What this code means
The control is not seeing the expected cooling-fan speed. F8E0 and F8E1 concern low-speed operation; F8E2 and F8E3 concern high-speed operation. “Underspeed” means too slow, while “overspeed” means faster feedback than expected.
Most likely causes
- A cooling fan is obstructed, worn or failing
- The fan Hall-effect speed sensor is not reporting correctly
- A loose connector or damaged fan harness
- A control-board drive or feedback fault
- Restricted airflow around the built-in oven
Safe checks for the owner
- Stop using the oven if the control area becomes hot or the fan makes grinding, scraping or surging sounds.
- Confirm visible exterior vents are not blocked.
- Do not operate the oven outside the cabinet or bypass the fan circuit.
Estimated U.S. repair cost
$300–$650, depending on model, access, parts availability and local labor.
