What this code means
Summary for F2 21 (OB60 built-in oven — service diagnostic codes). Independent repair notes only — not a substitute for the current Product Help article or tech sheet for your serial.
Symptoms you may notice
- This is a technician / service-mode diagnostic reading for the OB60 built-in oven range, not typically seen during everyday use.
- If F2 21 is visible during ordinary operation, the oven may be behaving abnormally (failing to heat, stopping mid-cycle, or repeating a fault).
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
- Do not attempt to enter or interpret the service/diagnostic mode yourself.
- Allow the oven to cool fully before doing anything else.
- Note when and how F2 21 appeared (which function, what stage of cooking) for the technician.
- Switch the appliance off at the wall or breaker if it is behaving unsafely, and avoid further use until it has been checked.
- Record the full model and serial number from the rating plate.
Important safety warning. Service/diagnostic codes are for trained technicians using official test procedures. Do not open panels, access heating elements or wiring, or attempt to force the oven into a diagnostic mode. If you ever smell gas, stop immediately, leave the area, and contact your gas provider and a qualified technician. If you notice smoke, sparks, or a burning smell, disconnect power at the wall if safe to do so and call a professional immediately.
When to call a technician
Service/diagnostic codes like F2 21 need trained interpretation. Book an independent technician via Fisher & Paykel Appliance Repair rather than opening panels.
