How to Fix / Troubleshooting
Warning: Disconnect power before accessing the ice room fan.
- Access ice room: Remove the ice bucket and any covers to expose the ice room fan housing.
- Inspect for ice: Look for frost or ice blocking the fan intake or blades. Defrost gently with a hair dryer if needed.
- Check fan movement: Spin the fan blade by hand; it should move freely. Inspect for cracks or obstructions.
- Inspect wiring: Verify the fan connector is secure and wires are not pinched in the door.
- Replace fan motor: If the fan is seized or tests open on a multimeter, replace with a Samsung-compatible ice room fan motor. Remove mounting screws, swap the motor, and reconnect.
- Reassemble and test: Refit covers, restore power, and confirm the fan runs during ice production. If 40E persists, the PCB or door harness may require professional diagnosis.
