Fisher & Paykel Oven Code F3: Cavity Over 600 F in Normal Cooking

What F3 means

On Fisher & Paykel legacy 30-inch wall ovens such as the OS302, OD302, OS301 and OD301, and the OB30DDEPX1, F3 means excessive cavity temperature. The oven temperature was sensed at over 600 F (315 C) during normal cooking operation. The display shows F3 and the oven stops heating to protect itself. The cavity is far hotter than what you selected, and the cooking is interrupted. The oven stays off until it cools.

Common causes of F3

A temperature sensor reading wrongly, or a control that overshoots
A heating element that stays on without control
A relay on the power module that sticks closed
A cavity that cannot shed heat because of blocked airflow

✓ One safe check you can try

1. Turn the oven off and let it cool completely with the door closed. 2. Check that nothing is stored in the oven or blocking its vents. 3. Switch the breaker off for a minute and back on. 4. Try a bake at 350 F for a short time. 5. If F3 returns, stop using the oven and call us.

! Why to stop there

An oven that heats beyond 600 F in normal cooking is a safety concern.
Whether the sensor, relay or element is responsible needs testing.
We do not recommend repeated tries while the cause is unknown.
You get a written price first, and a 30-day workmanship warranty on the repair.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F3F3 questions

Is 600 F ever normal?

In normal cooking, no. Self clean runs hotter, but regular bake and broil stay well below that. F3 means the oven went far beyond what you set.

Is it a sensor or a heating problem?

Either can cause it. A sensor that under-reads makes the control keep heating, while a stuck relay heats regardless. We test both before replacing anything.

What should I do if I smell burning?

Turn off the oven at the breaker, keep the door closed, and open windows. Do not use it again until we have inspected it. A burning smell can mean something inside is overheating.
