Reviewed for clarity on KitchenAid appliances; always match the code to your specific model.
F21 · KitchenAid oven · Oven F-code (model-dependent).
Model compatibility: KitchenAid reuses codes across series and model years, so F21 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
KitchenAid EOC displays may show F21 for oven f-code. Cool the cavity fully, try one breaker reset, then stop if the code returns. If your manual lists a different description for this code, trust the manual over any general summary.
Symptoms you may notice

- F21 appears without an obvious cause
- The oven behaves inconsistently with F21 shown
Possible causes
- A sensor reading out of range
- A wiring or connection issue
- A control interpreting the reading as a fault
