Fisher & Paykel Oven Code F5: Clock and Power Modules Not Communicating

What F5 means

Fisher & Paykel legacy 30-inch wall ovens such as the OS302, OD302, OS301 and OD301, and the OB30DDEPX1, show F5 when a communications error occurred between the clock module and the power module. The two modules lost contact. The display shows the code, and the oven may not heat or start a cycle. The remedy is to check connections and replace the power module if it persists.

Common causes of F5

A loose connector between the clock module and power module
A power module that is not responding
A clock module that has stopped sending
A momentary power disturbance

✓ One safe check you can try

1. Switch the oven off at the breaker for a full minute and back on. 2. Set the clock and run a short bake. 3. If F5 stays away, continue using the oven. 4. If F5 returns, switch off the breaker and call us. Do not remove trim or panels; the connectors are behind live circuits.

! Why to stop there

A communications link problem needs careful checks on connectors and modules.
The area around the modules should not be opened by owners.
We start with the connections, then the power module, and explain each step.
A written price comes first, followed by a 30-day workmanship warranty.

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.

F5F5 questions

Is F5 like F4?

They are related. F4 is a problem in the power module itself, while F5 means the clock and power modules cannot talk to each other. Both can end with a new power module.

Will a reset help?

It may restore the link for a while. If the connection is loose or the module is failing, F5 will return, and it is better to repair it than to rely on resets.

Should I cook while F5 is on the display?

No. With the modules not communicating, the oven cannot control heating reliably, so wait for the repair. Switch the breaker off so the oven rests safely.
