Symptoms
- A letter/number code on the display
- Unit stops running when the code shows
- Beeping with the code
- Code returns after resetting
Likely causes
- CommonFull bucket or bucket not seated (often 'FL' or similar)The most common code; check the bucket first.
- CommonFrost or defrost sensor codeThe unit detected icing and paused to protect the coil.
- PossibleHumidity or temperature sensor faultA sensor reading out of range can trigger a protective code.
- Less commonControl board communication errorAn internal wiring or board fault, often needing service.
What to do
- Check the manual or manufacturer's site for what the specific code means for that model.
- Empty and reseat the bucket fully, even if it looks like it's already in place.
- Unplug the unit for a few minutes to fully reset the control board, then restart.
- If it's a frost-related code, let the unit sit off for a few hours to fully thaw before restarting.
- Note whether the code appears immediately or after some run time, which helps narrow down the cause.
- If the code returns after a full reset with an empty, well-seated bucket, the unit likely needs service.
Tools and parts
