Wine cooler shows E8; unit may be completely unresponsive or may power on and off unexpectedly.

Safety: Unplug the wine cooler and wait several minutes before accessing the control board. Capacitors on the board may hold a charge briefly.

Steps to address E8:

• Check power source: Verify the outlet has correct voltage using a plug-in tester or multimeter. Avoid using lightweight extension cords or power strips.
• Inspect power cord: Look for cuts, burns, or crushed sections on the Kenmore power cord. Replace the cord if damaged.
• Access the main control board: On many Kenmore wine coolers, the main PCB is located at the rear behind a metal or plastic cover. Remove the cover screws to expose the board.
• Visual inspection: Look for burned components, bulging capacitors, or darkened areas on the PCB. Check for loose connectors or broken solder joints at high-current terminals.
• Reseat connectors: Disconnect and reconnect all harness plugs to ensure solid contact. Do not force connectors; align them carefully.
• Replace the board if damaged: If there is visible damage or E8 persists after reseating, replace the main control board (PCB) with the correct part number for your Kenmore model. Transfer any jumpers or configuration plugs from the old board to the new one as instructed.
• Reassemble and test: Reinstall the cover, restore power, and verify that the display initializes normally and E8 is cleared.

Note: Board-level repairs (soldering components) are not recommended for most homeowners; replacing the entire board is the standard approach.
