The defrost heater melts frost off the evaporator during the defrost cycle. If it fails, ice builds up, airflow stops and the freezer warms.
Appliance part
Freezer Door Gasket
The gasket seals the door against the cabinet.
A hardened or torn seal lets warm, humid air in, which causes frost, constant running and condensation
Test with a dollar bill: it should drag when pulled out.
Symptoms of a failed freezer door gasket
- Frost near the door opening
- Freezer runs constantly
- Condensation or ice on the frame
Fitment
Gaskets are model-specific and often ship as a frame assembly; confirm the hinge side and door style.
Before you buy
Confirm the model and serial plate before ordering — two parts can look identical and still not fit. If you would rather not fit it yourself, request a repair quote and we will route it to an independent technician.

The evaporator fan moves cold air from the coil into the cabinet. A failed motor leaves the compressor running but the cabinet warm, and it often makes a bearing noise before it stops.
The start relay gives the compressor a momentary boost to start. When it fails, the compressor clicks, hums briefly and trips, and the cabinet warms.
The ice maker fills, freezes and dumps cubes on a timer. Failures show up as no ice, small or hollow cubes, or a maker that overflows.
The thermostat or thermistor tells the compressor when to run. A failed sensor makes the freezer run constantly or not at all, and the part is inexpensive compared with the compressor it protects.
