Refrigerator Not Defrosting
Common causes, what you can check yourself, and when to call a professional — a practical guide for New York homeowners and property managers.
Most likely causes
When we get service calls in Brooklyn and Manhattan for this issue, one of these is almost always the culprit:
- Failed defrost heater
- Failed defrost thermostat or bimetal
- Faulty defrost timer or control board
- Blocked drain causing refreeze
What to check before calling a professional
Work through these in order. If none resolves the problem, it's time to schedule service.
- Look for a thick sheet of frost on the back freezer wall — the signature symptom
- Force a manual defrost by unplugging for 24 hours with the doors open — if cooling returns, the defrost circuit is confirmed bad
- Check the model's diagnostic mode for defrost-cycle codes
