Wine Enthusiast wine cooler displays E8 and interior light or fans may not operate correctly.

Safety: Unplug the cooler before removing the rear or top panels. High voltage is present on the power input side.

• Check outlet and cord: Verify the wall outlet has correct voltage and the power cord is not damaged. Try a different outlet if necessary.
• Inspect internal connections: Remove the rear access panel and locate the main control board. Check that the AC input wires are firmly attached and that there are no burnt spots on the board.
• Disconnect low-voltage loads: With power disconnected, unplug non-essential loads (LED light harness, fans) from the board. Reconnect power briefly to see if E8 clears, indicating a shorted accessory.
• Check for blown fuses: Some Wine Enthusiast boards have small onboard fuses. Inspect and test with a multimeter; replace only with identical type and rating.
• Replace failed components: If the board shows visible damage or no low-voltage output, replace the main control board with a compatible Wine Enthusiast part.

Because this involves mains voltage and board-level power supplies, professional service is recommended if you are not experienced with electrical safety.
