How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing the fan or wiring.
- Check for obstructions: Remove drawers and inspect the rear panel area for ice or packaging blocking the fan.
- Defrost if iced: If ice is present around the fan, perform a full manual defrost (12–24 hours unplugged) and then test again.
- Access fan assembly: Remove the inner rear panel to expose the fan. Spin the blades by hand to ensure they move freely.
- Inspect wiring: Check the fan connector and wires for damage, especially the thin tachometer wire (often a third wire on DC fans).
- Replace fan motor: If the fan does not run or F3 persists, install a new Balay evaporator fan motor with tachometer.
If a new fan does not resolve the error, the main control board may not be reading the tach signal correctly and should be checked by a technician.
