1. Dirty condenser coils

The condenser coils on your Whirlpool refrigerator are responsible for dissipating heat from the refrigerant. Over time, these coils can become dirty and clogged with dust, dirt, and other debris. This can reduce their ability to dissipate heat, causing the refrigerator to work harder to cool down. As a result, your refrigerator may not be able to maintain the proper temperature, leading to food spoilage and wasted energy. To clean your condenser coils:

  • Unplug the refrigerator from the power outlet.
  • Remove any food or items from the fridge.
  • Locate the condenser coils on the back or bottom of the fridge.
  • Use a vacuum cleaner with a long nozzle attachment to clean any dust and debris from the coils.
  • Wipe down the coils with a damp cloth to remove any remaining dirt.
  • Allow the coils to dry completely before plugging the fridge back in and returning any food items.

2. Faulty condenser fan motor

A refrigerator condenser fan motor circulates air through the condenser coils to keep them cool. If the condenser fan motor is defective, the fridge will not be able to properly cool food. To test the condenser fan motor, make sure that it is getting power by checking the continuity of the wires leading to it. If the wires are all intact, then use a multimeter to test for continuity in the winding of the motor itself. If there is no continuity, then the motor will need to be replaced.

3. Malfunctioning evaporator fan motor

This component is responsible for circulating air inside the fridge, and if it’s not working properly, the air can become stagnant and warm. There are a few signs that you can look for to see if your evaporator fan motor is having issues. If you notice that your fridge is warmer than usual, or that there is excessive condensation on the walls or shelves, these could be indications that the fan motor is not functioning correctly.

If you suspect that your evaporator fan motor is to blame for your Whirlpool refrigerator not cooling properly, there are a few things you can do to try and fix the problem. First, check to make sure that the fan blade is free of any debris or obstructions. If there is something blocking the blade, simply remove it and see if that solves the issue.

Another potential fix is to lubricate the bearings in the fan motor. This can help keep it running smoothly and prevent it from seizing up. Finally, if neither of these solutions works, you may need to replace the evaporator fan motor entirely.

4. Defective start relay

1. Defective start relay – A defective start relay can prevent the compressor from starting. If the start relay is defective, the compressor may not start even when the refrigerator is turned on. To test the start relay, use a multimeter to test it for continuity. If the start relay does not have continuity, replace it.

The start relay is an electrical component that helps start the compressor in a refrigerator. If the start relay is not working correctly, the compressor may not start, and the refrigerator will not cool adequately. You may notice a clicking sound coming from the back of the refrigerator or that the compressor is not running at all. To fix the problem, you need to replace the defective start relay with a new one. Before replacing the relay, remember to unplug the refrigerator and discharge any capacitors to avoid electric shock.

5. Low refrigerant level

If your Whirlpool refrigerator is not cooling, one of the first things you should check is the refrigerant level. The refrigerant is what helps keep your food and drinks cold, so if it’s low, that could be why your fridge isn’t working properly.

There are a few ways to check the refrigerant level. One is to look at the sight glass on the side of the fridge. If it’s low, you’ll see a bubble or two in the glass. Another way to check is to listen for a hissing sound coming from the fridge. This means there’s a leak in the system and you’ll need to have it repaired by a professional.

Once you’ve confirmed that the refrigerant level is low, you’ll need to add more. You can do this yourself by purchasing a can of refrigerant from a hardware store and following the instructions on the label. Or, you can call a professional to do it for you. Either way, adding more refrigerant should fix the problem and get your fridge back to working properly.

6. Faulty temperature control thermostat

The temperature control thermostat regulates the temperature inside the refrigerator. If the thermostat is not working correctly, it may not be able to sense the temperature correctly, resulting in cooling issues. Signs of a faulty thermostat include the refrigerator not cooling at all or the temperature inside the fridge being too high or too low. To fix the problem, you may need to replace the faulty thermostat with a new one. Before replacing the thermostat, make sure you unplug the refrigerator and remove any covers to access the thermostat.

7. Damaged door gasket

The door gasket is the rubber seal that lines the edges of the refrigerator door. It helps maintain a proper seal, keeping cool air inside the fridge. If the door gasket is damaged or worn out, it can cause air leaks, resulting in cooling problems. You may notice frost buildup inside the fridge or condensation on the outside of the fridge. To fix the problem, you may need to replace the damaged door gasket with a new one. Before replacing the gasket, remember to unplug the refrigerator and remove the old one carefully to avoid damaging the fridge.

8. Broken and faulty motherboard

The motherboard or control board manages various functions of the refrigerator, including the cooling system. If the motherboard is broken or faulty, it may cause the refrigerator to stop cooling correctly. Signs of a broken or faulty motherboard include the refrigerator not turning on or not cooling at all. To fix the problem, you may need to replace the broken or faulty motherboard with a new one. Before replacing the motherboard, make sure you unplug the refrigerator and discharge any capacitors to avoid electric shock. Additionally, ensure that the new motherboard is compatible with your specific refrigerator model.


If your Whirlpool refrigerator is not cooling, the first thing you should do is check the temperature settings. Make sure that the fridge is set to a temperature that is cold enough for your needs. If the problem persists, check to see if the fridge is properly ventilated. If there is no airflow around the fridge, it will not be able to cool properly. Finally, if the condenser coils are dirty, they will need to be cleaned in order for the fridge to function correctly.
