Why is My Refrigerator Not Cooling?

How To Fix a Refrigerator When It Won't Get Cold!

As someone who has dealt with their Refrigerator Not cooling, I understand the frustration of finding and fixing refrigerator problems. The Fridge is one of the essential appliances in any home, and when it’s not working right, it can create chaos in your household.

With today’s prices, a warm fridge can also be very costly – leading to spoiled food or drinks, so what are the causes for a refrigerator that doesn’t cool?

Today, we will show you the most common refrigerator cooling problems and the best DIY methods to diagnose and repair any refrigerator by yourself.

7 Common Reasons Refrigerator is Not Cooling:

  1. The Refrigerator isn’t plugged in. Seriously, many people pull the fridge out to either clean behind it or recover something that fell behind. It’s easy to jiggle the power cord loose or disconnect it entirely when this happens.
  2. The Condenser Coils are Dirty – located on the back of the refrigerator or in a bottom compartment; the condenser coils can become full of dust or debris, preventing them from functioning correctly and cooling off the fridge.
  3. Freezer Vents are Blocked – Cold air cannot be adequately distributed if bags or boxes of frozen food are piled up, blocking the evaporator fan and freezer vent.
  4. Poor Ventilation – The outside air around the refrigerator is blocked.  This can occur from cabinetry, side obstructions, or the blocked front vent (floor), which prevents air from flowing over the condenser coils.
  5. The Evaporator Fan Motor isn’t working. An evaporator fan motor is in the freezer compartment behind the rear (removable) panel. The evaporator motor and its fan blade distribute cold air throughout the freezer, which also cools the fridge. See How to Replace the Evaporator Fan Motor below.
  6. The condenser fan motor isn’t working – the condenser is located in the bottom compartment of every refrigerator.  The condenser’s job is to compress refrigerant gas into the liquid coolant and pump it to the evaporator coils (In the freezer). 
  7. A typical problem with the condenser is that it is overheating due to a defective condenser fan motor.  See How to Replace the Condenser Fan Motor below.

Troubleshooting refrigerator problems is not always easy, but understanding the dynamics of your freezer and fridge is a great place to start, and doing repairs yourself will save you considerable money.


Diagnosing Refrigerator Problems:

  • Why is my freezer working, but the fridge won’t cool?  One of the most common problems with refrigerators is when the Freezer is freezing, but the fridge is not cold. Another common issue is when the Refrigerator is Cold, but the freezer isn’t freezing.
  • In either case, if the condenser motor (bottom of fridge) is running and the refrigerator isn’t cold, the most likely issue will be an over-iced evaporator coil or a failed evaporator fan. (See fixes below)
  • Suppose the evaporator coil and evaporator fan look good. In that case, the cooling problem could be caused by various issues, including a faulty compressor, a clogged condenser coil, or a malfunctioning thermostat.
  • In addition, dust and debris will also accumulate on the coils, reducing their ability to dissipate heat. This can cause the compressor to work harder and longer, leading to a warmer freezer and a colder fridge.
  • Another possible cause could be a faulty compressor. The compressor is responsible for pumping refrigerant through the coils, and if it’s not working correctly, your freezer will not be able to produce cold air.

    How To Fix a Refrigerator That Isn’t Cooling

    There are several potential reasons why a refrigerator fails to keep your food and drinks cold. These are things to check if your refrigerator won’t cool.

    Refrigerator Cooling Troubleshooting:

    1. First, make sure the refrigerator is powered all the way. The power cord can easily be pulled loose when cleaning behind a fridge.
    2. If your fridge is plugged in – the light inside should turn On when you open the door (unless the bulb is burned out). If the bulb is burned out – replace it, giving yourself a spot-check that your refrigerator is powered on every time you open the door.
    3. Vacuum and Remove any debris or dirt from the refrigerator coils. The coils (depending on the model) are located either behind or underneath the fridge. Dirty or dusty coils on your fridge will indeed impede it from cooling.
    4. The vents in the freezer or boxes of frozen food or spare bags of ice do not block the vents in the freezer compartment. The air in your freezer flows freely to maintain a cold temperature.
    5. Be sure your thermostat has not been adjusted to a shallow setting by mistake. If the thermostat is malfunctioning, you can find simple-to-install replacement thermostats online .
    6. It’s rare, but make sure that nothing is stuck in the condenser fan and that it rotates smoothly. Note: a refrigerator with coils in the back doesn’t have a fan.  Unplug the fridge and pull it away from the wall by spinning the fan blade to check if the fan works correctly.  Next, clean the fan blades and rotate the fan to make sure it turns freely.

