Whirlpool Refrigerator Not Cooling: What to Do

Whirlpool refrigerator is not cooling, you’re not alone — this is one of the most common service calls we get at Wilson & Myers. The good news: most causes are diagnosable, and many can be fixed without replacing the whole appliance. This guide covers every reason your Whirlpool fridge is not cooling, how to identify the cause, and when it’s time to call a pro.
Diagnostic Table for Whirlpool Refrigerator Not Cooling
Start here before doing anything else.
| Symptom | Most Likely Cause | DIY or Pro? |
|---|---|---|
| Fridge warm, freezer works fine | Evaporator fan motor, defrost system failure, thermistor | Call a pro |
| Both fridge and freezer warm | Dirty condenser coils, compressor failure, start relay | Vacuum coils first; Call a pro if no improvement |
| Fridge running constantly, not cold enough | Dirty condenser coils, worn door gasket, low refrigerant | Vacuum coils, check gasket; Call a pro for refrigerant |
| Not cooling after power outage | Control board needs reset, tripped breaker | Try reset first (see below how) |
| Ice buildup on back wall inside fridge | Defrost system failure it’s heater, thermostat, or timer | Call a pro |
| Ice maker stopped working | Water inlet valve, ice maker arm, temperature sensor | Check arm position first; Call a pro for valve |
| Water dispenser not working | Water inlet valve, frozen water line, control board | Call a pro |
Whirlpool Refrigerator Not Cooling But Freezer Is Fine
This is the most specific symptom and it tells us a lot. If your Whirlpool fridge is not cooling but the freezer is working, the cooling system itself is functioning. The problem is with airflow from the freezer to the refrigerator compartment. The following is what collapses in this pathway:
Evaporator Fan Motor Failure
The evaporator fan motor circulates cold air from the evaporator coils through both the freezer and refrigerator sections. When the fan fails, the freezer will remain cold since it is immediately adjacent to the coils – the fridge part will not get any airflow and will be heated. Sometimes you can even hear it: a working evaporator fan produces a constant hum. When it goes quiet or if it produces a grinding sound, then the problem is probably the fan motor.
Defrost System Failure
Whirlpool refrigerators have an automatic defrost system to avoid the formation of ice on the evaporator coils. A defrost heater, defrost thermostat or defrost timer will fail and the coils will be covered in frost until it fully seals off the airflow. The outcome: a still-functioning freezer in a warm fridge. And, when you notice that there is thick frost on the back wall in the fridge section, this is likely the cause.
Thermistor (Temperature Sensor) Failure
The temperature sensor (thermistor) tells the control board how cold each section is. A defective thermistor will give wrong signals and the board believes that the fridge is already cold enough and will not start the cooling process even when it is not. This is more difficult to diagnose at home since the fridge seems to be running well.
All these three need to open internal panels and test using a multimeter. If your Whirlpool refrigerator is not cooling but the freezer works, call Wilson and Myers- its one of our most frequent same-day refrigerator repair calls in Denver Metro and Boulder.
Whirlpool Refrigerator Not Cooling or Freezing
When both sections are warm and your Whirlpool refrigerator is not cooling or freezing at all. The problem is earlier in the system. Think: power, compressor, or condenser.
Dirty Condenser Coils
This is the #1 cause of a Whirlpool fridge not cooling and the easiest DIY fix. Most Whirlpool models have the condenser coils at the bottom behind a kick plate or at the rear. They are unable to cool down when covered with dust and pet hairs. The compressor must strain more, overheats and eventually the fridge ceases to cool altogether. Pull back the kick plate, clean them with coil brush or vacuum. Give fridge 24 hours to cool down.
Start Relay Failure
The compressor is started with a jolt of power by the start relay. When the start relay goes dead, the compressor will not start at all or it will start and stop every few minutes – you will hear a clicking noise. Toss the start relay (a little part that is inserted on the side of the compressor): when it rattles, it is dead. This is a fairly easy DIY replacement provided that you are not afraid of removing the fridge and getting to the back panel.
Compressor Failure
The Whirlpool refrigerator compressor is the heart of the sealed system it circulates refrigerant through the coils. On older Whirlpool units (10+ years), compressor failure is possible, especially if the condenser coils were chronically dirty. Signs: the compressor runs but the fridge doesn’t cool, or the compressor doesn’t run at all. Compressor replacement involves handling refrigerant, which requires EPA 608 certification this is always a professional job. If the compressor is gone on an older unit, call Wilson & Myers and we’ll give you an honest assessment on whether repair makes sense.
