Gorenje Outdoor Coil Frosting / Defrost Malfunction

Outdoor unit coil becomes heavily iced over in heating mode and heating performance drops.

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

Normal frost with insufficient defrost, Faulty defrost sensor, Dirty outdoor coil, Low refrigerant charge

Steps:

Observe defrost: In cold, humid weather, some frost is normal. The unit should periodically enter defrost mode to clear ice.
Clean coil: Turn off power and gently clean the outdoor coil to improve heat exchange.
Clear drainage: Ensure melt water can drain away and is not refreezing around the base.
Persistent heavy ice: If the coil remains encased in ice and heating is poor, a technician should check defrost sensors, control logic, and refrigerant charge.
