Kitchenaid Refrigerator Not Cooling? Here's How to Fix It

Refrigerators are the cornerstone of modern kitchens, and when they fail to maintain their cool, it’s not just an inconvenience—it can lead to food waste and safety concerns. Kitchenaid refrigerators, renowned for their quality and durability, are not immune to occasional issues. If you find your Kitchenaid refrigerator not cooling effectively, there are several steps you can take to diagnose and fix the problem before calling in a professional. Let’s explore some troubleshooting tips and DIY solutions to restore your refrigerator’s functionality.

Check the Basics First

Before diving into more complex solutions, ensure the basics are in order:

  • Power Supply: Verify your refrigerator is firmly plugged in and that the outlet is functional.
  • Thermostat Settings: The refrigerator should be set to the manufacturer’s recommended settings. Typically, the ideal temperature for a Kitchenaid fridge is between 35°F and 38°F (1.7°C and 3.3°C).
  • Door Seal: Inspect the door seal (gasket) for any tears or gaps that could let in warm air, forcing the refrigerator to work harder.

Condenser Coils Cleaning

Dirty condenser coils can cause poor cooling performance. They are typically located beneath the refrigerator and can accumulate dust and pet hair over time.

Steps to Clean the Condenser Coils:

  1. Unplug the refrigerator: Always start by disconnecting the power for safety.
  2. Access the coils: Remove the base grille if necessary.
  3. Clean the coils: Use a refrigerator coil brush or a vacuum with a brush attachment to gently remove dust and debris. Be careful not to damage the coils.
  4. Reattach the base grille: Replace any covers or panels you removed.
  5. Plug the refrigerator back in: Give it a few hours to adjust to the proper temperature.

Evaporator Fan Check

If your freezer is cold but the refrigerator is warm, the evaporator fan might be the issue. This fan circulates cold air from the freezer to the refrigerator.

How to Inspect the Evaporator Fan:

  1. Locate the fan: It’s usually found in the freezer compartment.
  2. Check for obstructions: Ensure no ice or debris is blocking the fan blades.
  3. Listen: A faulty fan may emit unusual noises.
  4. Test the fan motor: If the fan blades are not moving, the motor may need replacement.

Defrost System Failure

A failure in the defrost system can lead to ice buildup, which can block air flow.

Troubleshooting the Defrost System:

  1. Defrost heater: This component melts away any frost that accumulates on the evaporator coils. If defective, it may need replacement.
  2. Defrost thermostat: This safety device prevents the defrost heater from overheating. Test it for continuity.
  3. Defrost timer or control board: If these components are faulty, they may not trigger the defrost cycle as needed.

Start Relay and Capacitor

The start relay assists the compressor in starting up. If the refrigerator is not cooling, the start relay could be the culprit.

Testing the Start Relay:

  1. Access the start relay: It is located at the side or bottom of the compressor.
  2. Test for continuity: Use a multimeter to check for continuity between the start and run terminals.
  3. Inspect for damage: Look for signs of burning or damage. Replace if necessary.

Compressor Issues

The compressor is the heart of the refrigerator’s cooling system. If it’s not working properly, the refrigerator won’t cool.

How to Address Compressor Problems:

  1. Noise assessment: Unusual noises coming from the compressor area could indicate a problem.
  2. Professional diagnosis: Compressor issues are complex and usually require a professional technician.


If your Kitchenaid refrigerator is not cooling properly, follow the above steps to troubleshoot potential problems. Regular maintenance, such as cleaning the condenser coils, can prevent many issues. However, if the problem persists or you’re uncomfortable performing these steps, it’s wise to seek professional assistance.

Remember, timely repairs not only save your refrigerator but also ensure food safety and reduce energy costs. Keep cool, and let your Kitchenaid refrigerator keep doing what it does best!
