Denys Mitchell Key Takeaways
- Dirty condenser coils are the most overlooked cause of poor cooling and take five minutes to fix.
- A failed defrost heater causes ice to build up on the evaporator, blocking airflow to the fresh food section.
- Evaporator and condenser fan motors are easy to test and replace if airflow feels weak from the vents.
- Compressor issues require a technician — but condenser coil cleaning should always come first.
- WRF and WRS models have accessible coils at the bottom front behind the kick plate on most configurations.
The Bottom Line
Most Whirlpool refrigerator cooling failures are caused by dirty coils, a defrost system fault, or a failed fan motor — not the compressor. Start with the inexpensive checks before assuming a costly repair.
When your whirlpool refrigerator not cooling becomes a problem, this guide walks you through the most likely causes and how to fix them.
A Whirlpool refrigerator that isn't keeping food cold puts hundreds of dollars of groceries at risk. Before assuming the worst, work through this guide. The majority of cooling failures on WRF and WRS models trace back to airflow restrictions or defrost system faults — both far cheaper to address than a compressor replacement.
Step 1 — Clean the Condenser Coils
Condenser coils dissipate heat from the refrigerant. When they're coated in dust and pet hair, heat can't escape efficiently and the compressor works overtime — driving up temperatures inside the cabinet. On most WRF and WRS models, the coils are located at the bottom front behind the kick plate or at the back of the unit.
Pull the kick plate or move the unit away from the wall, and use a coil brush or vacuum with a brush attachment to remove all debris. This single maintenance step resolves a significant percentage of "not cooling" complaints and should be done every 6 to 12 months. On WRS325SDHZ and WRF555SDFZ models, the front-bottom coil location makes this a five-minute task.
Step 2 — Check for Defrost System Failure
Frost-free Whirlpool refrigerators run a defrost cycle every 8 to 12 hours to melt ice off the evaporator coils. If the defrost heater, defrost thermostat, or defrost timer fails, ice accumulates on the evaporator until it completely blocks airflow. The symptom is a fresh food section that's warm while the freezer remains cold — the freezer is still being cooled by the compressor, but the air can't circulate to the refrigerator compartment.
You can confirm this by removing the rear panel inside the freezer to inspect the evaporator coils. A solid block of ice is a definitive defrost system failure. The defrost heater and thermostat can each be tested with a multimeter and cost from $25 to replace.
Diagnostic Quick-Reference Table
| Symptom | Likely Cause | DIY Fix? | Est. Cost |
|---|---|---|---|
| Both sections warm, compressor running hot | Dirty condenser coils | Yes | $0 |
| Fridge warm, freezer cold, ice on back wall | Defrost heater or thermostat | Yes | from $25 |
| Warm throughout, compressor not running | Start relay or compressor | Start relay: Yes | from $15 |
| Loud fan noise, poor cooling | Evaporator fan motor iced or failed | Yes | from $40 |
| Condenser fan not spinning | Condenser fan motor | Yes | from $50 |
| Clicking sound, compressor won't start | Start relay | Yes | from $15 |
| Compressor confirmed failed | Compressor | No — technician | from $500 |
Step 3 — Test the Evaporator and Condenser Fan Motors
The evaporator fan circulates cold air from the freezer into the fresh food section. If it's iced over or the motor has failed, the refrigerator compartment won't receive cold air even if the freezer is working properly. Open the freezer door, press the door switch manually, and listen for the fan. No sound or loud rattling points to a motor or ice obstruction. Evaporator fan motors for WRF and WRS models cost from $40.
The condenser fan draws air across the condenser coils at the bottom or back of the unit. If this fan isn't running, the compressor will overheat and shut down. Test the motor with a multimeter and replace if it reads open — condenser fan motors cost from $50.
Start Relay — Quick Compressor Test
If the compressor isn't running at all, don't assume it's failed. The start relay — a small component that plugs onto the compressor — is a common failure point. Pull the relay off and shake it; a rattling sound inside indicates it's failed. Replacement relays for Whirlpool refrigerators cost from $15 and take two minutes to replace. This simple check has saved many owners from an unnecessary compressor diagnosis call.
