What this code means
The oven control modules are no longer exchanging valid data. F6E0 is a user-interface communication fault; F6E6 applies to the main or upper appliance manager; F6E9 applies to the lower appliance manager.
Most likely causes
- A loose low-voltage communication connector
- A pinched, broken or heat-damaged harness
- A failed user interface
- A failed upper or lower appliance manager
- Unstable low-voltage power from a control module
Safe checks for the owner
- Disconnect power at the breaker for five minutes and retry once.
- Record which cavity and functions remain available after the reset.
- Stop using the oven if the display restarts repeatedly or heating commands become unpredictable.
Estimated U.S. repair cost
$220–$500, depending on model, access, parts availability and local labor.
