Heavy ice around the evaporator area was blocking airflow and preventing normal temperature control.
| Appliance | Refrigerator / freezer |
|---|---|
| Customer complaint | Fresh-food section warm, frost or ice visible |
| Diagnostic finding | Evaporator airflow restricted by heavy frost buildup |
| Outcome | Defrost system, fan, drain, and sensor circuit evaluated |
Why the refrigerator can feel warm
Cold air is produced at the evaporator and circulated by a fan. When the coil becomes encased in ice, air cannot move through the passages even though the compressor may continue running.
Possible causes
The root cause can be a failed defrost heater, open defrost thermostat, faulty thermistor, control-board problem, weak evaporator fan, blocked drain, or an air leak that introduces excess moisture.
Why manual defrost is temporary
Unplugging the refrigerator long enough to melt the ice may restore cooling briefly, but the frost will return unless the failed component or airflow problem is corrected.
