What the Error Code Means
Error code F9 generally means the oven is not reaching the target temperature in the expected time.
It points to a heating performance condition rather than a confirmed single failure.
Common Symptoms You May Notice
- The oven takes much longer to preheat or never reaches the set temperature.
- The display shows F9 and the oven may beep.
- Cooking results are uneven or undercooked.
Most Common Causes (From Least to Most Serious)
- Oven door was opened during preheat: Opening the door can drop heat quickly and delay reaching the target temperature.
- Extended use at high temperatures: Long bake or broil times can affect how quickly the oven stabilizes at the set temperature.
- Heating performance is outside the expected range: In some cases the oven pauses when it cannot confirm normal heating behavior.
Safe Things You Can Check Yourself
- Turn the oven off and allow it to cool completely before restarting.
- Try preheating again with the door closed to see if the code clears.
- Power cycle the oven: turn it off at the control panel, wait one minute, and turn it back on.
If at any point this feels unsafe or unclear, stop and contact a professional.
When to Stop and Call for Service
- The F9 code returns after cooling and a reset.
- The oven will not heat at all or shuts down repeatedly.
- You notice smoke, burning smells, or unusual heat.
Typical Repair Cost Range
$150-$450 is typical for professional diagnosis and repair of oven heating issues, depending on the cause and parts involved.
