Gladiator Defrost System Failure

Freezer coils (evaporator) are completely encased in ice, and airflow is blocked.

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

Open defrost heater, Failed defrost thermostat, Defective control board defrost timer, Broken defrost wiring

Safety First: Unplug the freezer before defrosting or testing components. Avoid using sharp tools on coils.

Step 1 – Manual defrost: Remove food and allow all ice to melt. Use towels to collect water.
Step 2 – Test defrost heater and thermostat: Access the evaporator area and check continuity of the defrost heater and defrost thermostat. Replace any open components.
Step 3 – Check control board: If heater and thermostat are good, the electronic control board may not be initiating defrost and should be replaced.
