Ikea Cabinet Condensation / Mullion Heater Issue

Condensation or moisture forming on the outside of the freezer cabinet or around the door gasket.

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

High room humidity, Door gasket leaking, Internal mullion heater not operating (on some models), Frequent door openings

Safety: Unplug before accessing any heater wiring.

Steps:

1. Reduce humidity: Use a dehumidifier in very damp rooms and avoid placing the freezer near open water sources.
2. Check gasket seal: Repair or replace a leaking gasket.
3. Mullion heater (if fitted): Some IKEA freezers have a small heater around the door frame. If condensation is heavy only around the frame, the heater may have failed. Access and test for continuity; replace if open.
4. Usage habits: Minimize door opening time to reduce moisture ingress.
