Safety: Unplug the wine cooler. Fan blades and evaporator fins are sharp.

Steps:

Access interior fan: Remove shelves and the interior rear panel to expose the evaporator fan assembly.
Inspect for obstructions: Check for ice buildup around the fan, loose wires, or insulation blocking the blades. Clear any obstructions carefully.
Spin test: Gently spin the fan by hand. It should rotate freely without grinding or sticking. If it is stiff or seized, the motor is likely bad.
Check wiring: Follow the fan wires to the connector. Ensure it is fully seated and not corroded or burnt.
Test fan motor: With the unit unplugged, you can measure resistance across the fan motor leads. An open circuit indicates a failed motor. (Do not apply direct mains voltage unless you are trained and the fan is rated for it.)
Replace evaporator fan motor: Remove mounting screws, transfer any brackets or grommets to the new motor, and reinstall. Ensure blades are correctly oriented and not rubbing on the shroud.
Control board: If a known-good fan does not run and E7 persists, the main control board's fan output may be defective and require replacement.

Display shows E7 and interior fan may not run or runs erratically.
