A Whirlpool fridge must have all of its components in good working order to cool any items inside. So, if your Whirlpool fridge can’t stay cool, we’re here to help.
A Whirlpool fridge will not be able to cool properly if it has dirty condenser coils. Besides that, failed fan motors on the condenser or the evaporator coils could also prevent the fridge from removing hot air and distributing cold air. Lastly, the
In the following sections, we’ll show you which parts on your Whirlpool fridge to troubleshoot to get your fridge cold again.
What causes a whirlpool refrigerator to stop cooling?
Before performing any repairs on your Whirlpool fridge, be sure to disconnect the power supply to the appliance. You must do this to avoid the risk of electrocution and reduce the risk of injury, especially when working closely with the fridge’s components.
Dirty Condenser Coils
The condenser coils of your Whirlpool fridge are located at the back of the appliance, typically closer to the floor. These coils are part of the fridge’s closed-loop cooling system, which circulates refrigerant.
Once the refrigerant has absorbed all of the heat on the fridge’s inside, it will flow through the condenser coils on the back to release that heat away from the fridge.
The condenser fan helps with this process by ensuring continual airflow past the coils, allowing them to release heat even quicker.
How it fails:
With air continually blowing past the condenser coils, they tend to accumulate plenty of dirt and dust quite quickly. As this buildup gets worse, the coils become a lot less efficient at releasing the heat from the refrigerant that passes through.
That starts a chain reaction that prevents the Whirlpool fridge from cooling. With dirty condenser coils, the refrigerant continues flowing through the closed-loop cooling system at a high temperature, which keeps the fridge warm instead of cooling it down.
How to fix:
Fixing dirty condenser coils is very straightforward. First, move the fridge away from the wall so you can have easy access to its condenser coils at the rear. Next, you will need to remove any panels that might be covering those coils.

As mentioned earlier, the fridge must be turned off before you do this. That’s because the condenser fan is located in the same area and could injure your fingers.
Using a vacuum and a brush, clear all of the dust from the condenser coils. For maximum efficiency, you should clean these coils regularly to prevent future buildups of dust. Doing this once a year would be a good frequency to start with.
Faulty Condenser Fan Motor
As mentioned above, the condenser coils help to cool down the refrigerant that circulates in the fridge’s cooling system. However, the condenser coils can’t do this effectively on their own and need plenty of help from the condenser fan.
This fan continuously blows air past the condenser coils, allowing heat to dissipate into the air behind the fridge. The condenser fan motor must be in good working order and operating at total efficiency for the fan to do this.
How it fails:
If the condenser fan isn’t working, the motor may have shorted out or broken down from excessive wear and tear.

To troubleshoot the motor, first, ensure that nothing is stopping the fan blades from turning. That could happen due to a dust or dirt buildup or foreign objects getting stuck between the blades.
When you’re sure that the fan is free from any obstructions, try to turn the fan blades manually. If you can turn the fan blades, that means there’s nothing stuck in the blades. So, the motor may have shorted out.
How to fix:
To resolve this issue, you’ll need to replace the condenser fan motor. First, remove the access panel covering the condenser section of the fridge, and place it to the side.
Once you’ve reached the condenser fan, remove the fan blades first. Then, unthread the screws holding the condenser fan motor in place and disconnect its power connector.
Mount the new condenser fan motor in the same way as before, and reconnect the power connector. Then, attach the fan blades, and put the access panel back on the fridge.
Faulty Evaporator Fan Motor
Besides the condenser fan in your Whirlpool fridge, there is another fan located at the evaporator as well. When the refrigerant flows through the evaporator section of the cooling system, it’s at a very low temperature. As a result, the evaporator cools down the fridge’s inside by absorbing heat while supplying cold air.
The evaporator will cool down the fridge efficiently as long as the fan is helping to distribute the cool air coming off of it.
How it fails:
If your Whirlpool fridge isn’t reaching the temperature that you’ve set, it could be because the evaporator fan motor has failed. For instance, the motor might have shorted out or burned out. If the fridge has been in use for a long time, it’s also likely that the motor has been through lots of wear and tear and stopped working correctly.

If you have a multimeter, you could test the evaporator fan motor for continuity to be sure. Plus, you could also look out for other symptoms, such as if the motor runs very noisily.
How to fix:
To resolve this issue, you’ll need to take out the existing evaporator fan motor and replace it with a new one. Unlike the condenser, the evaporator fan motor is located inside the fridge. So, you’ll be accessing it from inside the fridge compartment.
First, remove all the contents of the fridge, including its shelves. Then, remove the back panel to expose the evaporator coil. Here, you should be able to locate and identify the evaporator fan motor quickly.
Unthread the screws holding the motor housing in place and disconnect the electrical connector. Once you’ve removed the housing, you can then take off the fan blade before removing the old motor.
Place the new motor on the housing. Then, work your way backwards: reattach the fan blades to the motor shaft, mount the housing in the fridge, and plug the electrical connectors back in. Lastly, replace the panels that you removed earlier.
Broken Temperature Control Thermostat

Suppose your Whirlpool fridge is too warm. If that’s the case, the thermostat will supply power to the cooling system to remove heat and generate cold air.
As soon as the thermostat senses that the fridge has reached your set temperature, it will shut off the cooling system to avoid over-cooling the fridge and wasting energy.

The control thermostat will have electrical connectors and a capillary tube attached to it. First, remove the connectors, then replace the faulty control thermostat with the new one in the housing.
Lastly, reinstall the housing inside the fridge by reconnecting the wire harness and threading the mounting screws.
Malfunctioning Start Relay
The start relay is a component that starts and powers the compressor. For example, when the fridge isn’t cold enough, the start relay will power the compressor, circulating the fridge’s refrigerant throughout the cooling system to make the fridge cold.
How it fails:
When a start relay gets faulty, it will not keep the compressor running for as long as it should. Worse yet, a failed start relay might not even start the compressor at all. Without any refrigerant circulating throughout the closed-loop cooling system, your Whirlpool fridge will fail to cool down and reach your set temperature.
A common symptom of a failed start relay is a clicking sound coming from the back of your fridge, even though the compressor does not start. Besides that, a burning smell is another sign that the relay has shorted out.
How to fix:
A faulty start relay needs to be replaced. You can do this by accessing it through the back of the fridge.
Depending on the model and its design, you might need to remove a rear panel to access the relay. You’ll find that the start relay is attached to a run capacitor, both of which are attached to the compressor motor.
Disconnect the run capacitor and attach it to the new start relay. Then, attach them back onto the compressor motor.
Whirlpool Refrigerator Not Cooling or Freezing
If you have your fridge not cooling at all in both fridge and freezer compartments, the most likely reason for that is a failed compressor start relay or a major issue with the compressor.
Another possible reason is a main control board malfunction. In this case, you will have lights ON in the fridge section, but the control panel will not respond when you press buttons and you can not enter a diagnostic mode of the Whirlpool fridge.
Whirlpool Fridge Not Cooling Enough
If your fridge not cooling enough, one of the reasons for that is dirty condenser coils. Condenser coils need to be clean in order to provide a proper functioning of the fridge sealed system.
Another possible reason is a leak of refrigerant. If there is a lack of refrigerant in the system, the refrigerator can not provide proper cooling on all compartments.
