KitchenAid Oven/Range F9 Error Code
The oven temperature has exceeded the safe limit.
Common causes
- Shorted oven temperature sensor
- Main control board failure (relay stuck)
- Oven heating element stuck on
How to fix it
- Immediately turn off the range at the circuit breaker.
- Allow the oven to cool completely.
- Inspect the oven temperature sensor for damage or shorts (test resistance).
- If sensor is shorted (near 0 ohms), replace it.
- If sensor is okay, the control board likely needs replacement.
⚠ When to call a pro: Do not use the oven until repaired; call a technician if sensor replacement does not fix it.
