Fisher & Paykel oven Error Code C1: Oven Temperature Exceeded Maximum Safe Limit

1. SAFETY: Disconnect power before inspecting this appliance.
2. Switch the oven off at the wall immediately — do not attempt to clear C1 by power-cycling.
3. Allow the oven to cool completely with the kitchen ventilated.
4. Contact Fisher & Paykel service. Quote error code C1 — they will prioritise it as a safety fault.
5. Do not use the oven until a qualified technician has inspected and repaired it.

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.

Fisher & Paykel oven warnings like this often appear after interrupted heating, control resets, sensor mismatch, or a fault that returns during warm-up rather than during a stable cook cycle.

• Assuming the display code proves one exact failed part before the safe first checks are done.
• Replacing a lock or latch too early when alignment, trapped laundry, or startup conditions may still explain the warning.
• Treating a sensor-related warning as a guaranteed board failure before checking the simpler model-family causes first.

• Temperature sensor failure - A failed NTC probe sends an inaccurate low reading, causing the control board to overheat the cavity.
• Control board relay failure - A stuck relay allows an element to run continuously with no off cycles.
• Thermal limiter failure - The backup thermal cut-out has not operated as designed.

• Annual inspection by a qualified technician can catch failing sensors before they cause overtemperature events.

If the same warning returns after the first safe checks, or the next step would require invasive disassembly, stop there and move to model-specific guidance or service.
