Step-by-Step DIY Fix Guide
- SAFETY: Disconnect power before inspecting this appliance.
- Switch the oven off at the wall immediately.
- Do not use the oven again until it has been inspected by a technician.
- Contact Fisher & Paykel service — this fault requires professional diagnosis of the sensor, control board, and thermal limiter.
If the warning comes back after restart
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
What This Error Means
The oven cavity has exceeded 305 °C (581 °F) during normal cooking — outside the self-clean mode. This indicates the temperature control system has failed and the oven cannot regulate heat properly. The oven will shut down for safety.
Most Likely Cause by Symptom
The Fisher & Paykel oven may stop, pause, or refuse to complete the cycle normally.
Likely cause: Failed temperature sensor - If the NTC probe reads too low, the control board keeps heating well past the set temperature.
Check first: SAFETY: Disconnect power before inspecting this appliance.
Common Causes
- Failed temperature sensor - If the NTC probe reads too low, the control board keeps heating well past the set temperature.
- Relay stuck closed on control board - A welded relay allows the heating element to run continuously without the board being able to switch it off.
- Faulty thermostat - A defective thermal limiter fails to cut power at the design temperature.

This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
How to Prevent It Recurring
- Have the oven serviced if it ever feels hotter than expected or if food consistently overcooks at normal settings — these can be early warning signs of a failing sensor.
Related Error Codes
F2
During a pyrolytic self-cleaning cycle, the oven cavity temperature has exceeded safe limits. The oven will lock the door and halt the cycle automatically. This is a safety cut-out — do not attempt to force the door open.
C1
The oven cavity temperature has exceeded 305 °C (581 °F) outside of a self-clean cycle. C1 is a critical safety cut-out — the oven will switch all heating off immediately and lock out further operation until the fault is cleared by a technician.
