Whirlpool Refrigerator: coils freezing
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.
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
DIY Solutions
Perform manual defrost
- Unplug the refrigerator or turn it off.
- Remove contents and leave doors open to allow ice to melt naturally or use pans of warm (not boiling) water to speed melting.
- Dry interior and restart refrigerator after all ice has melted.
Check and reseat/replace door gasket
- Inspect gasket for cracks or gaps.
- Clean gasket with warm, soapy water.
- Replace gasket if worn or damaged.

Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Defrost Thermostat
Monitors evaporator temperature and opens the defrost-heater circuit at a safe temperature.
- Typical part-only price
- $15 - $45
- DIY difficulty
- Medium
- Estimated time
- 30-60 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Defrost Heater
Melts frost buildup on the evaporator coils during the defrost cycle.
Defrost Timer
Controls the cooling cycle and switches the appliance into defrost mode automatically.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.

Common Issues Reported by Users
- Defective defrost thermostat preventing proper defrost cycle
- Blocked air flow due to dirty condenser coils
- Faulty evaporator fan motor not circulating air properly
User Suggested Solutions
-
Check and clean the condenser coils. Unplug the refrigerator, locate the coils, and use a vacuum or brush to remove dust and debris. Plug it back in and monitor for changes.
-
Test the defrost thermostat. Use a multimeter to check for continuity. If defective, replace it. Ensure the refrigerator is unplugged during this process.
-
Inspect and replace the evaporator fan motor if it's not working. This may require removing the back panel of the freezer to access the fan.
