Error codeWon’t Heat
ApplianceOven
Quick answer
The oven will not heat or remains cool during a cooking cycle.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so Won’t Heat may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means

Self-clean can affect lock/cool-down behavior.
The condition may be tied to a specific cooking mode.
The oven may stop heating or overheat.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.

When to call a technician
Stop using the oven for uncontrolled overheating, smoke, a burning electrical smell, repeated breaker trips, or a self-clean door/lock condition that does not resolve after safe cool-down.
Seeing this code on your Fisher & Paykel appliance?
Book a specialist visit for a clear estimate and approval before any repair.
No. The old Fisher record identifies the condition described above, but it does not by itself prove which component has failed. Diagnosis should confirm the cause on the exact model.
Only when the appliance is otherwise safe and the model guidance permits it. A single controlled restart can help separate a transient state from a returning fault, but repeated resets are not a repair for **Won’t Heat**.
Provide the full model number, the exact code or symptom, what the appliance was doing when it appeared, and whether the condition returned after any safe owner-level check.
