Wine cooler displays E7 and the condenser fan at the rear may not run, causing overheating.

Safety first: Disconnect power and pull the wine cooler away from the wall before removing the rear service panel. Beware of sharp metal edges and hot components.

Steps to troubleshoot:

• 1. Inspect airflow: Ensure there is adequate clearance around the rear and sides of the unit per Viking installation specs. Poor ventilation can overheat the condenser area.
• 2. Access condenser fan: Remove the lower rear panel to expose the condenser coil and fan assembly.
• 3. Clean the condenser area: Use a soft brush and vacuum to remove dust from the condenser coil and fan blades. Do not bend the coil fins.
• 4. Check fan movement: Spin the fan blades by hand. If stiff or seized, the motor is likely failing. Check for cable ties or debris obstructing the blades.
• 5. Inspect wiring: Verify the fan connector is fully seated and wires are not cut or pinched. Repair any damaged wiring.
• 6. Test fan motor: With power disconnected, measure resistance across the motor leads. An open circuit indicates a failed motor. If you have the skills, you can also verify correct voltage from the control board when the unit calls for cooling.
• 7. Replace fan motor if needed: Remove mounting screws, transfer any brackets, and install the new motor. Ensure blades are correctly positioned and not rubbing.
• 8. Control board evaluation: If the fan motor is good but never receives power, the main control board may be defective and should be replaced by a technician.

After repair: Reinstall the rear panel, restore power, and confirm the condenser fan runs during compressor operation and that E7 clears.
