Maytag Oven/Range F9 Error Code
The oven temperature has exceeded the maximum safe limit, often due to a stuck relay or sensor failure.
Common causes
- Shorted oven temperature sensor
- Faulty control board with stuck relay
- Wiring short causing constant heat
How to fix it
- Immediately turn off the range at the circuit breaker to prevent fire hazard.
- After cooldown, restore power and check if error returns.
- Test the oven temperature sensor resistance (should be ~1100 ohms at room temp).
- If sensor is shorted, replace it.
⚠ When to call a pro: Do not operate the oven until the issue is resolved. If the sensor tests good, the control board may be faulty.
