Possible Causes

How to Fix / Troubleshooting
Safety: Disconnect mains power before accessing fans.
Steps:
- 1. Listen and feel for airflow: With the unit running (door switch pressed), check for airflow from vents in the fridge and freezer. Weak or no airflow indicates fan issues.
- 2. Access the fan: Remove the relevant inner panel (freezer or fridge) to expose the fan assembly.
- 3. Inspect and clean: Remove any ice, dust, or debris from the fan blades and housing. Ensure blades spin freely.
- 4. Check connectors: Reseat the fan connector and inspect for corrosion or loose pins.
- 5. Replace fan: If the fan does not run when powered or gives F3 despite clear wiring, replace the fan motor assembly.
- 6. Board diagnosis: If a new fan does not resolve F3, the control board may not be reading the tach signal correctly and should be replaced by a technician.