    If the blade spins freely, but the fan motor isn’t working, See the DIY instructions: “How to replace Evaporator fan on Fridge” later in this article.

Knowing How a Freezer and Fridge Works

First, It’s important to understand How a refrigerator works. Whether an upright or side-by-side refrigerator, the freezer and fridge work together to maintain a consistent temperature. They operate much like a typical air conditioner.

Essentially, the compressor pushes refrigerant (gas) into the condenser coils.  It then converts to a “liquid,” delivered to the evaporator coils (in the freezer).

The heat is absorbed by the evaporator coils, which cools both the freezer and the refrigerator, keeping your food fresh.

Importance of the Compressor

The compressor, the heart of the refrigerator, pumps refrigerant through the coils in the freezer. As the refrigerant passes through the waves, it absorbs heat and cools the air. The cold air is sent into the fridge to keep your food fresh.

Note:  Condenser coils (shown on the back of the fridge above) are often located inside the bottom compartments of modern refrigerators.


How To Replace Refrigerator “Evaporator Fan Motor”

One of the most likely problems with fridges not cooling correctly stems from a broken evaporator fan or fan motor.

If you have a stuck fan blade or lousy evaporator fan motor, the cold air cannot be circulated and distributed adequately to the freezer and fridge.

The evaporator fan is responsible for circulating air throughout the fridge and freezer; if it’s not working, your food will not get the cold air it needs.

Some (usually older) refrigerators with condenser coils on the back of the fridge (see image below) do not use an “evaporator fan.”

If this is the case with your fridge, See “How to diagnose and replace Condenser Fan motor” later in this article.

Assuming the refrigerator does not have coils on the back of the fridge

  1. Open the freezer, and locate the evaporator Cover on the inside back wall.

2. The fan motor and blade should be spinning With the refrigerator plugged in and the condenser motor running. If the fan motor is running, but the blade isn’t spinning, carefully try to free it.

3. If the fan motor isn’t running or the fan blade is spinning, Unplug the fridge, then Remove the Fan Motor by removing the screws and detaching the fan motor wires.

Note: I always snap a photo of the wiring connections to refer to when installing a new motor.

How To Replace a Refrigerator “Condenser Fan Motor”

The Condenser fan motor on a Refrigerator can be found at the refrigerator’s back side and the bottom by removing the panel (be sure to have the fridge unplugged before removing this panel)

The condenser fan blows cool air over the compressor and condenser coils to keep them from overheating. If the fan motor fails, the condenser and the compressor will not run properly, which keeps the fridge from cooling correctly. 

Follow these Steps: To Diagnose or Replace the “Condenser Fan Motor”

  1. Pull the refrigerator away from the wall and unplug it.

2. Look for and remove the thin cover at the bottom of the fridge, exposing the condenser motor.

3. Keeping hands free from the exposed condenser and plug in the refrigerator to see if the condenser is running and the fan and fan motor are working. If the condenser motor is on but the fan isn’t – you most likely need a new condenser fan motor.

4. If your fridge condenser fan and condenser motor are both not running (try this troubleshooting tip):

  • Unplug the refrigerator
  • Set up a box fan, pointing it directly at the condenser and coils for 20-30 minutes to cool them off.
  • Once the condenser is cool, plug the fridge in again and see if the condenser comes on.
  • If it does, the fan motor is probably the culprit and needs to be replaced. It can also be found online.

  • After replacing the condenser fan, the condenser fails to come on; the condenser itself or the relay is bad. 
  • If this is the case, the repair will be more complex, and you may consider hiring an appliance repair contractor for help.

Why is the Refrigerator warm?

If you find that your refrigerator is warm, a few different things could be causing the issue. One possible cause could be a dirty condenser coil.

As mentioned, dust and debris can accumulate on the coils, reducing their ability to dissipate heat. This can cause your refrigerator to work harder and longer, increasing temperatures.

Another possible cause could be a malfunctioning thermostat. The thermostat is responsible for regulating the temperature in your refrigerator; if it’s not working correctly, your fridge may not maintain a consistent temperature.

Finally, another possible cause could be a refrigerant leak. If there’s a leak in the refrigerant system, your fridge may be unable to cool properly. This is a more severe issue that a professional appliance repair service should address.
