Whirlpool refrigerator can be a great choice for smart people. It runs smoothly years after years with the least maintenances. Generally, a user faces the least issues from it. Among different types of minor issues, Whirlpool refrigerator not cooling or freezing is one of them.
It doesn’t take much time for a technician to back your refrigerator on the track. However, you must spend time and money for that. But when you know the reasons behind this problem, you can fix your refrigerator at home most of the time.
Here I am going to discuss the most common reasons behind this cooling issue and their best solutions. Just stay with me till the end.

How to Fix a Not Cooling or Freezing Whirlpool Refrigerator
Fix your Whirlpool refrigerator’s cooling issue by setting temperature properly or removing some loads. Cleaning clogged condenser coil or replacing defective, condenser fan motor, start relay, start capacitor, temperature control thermostat, thermistor, compressor or main control board can also fix this problem.
Technician recommends the following solutions. You should apply them one by one. If you don’t find solution in one step, go to the next.
Set Temperature Correctly
If your Whirlpool refrigerator shows freezing issue, check the temperature whether it is set correctly or not. Sometimes, misconfiguration of this setting results in a cooling issue. So, it is your first duty to check the manual and set the recommended temperature setting to stop cooling issue.
Remove Some Loads
Every fridge has its own capacity. If your device is showing cooling problem, check the inside for overload. If it is overloaded, reduce some loads to the manufacturer’s recommended level. Hope, it will solve the problem.
Clean Condenser Coil to Avoid Cooling Issue
Refrigerator passes heat outside of the device through it. Due to time growing and not cleaning, dirt can take place into the condenser coil and clog it. As a result, condenser coil fails to pass heat outside of the device and dissipates heat into the machine. In this situation, your refrigerator’s cooling unit may work but it will be neutralized. Therefore, you will notice a cooling or freezing issue in your unit.
Now apply this easy solution-
- Locate the condenser coil. Usually, it is in the backside of your refrigerator.
- Remove this part from the device.
- Clean the dirt from the inside of this coil with a brush. (Note: There are different types of brushes. Use them as necessary.)
- Now vacuum for the remaining dirt.
Condenser Fan Motor
In most of the Whirlpool refrigerator’s model, it is located between the compressor and the condenser coils. This part is responsible for flowing air through the coils and over the compressors. If the condenser fan motor is damaged physically or electrically, your Whirlpool refrigerator will fail to cool its inside. So, you must check it-
- Firstly, check motor’s fan for any obstructions and remove them if you find.
- Secondly, turn the motor clockwise and anticlockwise. If it doesn’t spin freely, change it.
- Thirdly, if the condenser fan motor spins freely, test it with a multimeter for continuity. If there is no continuity, you must replace it to solve cooling issue.
Evaporator Fan Motor
This part is used to circulate cool air to the refrigerator and the freezer compartments. The latest models of Whirlpool refrigerator comes with more than one evaporator fan motor. If it is defective, the freezer compartment or the whole refrigerator won’t be cool. So, fix it-
- Spin the fan blade clockwise and anticlockwise by hands. If it fails to spin freely, replace the motor.
- Does the motor spin freely but fails to run? Take a multimeter and check the motor windings for continuity.
- If multimeter doesn’t show the expected reading, the fan motor is defective. So, you must replace it with a new one.
Start relay works with the start winding combinedly to start the compressor. Due to a defective start relay, your fridge fails to start the compressor. As a result, your device won’t be cool enough or won’t cool at all.
- Take a multimeter. Test start relay between the run and start terminal socket.
- If multimeter doesn’t show continuity, replace it with a new one.
- Besides, if the start relay smells a burnt odor, replace it to solve your whirlpool fridge cooling problem.
Temperature Control Thermostat
Using the temperature control thermostat, your refrigerator passes voltage to the compressor, evaporator fan motor and condenser fan motor. If this part becomes defective, whole refrigerant system will break down. So, you must confirm about it.
- Rotate this thermostat from lowest to the highest.
- If the thermostat is working, you may notice a click sound. Otherwise, it is problematic.
- Run a multimeter test to the thermostat for continuity. If you don’t get any continuity, replace it.
When you start your refrigerator, its compressor needs a boost to start. This boost is provided by the start capacitor. If the start capacitor is defective, you can’t expect a cool fridge.
- Test the start capacitor with a multimeter for continuity.
- If it fails to show continuity, you must replace it to back your refrigerator’s freezing system.
Temperature Control Board
Actually, this temperature control board dominates the cooling system of your refrigerator. Depending on your temperature setting, it provides the required voltage to the compressor and the fan motors. A damaged control board fails to provide voltage to the cooling system. But it is one of the least problematic parts of the refrigerator.
So, you should check all other commonly defective parts before checking or replacing it. As it is costly, you should ask a technician to check what is preventing your unit from cooling before replacing temperature control board.
Thermistor continuously takes the reading of temperature of your refrigerator and sends it to the control board. Control board provides voltage to the compressor and evaporator fan accordingly. Control board fails to get reading from a faulty thermistor. As a result, it cannot send voltage to the necessary components. Therefore, your machine won’t be cool. So, identify whether thermistor is defective or not.
- Check thermistor’s resistance with a multimeter.
- Resistance should change with the change of temperature of your refrigerator.
- If there is no change in thermistor’s resistance or there is no continuity, you must replace it.
Compressor is like a pump. It compresses the refrigerant and sends it through evaporator and condenser coils. If compressor fails to do its job, your refrigerator’s freezing system will be stopped. But compressor is a rarely defective part. Before, replacing it, you must check all other commonly problematic parts.
Replacing a processor is a complex process and needs experienced hands. So, if you have already checked the most common parts but the cooling system is still in problem, ask a professional technician to replace the compressor.
Main Control Board
Due to a problematic main control board, your refrigerator’s cooling or freezing system will stop. But it doesn’t happen in maximum cases. Because manufacturer design and produce this part with great care.
Besides, it is the most durable part of your device. If you have already checked all the steps above but the problem has not been fixed yet, the problem is with the main control board. So, you can consider it to replace.
All of the above mentioned solutions are practical and recommended by the manufacturer. So, you can consider them while fixing your whirlpool refrigerator not cooling or freezing problem. Firstly, try the most common solution and then the rest.
If you aren’t used to repairing home appliances then I suggest you not to try the complex solutions that need opening and removing many parts. Rather, send it to an expert near you.
