1. Check the Thermostat Settings

When troubleshooting a Whirlpool refrigerator not cooling, start by checking the thermostat settings. Ensure it’s set between 35-40°F (1-4°C) for optimal performance. Use an external thermometer to verify accuracy.

  • Examine control panel or temperature dial.
  • Adjust settings cautiously if necessary.
  • Some models have advanced electronic displays; others have basic temperature dials.
  • Utilize an external thermometer for accurate assessment.

Regularly inspect and fine-tune thermostat settings to maintain efficient cooling.

2. Inspect the Condenser Coils

Inspecting and cleaning the condenser coils is crucial for addressing cooling issues in a Whirlpool refrigerator. Over time, these coils gather dust and debris, hindering heat release and causing refrigeration problems.

  • Regularly inspect and clean condenser coils to prevent cooling issues.
  • Disconnect power supply before inspection.
  • Locate coils at the back or bottom of the refrigerator.
  • Visually inspect for dirt buildup.
  • Use a soft-bristle brush or vacuum to remove debris.
  • Check surrounding parts for damage or disconnected wires.

Regular maintenance ensures optimal performance and helps prevent potential temperature problems in your refrigerator. By keeping condenser coils clean and unobstructed, you can troubleshoot issues before they escalate, saving time and avoiding costly repairs.

3. Examine the Evaporator Fan

When dealing with a Whirlpool refrigerator not cooling, the evaporator fan is a critical component to check. It maintains airflow, ensuring proper circulation of cold air throughout the unit. Here’s how to examine and troubleshoot it:

  • Start by disconnecting the refrigerator from power for safety.
  • Access the evaporator fan usually located inside the freezer compartment.
  • Remove any obstructions like ice buildup or debris.
  • Manually rotate the fan blades to check for smooth movement.
  • Difficulty rotating or stiffness may indicate motor or bearing issues.

Contact professional repair help if problems persist to avoid further complications. Examining the evaporator fan is crucial for diagnosing cooling problems in your Whirlpool refrigerator, providing insights into potential issues and ensuring effective resolution.

4. Assess the Condenser Fan

Troubleshooting a Whirlpool refrigerator’s cooling issue often starts with assessing the condenser fan. This fan is crucial for maintaining airflow and heat dissipation within the system.

  • Visual Inspection: Unplug the refrigerator and locate the condenser fan near the compressor. Check for visible damage or blockages like dust or pet hair.
  • Cleaning: Gently clean any debris using a soft brush or compressed air, ensuring smooth rotation of the fan blades.
  • Manual Testing: Carefully spin the condenser fan by hand to check for smooth rotation without resistance, indicating a functioning motor.
  • Listen for Noise: Pay attention to any unusual noises during operation, which could signal issues like worn-out bearings or loose mounting brackets.

5. Verify the Refrigerator Door Seal

A vital aspect of preserving optimal cooling performance in a Whirlpool refrigerator is ensuring the integrity of the door seal. Also known as a gasket, this component forms an airtight barrier between the fridge compartment and the external environment.

  • Visually inspect the door seal for cracks, tears, or deformations along its edges.
  • Run your hand along the entire length of the gasket to detect any irregularities or gaps.

To assess the seal’s effectiveness:

  • Perform a dollar bill test by closing a bill or piece of paper in the door and gently attempting to pull it out.
  • If there’s resistance and slight tension, the seal is effective. If it easily slides out or light passes through in a darkened room, there may be air leakage due to a faulty gasket.

6. Clear Blocked Air Vents

Air vents blockage is a common issue leading to improper cooling in Whirlpool refrigerators. When vents are blocked, cold air circulation is restricted, causing inadequate cooling throughout.

Identifying and Resolving the Issue

  • Locate air vents in the freezer compartment and at the back of the fridge section.
  • Inspect for obstructions like food, ice buildup, or debris.
  • Use a soft brush or vacuum cleaner with a brush attachment to clear vent openings.
  • Gently remove dust or debris from both sides of the vent openings.
  • For ice buildup, defrost the refrigerator by turning it off and letting it thaw for several hours.
  • Wipe away excess water and ensure compartments are dry before turning the appliance back on.

7. Troubleshoot the Defrost System

When troubleshooting a Whirlpool refrigerator that isn’t cooling properly, it’s crucial to examine the defrost system, which can accumulate ice on the evaporator coils, hindering cooling. Here are steps to troubleshoot and fix the issue:

  • Defrost Timer or Control Board: Malfunctioning components like the defrost timer or control board may fail to initiate the defrost cycle, leading to ice buildup. Use a multimeter to test their functionality following the refrigerator’s manual. Replace defective parts accordingly.
  • Heater Element: Inspect the heater element, which melts ice during the defrost cycle. Look for physical damage or burn marks. If damaged, replace it as per Whirlpool’s guidelines.
  • Bi-metal Thermostat or Defrost Sensor: Check the bi-metal thermostat and defrost sensor for temperature monitoring in the freezer. Test them for continuity using a multimeter. Replace any faulty or damaged components promptly.

By troubleshooting the defrost system, you can address cooling problems in your Whirlpool refrigerator. Follow the appliance manual and Whirlpool’s guidelines for proper repair procedures. If uncomfortable with electrical components, seek assistance from a qualified technician.


By following the 7 steps outlined in this article, you can identify common issues such as thermostat misadjustment, condenser coil blockage, evaporator fan malfunction, condenser fan failure, faulty door seal, blocked air vents, or problems with the defrost system. These steps provide a comprehensive guide for DIY fridge repair and can save you time and money.

By implementing these refrigerator cooling tips and regularly checking for any signs of malfunctioning components or issues mentioned in this article’s subtopics, you can extend the lifespan of your appliance while enjoying uninterrupted refrigeration. 

Take control of your appliance’s performance by following these steps carefully. With a little effort and attention to detail, you can restore optimal cooling functionality to your beloved Whirlpool refrigerator