Whirlpool Refrigerator Not Making Ice
Whirlpool refrigerator not making ice is a separate issue from general cooling. The refrigerator could be iced to the core and the ice maker could be idle. The order to check things is as follows:
| 1 | Check the ice maker arm. The shut-off arm (metal) is to be in the down position to make ice. When it gets stuck up, the ice maker believes that the bin is full and will not make ice. |
| 2 | Check freezer temperature. The ice maker requires the freezer to be 0F -18 C or colder to make ice. In case it is hotter, correct the cooling problem. |
| 3 | Check the water supply line. There is a kinked or frozen water line behind the fridge meaning that no water goes to the ice maker. Strauss the line or warm it with a towel. |
| 4 | Water inlet valve. When the line is narrow but does not allow water to pass, the water inlet valve is most probably defective. This valve is opened so a fill cycle could occur when there is an ice maker request. A bad valve is to be replaced, so call a professional. |
The Whirlpool refrigerator water dispenser is fed by the same water inlet valve which supplies the ice maker. In case the ice dispenser and the water dispenser have failed at the same time, then it is likely that the valve is the faulty one.
How to Reset a Whirlpool Refrigerator Not Cooling After Power Outage
When your Whirlpool refrigerator stopped cooling after a power outage, the first step is always to restart it. It lasts 5 minutes and is free.
| 1 | Here is how to reset your Whirlpool refrigerator not cooling. The very first move is just to unplug the refrigerator from the wall outlet |
| 2 | Wait 5 full minutes – this will give time to completely discharge and reset the control board. |
| 3 | Install plug again and adjust temperature to 37F in the fridge and 0F in the freezer. |
| 4 | Allow 24 hours to pass before deciding that it is not working – the fridge will take time to heat up. |
Whirlpool also has a special reset button in the ice maker compartment of certain models. In case the ice maker did not work after a power failure, press and hold it 3 seconds.
Should the fridge not cool down after 24 hours since resetting the fridge – the issue is a mechanical one rather than an electronic one. Don’t keep waiting. Then food spoilage becomes an actual expense. Call Wilson & Myers at (720) 616-2100 for same-day diagnosis.
Whirlpool Refrigerator Not Cooling by Model Type
Whirlpool manufactures a few different refrigerator models and the most frequent points of failure differ a little depending on the model. It is most probable that we will find this at Wilson and Myers:
Whirlpool Side by Side Refrigerator Not Cooling
On the Whirlpool side by side refrigerator not cooling calls, dirty condenser coils are the most frequent offenders – after the evaporator fan and defrost system. The side-by-side design implies that the two parts have the same evaporator system, and a defrost malfunction will impact both sides. Check the damper control between sections also – on certain models may stick open or closed and cause air to not pass through.
Whirlpool French Door Refrigerator Not Cooling
Whirlpool French door refrigerator not cooling is mostly an evaporator fan problem. The fan is located in the freezer section of the refrigerator and when it breaks, it does not allow any cold air to pass to the upper refrigerator. French door models also have more complicated control boards and door-in-door seals that may degrade. Inspect door seals properly and the type of door gasket on a French door will be hard to notice.
Whirlpool Gold Series Refrigerator Not Cooling
Whirlpool Gold refrigerator not cooling and Whirlpool Gold Series refrigerator not cooling are frequent search terms. Gold Series models are very popular and have been in homes long enough to begin to experience age related failures. Our most common issues to diagnose are: defrost system failure, evaporator fan motor, and thermistor failure. The Whirlpool refrigerator control board of the older Gold series is also prone to failure and can be tested prior to spending money on more costly parts.

FAQ
Why is my Whirlpool refrigerator not cooling?
The most common reasons a Whirlpool refrigerator stops cooling are: dirty condenser coils blocking heat release, a failed evaporator fan motor stopping cold air circulation, a defrost system failure causing ice buildup on the coils, or a faulty start relay preventing the compressor from running. Begin by cleaning the condenser coils – it takes 15 minutes and cures more unexpected cases.
My Whirlpool fridge is not cooling but the freezer works. What’s wrong?
This specific symptom points to airflow failure between the freezer and fridge sections. The three most likely causes: evaporator fan motor failure, defrost system blockage (frost on the coils), or a faulty temperature sensor (thermistor) giving incorrect readings to the control board. Each of the three needs to open inner panels – call the professional to get a proper diagnosis.
How to reset whirlpool refrigerator not cooling?
Disconnect the refrigerator, leave it 5 minutes and reconnect it. Allow 24 hours to get it to operating temperature in the fridge and the freezer before deciding that the reset did not work. This is especially worth trying if the fridge stopped cooling after a power outage.
Why is my Whirlpool refrigerator not making ice?
Verify the position of the ice maker arm- it must be down. When there is no ice being generated and the arm is down, make sure that the freezer is 0 F or lower. Assuming the temperature is okay, then the suspect most likely is the water inlet valve. A failed valve also stops the Whirlpool refrigerator water dispenser and if both have stopped at the same time, the valve needs replacement.
Is it worth repairing a Whirlpool refrigerator that is not cooling?
Generally yes, unless the compressor has failed on a unit that’s 12+ years old. Most Whirlpool refrigerator troubleshooting not cooling issues are fan motor, defrost system, thermistor, start relay are cost-effective repairs that extend the life of the appliance significantly. At Wilson & Myers, we always give you a complete diagnosis and honest recommendation before any Whirlpool fridge repair begins.
