Wolf Evaporator Frost / Defrost Failure

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

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Defective defrost heater, Failed defrost thermostat, Blocked drain causing ice accumulation, Door gasket leak allowing moist air in

Safety: Unplug the unit and protect the floor from water.

Manual defrost: Leave the door open and allow all ice to melt. Use towels to absorb water. Do not use sharp tools to remove ice.
Clear drain: Locate the drain hole under the evaporator and clear it with warm water and a flexible brush or pipe cleaner.
Inspect gasket: Check for tears or gaps in the door gasket and repair or replace as needed.
If frost returns quickly: Test the defrost heater and thermostat with a multimeter and replace any failed components.
