Possible Causes

Firmware error in main PCB, Multiple sensor faults detected, Corrupted EEPROM on control board, Incorrect voltage or power surge damage

How to Fix / Troubleshooting

Safety: Unplug the unit before any internal inspection.

Basic user actions:

  • Power reset: Disconnect power for at least 10 minutes to allow capacitors to discharge and the control to fully reset.
  • Check power quality: Plug the cooler directly into a grounded wall outlet. Avoid surge-prone extension cords.

If Er persists:

  • Inspect the main control board for visible damage (burn marks, swollen components).
  • Check all sensor connections (cabinet, evaporator, ambient) for secure fit.
  • If no obvious wiring issues are found, the main control board is likely faulty and should be replaced with a BODEGA43-compatible PCB.
