Fisher & Paykel Current Range Code F2 18: Power Board Oscillator Error

What F2 18 means

Fisher & Paykel OR30SCG6X1, OR36SDG6X1 and RDV3 pro ranges can display F2 18 when the power board reports a crystal oscillator error. That is the timing circuit the board relies on. It can appear during baking when a lot of condensation has built up. The oven may shut off or lock out controls until the board settles. The oven can also shut itself off in the middle of a bake.

Common causes of F2 18

Condensation reaching the power board during a long, moist bake
Failing crystal oscillator on the power board
Intermittent connection to the board after heavy use

✓ One safe check you can try

1. Let the range cool completely with the door slightly open for an hour to dry out the cavity. 2. Wipe away any visible moisture around the control area and door seal. 3. Turn the range off at the breaker for a minute and restore power. 4. If F2 18 comes back on a dry oven, do not bake again; call us.

! Why to stop there

The oscillator is part of the power board, so the fix is a board replacement rather than an adjustment.
Repeated restarts on a failing timing circuit can corrupt oven settings.
We check for moisture sources first, then quote the board in writing before we order it.

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 18F2 18 questions

Could steam from cooking cause F2 18?

Yes. The error can show up during baking with a lot of condensation, so a very moist roast or a blocked vent path is worth mentioning. A dry restart sometimes clears it for good.

Is F2 18 dangerous?

It is a board-level message, not a gas or burn warning. The oven may stop heating, which is the safe response, but we still want the cause found before regular use resumes.

What will the repair involve?

If the error repeats on a dry oven we replace the power board. We give you a written price first and cover our work with a 30-day workmanship warranty.
