Wine cooler shows E8 and interior lights or display may flicker or go out intermittently

Safety: Always unplug the unit before accessing the control board. Do not attempt live-voltage testing unless you are trained and equipped.

E8 often indicates a low-voltage or power regulation problem inside the wine cooler.

• Step 1 – Check external power: Plug the wine cooler directly into a dedicated wall outlet (no extension cords or power strips). Verify the outlet is properly grounded and not shared with heavy loads.
• Step 2 – Inspect power cord: Examine the cord for cuts, kinks, or burn marks. Replace the cord set if damaged.
• Step 3 – Access control board: Remove the rear upper or lower panel (depending on model) to expose the main control board. Look for burnt components, swollen capacitors, or darkened areas.
• Step 4 – Reseat connectors: Gently disconnect and reconnect the low-voltage harnesses from the board to the display, lights, and fans to ensure solid contact.
• Step 5 – Replace control board: If visual inspection shows damage or E8 persists after verifying external power and connections, replace the main control board with a KitchenAid-specified part. Transfer any jumpers or programming plugs as instructed in the service documentation.
