Possible Causes
Corrupted main control board memory, Incorrect control board installed, Power surge damage, Failed control board
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing the control board.
EP indicates a problem with the control board's internal programming.
- Power reset: Disconnect power for 10 minutes, then restore. Sometimes the board will recover from a transient error.
- Check model tag: Verify the model number on the rating plate matches the control board part number installed. An incorrect board can cause EP errors.
- Inspect board: Remove the rear access panel and inspect the main control board for burnt components or corrosion.
- Replace board if needed: If EP persists after a reset and wiring is intact, the main control board typically must be replaced. Transfer any jumpers or programming plugs exactly as on the original board.
- Programming: Some Café models require entering a programming code after board replacement. Follow the service manual or tech sheet instructions carefully.
