How to Fix Kenmore Refrigerator Not Cooling?
Discussed below are 11 reasons why a Kenmore refrigerator won’t cool, plus how you can fix the unit:
1. Condenser Coils Could Be Filthy/Dirty
Heat dissipation is essential for a refrigerator to cool your food and drink. One component that’s critical in dissipating heat in a Kenmore fridge is the condenser coil.
Sadly, the condenser coils become dirty and dusty over time, and when they do, they cannot dissipate heat.
Fix
Inspect your unit’s condenser coils and clean them if dirty/dusty. You can use a flexible refrigerator coil cleaning brush.

2. The Fridge Could Be Overstuffed with Food
Putting too much food in the fridge blocks the air vents and prevents the cool air from circulating correctly. So, the refrigerator won’t be able to cool properly.
Fix
Examine your food load and reduce the amount if the fridge unit is overfilled. Also, avoid stacking containers close to one another to improve cold air circulation.
3. The Evaporator Fan Motor Could Be Frosted Over
The evaporator fan is essential in drawing air over and throughout the evaporator coils. The coil, in turn, helps to cool your refrigerator and freezer. But over time, the evaporator fan motor becomes iced, unable to dissipate cool air over the coils.
Fix
Test the evaporator fan motor by turning it by hand. If it doesn’t, and it looks icy, test it with a multimeter tester and if it shows no continuity, replace it. But if it does, blow dry it to get rid of ice and adjust the fridge temperature.
4. The Fridge Door Might Be Leaking Air
If you don’t close the fridge door all the way, it’ll allow warm air in, and cold air will leak out, preventing the fridge from cooling. Likewise, if the door gasket/seal is loose or worn out, the door won’t shut properly and will therefore leak.
Fix
Close the fridge door correctly and replace the door gasket if it’s old or loose.
5. The Condenser Fan Motor Might Be Obstructed or Faulty
The condenser fan motor helps to draw in air and circulate it around the fridge. So, fundamentally, it helps to keep your refrigerator cool.
It can, however, become obstructed by ice or dirty or fail. And if that’s the case, it won’t cool the fridge.
Fix
Inspect the condenser fan motor for possible dirt or ice obstruction and clear the block if present. If there’s no obstruction, use a multimeter to test the fan motor for continuity. If it fails the test, replace it.
6. The Temperature Control Thermostat Could Be Malfunctioning
The temperature control thermostat is pivotal in supplying the fan motors and the unit’s compressor with the necessary voltage to run.
For cooling to occur, the compressor and the two fan motors (evaporator and condenser fan motor) must work. So, their failure means no cooling.

Fix
Test the temperature control thermostat with a multimeter and replace it if it shows no continuity.
7. The Start Capacitor Might Be Defective
The start relay has to be functional for the compressor to run. If it’s faulty, the compressor will fail, and the fridge won’t cool the food supplies.
Fix
Use a multimeter to examine the start relay for fault. If the start relay doesn’t show continuity, consider replacing it. It’s likely to be faulty.
8. The Thermistor Could Be Faulty
The job of the thermistor is to monitor the Kenmore fridge temperature and relay the information to the main control board. The control board, in turn, enables the evaporator fan motor and the compressor to run and cool the unit.
So, if the thermistor is faulty, all that won’t occur, and there won’t be any cooling.
Fix
Using a multimeter, test the thermistor’s continuity. If it shows no continuity, replace it.
9. The Compressor Might Be faulty
The compressor compresses the unit’s refrigerant and redistributes it across the coils. The condenser and evaporator coils won’t cool the fridge unit if it fails.
However, it’s worth noting that the compressor doesn’t fail often. So, it should be one of the last things to check. (www.harveymaria.com)
Fix
Use a multimeter to test the pin terminals on the compressor. If the pins don’t show continuity, the compressor is faulty. So consider replacing it.
10. The Temperature Control Board Could Be malfunctioning
The temperature control board, like the temperature control thermostat, passes the necessary voltage to the fan motors and compressor.
If it’s faulty, the control board will misdiagnose the voltage information, causing the fan motors and compressor to fail.

Fix
Have an expert examine the temperature control board for faults and replace it if it’s malfunctioning.
11. The Main Control Board Might Have Failed
Lastly, your last resort is the main control if the problem is none of the above 10. The problem with a faulty main control board is that it fails the cooling unit and the Kenmore refrigerator ice maker, dispenser, and other parts.
Fix
If other parts plus the cooling unit are not working, the main control board could be faulty and need a replacement.
My Kenmore Refrigerator Not Cooling But Freezer Is Fine
Sometimes, a Kenmore refrigerator won’t cool while its freezer is fine. That often happens due to these reasons:
- Faulty evaporator fan motor – A defective evaporator fan motor could cause the fridge to fail without affecting the freezer. So, test it with a multimeter and then replace it if it’s faulty.
- Fridge overload – If it’s only the fridge overloaded with food and not the freezer, the freezer will work fine while the refrigerator won’t cool. In such a case, reduce the food to create more room for cold air circulation.
- Excessive Frosting – If the refrigerator compartment is as cold as the freezer, frost will form over the evaporator coils, making them unable to cool the fridge. If so, you need to adjust the fridge temperature and allow the unit to dethaw by unplugging it.
- Defective defrost component – If the defrost timer, thermostat, or control board is bad, the fridge won’t cool until you replace the faulty part.
- Stuck damper control – If the damper control is stuck, it won’t be able to allow cool air to stay in the refrigerator, and so the fridge won’t cool. You’ll need to unstick it if that’s the case.
- Door leak – Ensure you close the fridge door properly and replace the door seal if it’s loose or broken. It could be the reason the unit won’t cool.
Kenmore Refrigerator Not Cooling After Power Failure
If your Kenmore refrigerator is not cooling after a power failure, it’s more likely that the circuit breaker has tripped. So, you need to look at it and fix it.
After that, consider resetting the fridge using these steps:
- Identify the ultra-ice and home switches inside your fridge door and press them at the same time
- Hold the pair of buttons for about 5 seconds until the controls go off
- Unplug the refrigerator for about 2 minutes, and then plug it in
Kenmore Elite Refrigerator Not Cooling Error Code
If your Kenmore Elite refrigerator won’t cool and show the error code immediately after a power failure, the chances are that something got burnt.
So, you may need to inspect the temperature control thermostat, the fans, and the compressor as they are the most susceptible to an electrical fault. If any is faulty, replace it.
