Whether you're a seasoned DIY enthusiast or a newcomer to appliance troubleshooting, this guide has the information you need to get your refrigerator working efficiently.
KEY TAKEAWAYS

- Professional maintenance from Sears Home Services can help prevent cooling problems and ensure efficient refrigerator operation.
Common causes for a refrigerator not cooling include dirty condenser coils, dirty or damaged door gaskets, blocked internal air vents, improper installation and failed internal components. Finding the cause of a cooling problem is essential to fixing the the first step to fixing the fridge. Some causes are simple to find and easy to correct, while others may require advanced diagnosis and repair by an appliance technician.
If you’re willing, you can eliminate the simple causes of fridge cooling problems yourself. Follow these simple troubleshooting steps first when you face cooling problems in your refrigerator.
Check for Blocked Air Vents
Blocked air vents can prevent cool air from flowing through the inside of your fridge. The owner’s manual typically shows you where these air vents are located. Find the vents inside your refrigerator and freezer and remove any items that are blocking air flow.
Overpacking or cluttering the inside of the refrigerator or freezer compartment can also inhibit proper air flow and cooling. Toss out expired and spoiled foods regularly to prevent clutter. Organize foods in your fridge to help them last longer and promote proper air flow as shown in this video:
Adjust the Temperature Controls
For optimal cooling performance, it's recommended to maintain temperatures between 35 degrees and 39 degrees in the refrigerator compartment. Setting the fridge temperature at 37 degrees is recommended in most owner’s manuals. Freezer temperature should typically be set at 0 degrees.
When your fridge isn’t cooling well, check if the temperature controls are correctly set. Temperature setting changes may occur if the controls are accidentally touched. Children are sometimes tempted to play with fridge controls. If your refrigerator is malfunctioning due to this issue, adjust the controls to the desired temperature settings. Keep in mind that the temperature changes will not be immediate and could take up to 24 hours for complete equalization of cooling in the fridge.
Look for Loose, Damaged or Dirty Door Gaskets
The door gasket seals help trap cold air inside and keep warm out of your fridge. Check to see if your door gaskets have any cracks or tears or are loose. If a gasket is loose, push it back into the channel around the door or replace it if necessary. You’ll also need to replace any cracked or torn door gaskets.
If the door gaskets are intact but dirty, clean them with mild soap and water to remove spills and deposits. Coat the gaskets lightly with petroleum jelly to keep them lasting longer and sealing properly.
Check for Proper Installation
Refer to the installation guide to complete this troubleshooting step. Retrace the installation steps to see whether your fridge is installed in a proper location with plenty of room on the top, sides and back of the cabinet for ventilation. Most refrigerators need at least ½-inch on each side and 1-inch of clearance on the top and back. Adjust or move the fridge if necessary to gain proper ventilation space around the cabinet.
Ambient Temperature and Humidity Can Affect Cooling
If you’re having cooling trouble with a refrigerator located in the garage, keep in mind that most refrigerators are intended for indoor use where ambient temperatures don’t fluctuate drastically. Your installation guide provide ambient temperature limits for the fridge. When your fridge is in an environment outside those temperature limits, it won’t cool properly. Also, high humidity in some garages can cause cooling problems. The high humidity can cause excessive frost in the fridge that inhibits airflow through the evaporator. Consider moving the refrigerator indoors if possible when it isn’t cooling due to harsh environmental conditions in the garage.
Level the Fridge for Proper Operation and Cooling
Follow the directions in your installation guide to properly level the fridge. Most fridges need to have a slight backward tilt so that doors swing shut smoothly and don’t stay cracked open. Adjust the leveling legs if your fridge isn’t leveled properly.
Clean Refrigerator Condenser Coils
If you’ve been neglecting your condenser coils and your fridge isn’t cooling, you’ll want to clean them ASAP. When the coils have a buildup of dust on them, the coils won’t be able to remove the heat from the refrigerant flowing through it properly. Thankfully, fixing this problem is as easy as dusting. Locate your appliance’s condenser coils — they’re typically in the back or on the bottom of the fridge — and use a brush to get rid of dust. They even make a special brush just for this purpose. To help keep your fridge running smoothly, clean the coils a couple of times a year. Here’s a video that shows you how to clean the condenser coils.

Refrigerant is a chemical compound used in HVAC systems and refrigerators to absorb heat from the environment by cycling through states of evaporation and condensation, enabling the cooling process through its cycle of evaporation and condensation.
R-12 refrigerant, also known as Freon-12, is a chlorofluorocarbon (CFC) compound that was once widely used in air conditioning systems, refrigerators, and aerosol propellants before its phase-out due to environmental concerns.
CFC certification refers to the credentialing process that qualifies HVAC technicians to handle chlorofluorocarbons (CFCs) and other refrigerants in a manner that complies with environmental regulations. It is essential for professionals who install, maintain, or repair HVAC systems and refrigeration equipment.
A refrigerator thermostat is a device within a refrigerator that regulates its temperature by turning the cooling system on and off based on the interior temperature compared to the set desired temperature.
