat damage, or loose pins before replacing components.

  5. 05

    Controller board failure

    Part replacement

    If the control board itself has failed beyond a single relay, it may lose the ability to properly regulate the heating circuit regardless of accurate sensor input. This is typically diagnosed after ruling out the sensor, wiring, and elements.

Frequently asked questions about F3

What does F3 mean on a Fisher & Paykel washer, dishwasher, oven?
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.
Is it safe to use my Fisher & Paykel oven while the F3 code is active?
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.
Will resetting the oven clear the F3 error code?
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.
How do I fix an F3 error on a Fisher & Paykel oven?
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.
How much does it cost to repair a Fisher & Paykel oven showing an F3 error?
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.
