Wine cooler displays EC26 and may show issues with door status; interior lights or fans may not behave correctly.

Safety first: Disconnect power before removing trim or switch assemblies.

Step 1 – Check door switch behavior

• Open and close the door while observing the interior lights and fan operation.
• If lights stay on with the door closed or never come on, the door switch circuit may be faulty.

Step 2 – Inspect door gasket and alignment

• Ensure the door closes squarely and fully against the cabinet.
• Check that the door magnet (if used) is present and aligned with the switch location.

Step 3 – Locate and test door switch

• Depending on model, the switch may be in the cabinet frame or integrated into the hinge area.
• Remove the switch or trim cover and inspect wiring for damage.
• Reseat the connector and test operation again.

Step 4 – Replace door switch

• If the switch is physically damaged or does not change state when the door is opened/closed, replace it with the correct Sub‑Zero door switch.

Step 5 – Control board check

• If a new switch does not resolve EC26, the main control board input may be defective and require professional service.
