Excessive frost or ice buildup on the back wall or around the evaporator inside the wine cooler.

Safety first: Unplug the appliance before defrosting or accessing internal components.

Steps to address frost buildup:

• Manual defrost: Turn off the cooler, open the door, and allow all ice to melt naturally. Place towels to catch water. Do not use sharp tools.
• Inspect door gasket: Check for tears, gaps, or hardened sections. Replace the door gasket if it does not seal evenly.
• Check defrost components: After defrosting, access the evaporator area and test the defrost heater and sensor as described in defrost error procedures.

If frost returns quickly, the defrost system or gasket must be repaired or replaced. Complex defrost control faults should be handled by a technician.
