Fisher & Paykel Ovens F1 Error: Oven overtemperature

Fisher & Paykel oven error code F1 is a high-severity fault meaning Oven overtemperature fault. An overtemperature fault presents a fire risk. A power-cycle may clear a transient F1 code, but if the fault condition still exists (stuck relay, shorted sensor), the overtemperature event will recur.

Answer to continue safely

Is it safe to keep using?

No. An overtemperature fault presents a fire risk. Do not use the oven until the root cause — runaway element relay, shorted RTD, or failed control board — has been diagnosed and repaired by a qualified technician.

Can I reset the code?

Yes. A power-cycle may clear a transient F1 code, but if the fault condition still exists (stuck relay, shorted sensor), the overtemperature event will recur. Only use a reset as a diagnostic step, not a permanent fix.

When to stop immediately?

Stop if you notice: Oven cavity is visibly glowing or producing smoke, F1 returns immediately after every power-cycle.

Symptoms You May Notice

F1 displayed and oven shuts down

The control panel shows F1 and the oven cuts power to all heating elements immediately as a safety response.

Audible alarm sounds

A continuous or intermittent beep accompanies the F1 code, alerting the user to an unsafe temperature condition.

Oven cavity excessively hot

The interior may be visibly overheated; opening the door releases a strong blast of heat well above the set temperature.

Possible Causes

1

Runaway bake or broil element

A failed bake or broil element relay on the control board has stuck closed, allowing continuous current flow and uncontrolled heating.

Requires Professional
2

RTD temperature sensor short-circuit

An RTD sensor that has shorted internally reports a falsely low temperature, causing the controller to drive elements to maximum output.

DIY Possible
3

Thermal cutoff tripped

The oven's thermal cutoff fuse has detected a dangerously high cavity temperature and interrupted the heating circuit.

Requires Professional
4

Faulty main control board

The PCB relay or triac driving the heating element has failed in the on state, bypassing temperature regulation entirely.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Switch off at the circuit breaker

    Immediately turn off the dedicated oven circuit breaker. Do not attempt to open the oven door while the cavity is overheating.

    Leave the breaker off for at least 30 minutes to allow the oven to cool before any inspection.

  2. 2

    Allow full cool-down before power-cycle

    Once the oven is fully cool, restore power and check whether F1 reappears at startup without any heating command.

    If F1 appears immediately at power-on, the RTD sensor or control board is likely at fault.

  3. 3

    Test RTD sensor resistance

    With the oven unplugged, disconnect the RTD sensor connector and measure resistance. A healthy Fisher & Paykel oven RTD reads approximately 1,100 Ω at room temperature (about 25°C).

    A shorted RTD will read near 0 Ω; an open RTD will read OL. Either result confirms sensor replacement is required.

    Tools required

When to Call a Professional

Contact a qualified technician if:

  • RTD sensor tests normal, pointing to a stuck element relay on the control board
  • Thermal cutoff fuse has opened and must be located and replaced inside the oven chassis
  • Any repair involving live 240 V wiring or the main control board
