Fisher & Paykel Oven Code F2 04: Clock Board Not Answering the Power Board

What F2 04 means

On current Fisher & Paykel OB24 and OB30 Series 7 and 9 built-in ovens such as the OB30DDPTDX1 and OB24SDPTX1, F2 04 is a communication error reported by the power board. The clock board does not respond in time, or does not respond at all. The display shows the code, and the oven can stop heating because the two boards have lost contact.

Common causes of F2 04

A loose or damaged cable between the power board and clock board
A clock board that has stopped responding
A power board that does not receive the reply
A brief power interruption during a cycle

✓ One safe check you can try

1. Turn the oven off at the breaker for one minute and restore it. 2. Set the clock and try a short bake. 3. Note whether F2 04 appears right away or after the oven warms up. 4. If it returns, switch off the breaker and call us. Please leave the control housing closed.

! Why to stop there

A lost link between boards can be the cable or either board, and only testing tells which.
The connection sits in a housing with mains-connected circuits.
We test first so we replace only what is needed.
You get a written price in advance 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.

F2 04F2 04 questions

Is F2 04 the mirror of F1 04?

Yes. F1 04 means the clock board cannot get an answer from the power board. F2 04 means the power board cannot get an answer from the clock board.

The display still works. Why the error?

A working display only shows the clock board is alive. The reply path to the power board can still be failing, which is why the error can appear with a lit panel.

Can I use the oven in between?

Only if it starts and runs normally after a reset. If the code appears again, it is wiser to stop using it until we have checked the link.
