Wine cooler displays E6 and interior fan does not run or runs erratically, causing uneven temperatures.

Safety: Disconnect power before accessing the interior fan. Fan blades and metal edges can be sharp.

Steps to address E6:

• Visual check: Open the door and listen for the fan when the compressor is running. If silent, remove shelves and the rear interior panel to access the evaporator fan.
• Inspect for obstructions: Look for ice buildup around the fan shroud or foreign objects that may block the blades. Carefully remove ice with warm water and a cloth; do not use sharp tools.
• Spin the fan by hand: With power off, gently rotate the fan blades. They should spin freely without grinding. Stiff or seized movement indicates a bad motor.
• Check wiring: Ensure the fan connector is fully seated and wires are not pinched or cut.
• Test the fan motor: If you have a multimeter, measure resistance across the fan motor terminals. An open circuit indicates a failed motor. Some DC fans may require voltage testing, which should only be done by experienced users.
• Replace the fan motor: Order a compatible SMEG evaporator fan motor assembly. Transfer the fan blade if it is separate, and reinstall the motor with original screws and vibration grommets.
• Control board check: If a known-good fan does not run and wiring is intact, the main control PCB may not be supplying power. PCB replacement is recommended via a professional.

Tip: After repair, ensure the rear panel is reinstalled correctly; missing or misaligned panels can disrupt airflow and cooling performance.
