Whirlpool Refrigerator: coils freezing

Professional Repair Guide

What is this symptom?

If you notice excessive frost or ice buildup on the evaporator coils of your Whirlpool refrigerator, it could indicate a problem affecting cooling efficiency and airflow. This issue can stem from a faulty defrost system, blocked airflow, or a door gasket leak, leading to potential food spoilage and higher energy bills.

Urgency: Medium

Important Tips for Whirlpool Models

  • Certain Whirlpool refrigerator models were subject to a class‑action settlement due to excessive frost buildup on evaporator coils as a defect.

Possible Causes

Faulty or non‑operational defrost system (defrost heater/thermostat/timer)

How to Identify: Repeated frost buildup on evaporator coils, no automatic defrost cycles detected

Part: Defrost heater, defrost thermostat, defrost timer/control board

Blocked airflow due to frost and airflow obstruction

How to Identify: Visible ice on coils reaching into airflow paths, poor cooling performance despite running system

Part: Evaporator coils, cabinet airflow paths

Door gasket leakage or frequent door openings

How to Identify: Moisture or frost near door edges, inconsistent cooling, temperature fluctuations

Part: Door gasket

Whirlpool manufacturing defect in certain models causing excessive frost buildup

How to Identify: Model affected is from specific serial ranges with reports of frost buildup impairing cooling

Part: Evaporator coil assembly
