Fisher & Paykel Ovens F2 Error: RTD sensor open-circuit
Fisher & Paykel oven error code F2 is a high-severity fault meaning Oven RTD temperature sensor open-circuit fault. The oven cannot regulate temperature without a functioning RTD sensor. A power-cycle will clear F2 if the fault was a transient connector issue.

Answer to continue safely
Is it safe to keep using?
No. The oven cannot regulate temperature without a functioning RTD sensor. Attempting to cook may result in the oven either refusing to heat or heating without control. Do not use the oven until the sensor or wiring is repaired.
Can I reset the code?
Yes. A power-cycle will clear F2 if the fault was a transient connector issue. If the code returns as soon as a cooking cycle is started, the RTD sensor or its wiring requires physical repair.
When to stop immediately?
Stop if you notice: Oven refuses to heat at all after reset, F2 returns within minutes of every power-cycle.
Symptoms You May Notice
F2 on display, oven will not heat
The control panel shows F2 and the oven refuses to start any cooking cycle because the controller has no valid temperature input.
Oven shuts off mid-cycle
An intermittent open in the RTD circuit causes the fault to appear partway through cooking, ending the cycle unexpectedly.
Temperature display shows dashes
Instead of a cavity temperature, the display may show dashes or an abnormal reading such as 32°F, indicating no sensor signal.
Possible Causes
Failed RTD sensor — open circuit
The platinum RTD element inside the probe has failed open, returning infinite resistance to the controller.
DIY PossibleBroken or disconnected sensor wire
High heat cycling has fatigued and broken the thin sensor wires or the connector at the rear oven wall.
DIY PossibleCorroded sensor connector
Grease vapour and moisture ingress have corroded the RTD connector pins, creating a high-resistance or open connection.
DIY PossibleFaulty control board input circuit
The PCB sensing circuit for the RTD input has failed, giving a false open-circuit reading even with a good sensor.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the oven
Turn off the circuit breaker for 5 minutes, restore power, and check whether F2 clears. An intermittent break in the sensor wiring may temporarily reconnect after cool-down.
If F2 clears but returns after the oven heats up, suspect a heat-related wire fracture rather than a permanently failed sensor.

Inspect the sensor connector at the rear wall
With the oven unplugged, access the RTD sensor connector through the back panel. Check that the connector is fully seated, the pins are not bent, and there is no visible corrosion.
Clean oxidised pins gently with electrical contact cleaner and a cotton swab before re-testing.

3
Measure RTD resistance
Disconnect the RTD sensor and measure across the two sensor leads with a multimeter set to resistance. At room temperature a Fisher & Paykel oven RTD should read approximately 1,100 Ω. An OL (overload/open) reading confirms sensor failure.
Also flex the sensor lead gently while monitoring resistance — a fluctuating reading reveals an intermittent wire fracture.
Tools required
When to Call a Professional
Contact a qualified technician if:
- New replacement RTD sensor installed but F2 code persists — indicates a board input fault
- Sensor wiring runs through the oven liner and requires liner disassembly to replace
- Multiple sensor-related codes appearing simultaneously
