Possible Causes
Failed compressor relay or triac on PCB, open compressor winding, failed thermoelectric (Peltier) module on some models, wiring fault
How to Fix / Troubleshooting
Safety: Unplug the appliance before working on the compressor or cooling module. High voltage and hot surfaces may be present.
Steps to address F4:
- Identify cooling type: Determine if your Danby unit uses a traditional compressor or a thermoelectric (Peltier) module.
- Compressor models: Access the rear compartment, inspect the start relay and wiring. Test compressor windings for continuity and shorts to ground. Replace the start relay or compressor as needed (compressor replacement should be done by a refrigeration technician).
- Thermoelectric models: Access the cooling module, inspect for burnt connectors or cracked modules. Test the module for proper resistance and replace if open or shorted.
- Control PCB: If the cooling hardware tests good but F4 persists, the control PCB may have a failed output device and should be replaced.
