Freezer temperature acceptable but ice builds up heavily on rear wall or around drawers.

Safety first: Unplug the appliance before accessing the evaporator area.

Manual defrost:

• Remove all food from the freezer and store in a cool box if possible.
• Leave the doors open and allow all ice to melt naturally. Place towels to catch water.

Inspect defrost system:

• Remove the rear interior panel to expose the evaporator and defrost heater.
• Check the heater for visible damage and inspect the defrost thermostat/thermal fuse clipped to the evaporator.
• Ensure wiring and connectors are intact.

Replace faulty parts:

• If the heater is open-circuit or physically damaged, replace with a Finlux defrost heater assembly.
• If the defrost thermostat or fuse is open at room temperature, replace with the correct Finlux-rated part.

Check door seals:

• Inspect the freezer door gasket for gaps or tears that could allow moist air in.
• Clean and reshape or replace the gasket as needed.

Reassemble and test: Restore power and monitor frost buildup over the next 1–2 weeks.
