Understanding the Basics: How Your Whirlpool Refrigerator Cools

Before diving into troubleshooting, let’s briefly touch upon how a refrigerator cools. Your Whirlpool fridge uses a refrigeration cycle that involves a few key components:

• Compressor: This is the heart of the system. It compresses refrigerant gas, increasing its temperature and pressure.
• Condenser Coils: Located at the back or bottom of the refrigerator, these coils release heat from the hot refrigerant gas, causing it to turn into a liquid.
• Evaporator Coils: These coils, usually found inside the freezer compartment, absorb heat from the air inside the refrigerator. The refrigerant turns back into a gas, cooling the air in the process.
• Refrigerant: A special substance that circulates through the system, absorbing and releasing heat.
• Thermostat: This controls the compressor, turning it on and off to maintain the desired temperature.
• Fans: The condenser fan cools the condenser coils, while the evaporator fan circulates cold air within the fridge and freezer compartments.

A problem with any of these components can lead to your Whirlpool refrigerator not cooling correctly.

Troubleshooting Steps: Whirlpool Refrigerator Not Cooling

Now, let’s get into the troubleshooting process. We’ll start with the easiest fixes and then move on to more involved checks.

1. Initial Checks: The Simple Things First

• Check the Power Supply: Is the refrigerator plugged in correctly? Make sure the power cord is securely connected to the outlet. Try plugging a different appliance into the same outlet to verify if the outlet is working. If the outlet is faulty, you’ve identified the issue!
• Check the Circuit Breaker: Go to your circuit breaker panel and ensure the breaker for the refrigerator hasn’t tripped. If it has, switch it off, wait a few seconds, and switch it back on. If it trips again immediately, there may be a short in the refrigerator and you should consult a technician.
• Verify the Temperature Settings: Ensure the temperature controls are set correctly. If the settings are too warm, the fridge won’t cool properly. Refer to your Whirlpool refrigerator’s user manual to find the recommended settings for both the refrigerator and freezer. Typically, the refrigerator compartment should be between 35-40°F (2-4°C), and the freezer compartment should be at or below 0°F (-18°C).
• Door Seals Inspection: Carefully check the refrigerator and freezer door seals for any tears, damage, or areas where they are not making proper contact with the refrigerator frame. A faulty door seal will allow warm air to enter, making it difficult for the fridge to maintain a cool temperature. You can test the seal by closing the door on a piece of paper. If you can easily pull the paper out with the door closed, the seal is likely not doing its job.
• Airflow Obstruction: Ensure there are no items blocking the vents inside the refrigerator or freezer. Proper air circulation is crucial for efficient cooling. Avoid overpacking the refrigerator and make sure nothing is touching the vents.
• Recent Loading: If you have just loaded the fridge with a lot of warm or room-temperature items, it might be temporarily struggling to cool down. Give it 12-24 hours to stabilize.

2. Checking the Condenser Coils

The condenser coils release heat from the refrigerant. If they are covered in dust or debris, the refrigerator’s cooling performance will be significantly impacted.

1. Locate the Condenser Coils: These are typically found at the back of the refrigerator or on the bottom near the floor. You’ll usually see a set of tubes or coils.
2. Unplug the Refrigerator: Always unplug the refrigerator from the power outlet before cleaning the coils. This is crucial for your safety.
3. Clean the Coils: Use a vacuum cleaner with a brush attachment to remove dust, pet hair, and other debris from the coils. If the dirt is caked on, you can use a soft brush to loosen it and then vacuum. For stubborn dirt, a damp cloth may be used after vacuuming, ensure that the area is completely dry before restoring power.
4. Restore Power: Plug the refrigerator back into the outlet and give it time to cool down. Check if there’s an improvement in cooling.

3. Examining the Evaporator Fan Motor

The evaporator fan circulates cold air throughout the refrigerator. If it malfunctions, the fridge won’t cool effectively. Here’s how to check it:

1. Locate the Evaporator Fan: This fan is usually located inside the freezer compartment, behind a panel or cover. You may need to unscrew the panel to access it.
2. Unplug the Refrigerator: Always unplug the appliance before attempting to access the internal components.
3. Inspect the Fan: Look for any signs of damage or obstruction to the fan blades. Make sure nothing is interfering with the fan’s ability to turn freely. If ice is built up around the fan it may be an issue with the defrost system.
4. Spin the Fan: Gently spin the fan blades by hand. The fan should turn freely without any resistance. If it’s stiff or difficult to turn, the motor might be faulty.
5. Test the Motor (If Possible): You’ll need a multimeter for this step. Remove the fan motor and access the wiring harness. You can use a multimeter to check if power is reaching the motor (please refer to your refrigerator service manual for proper testing). If there’s power but the fan isn’t working, the motor needs replacement. If you’re not comfortable with using a multimeter, it’s best to consult a technician.
6. Reassemble: If the fan is working, or after replacing it, carefully reassemble the panel and components.
7. Restore Power: Plug the refrigerator back into the power outlet and monitor if the cooling improves.

4. Troubleshooting the Condenser Fan Motor

The condenser fan cools the condenser coils. If it is malfunctioning it will affect the overall cooling of the fridge. It’s usually located at the bottom rear of the refrigerator.

1. Locate the Condenser Fan: This fan is typically located at the back of the refrigerator, near the compressor.
2. Unplug the Refrigerator: Always disconnect the refrigerator from the power outlet before working on any internal components.
3. Inspect the Fan: Check for any obstructions preventing the fan from turning. Remove any debris that may be present. Check if the fan blades appear to be cracked or broken.
4. Spin the Fan: Rotate the fan blades by hand to check if the motor is functioning. It should spin freely, any resistance would indicate a problem.
5. Test the Motor (If Possible): Just like with the evaporator fan, you can test the motor with a multimeter to see if power is reaching it. Refer to your refrigerator service manual for testing instructions. If power is reaching the motor but the motor isn’t working, the motor needs replacement. Consult a technician if you are unsure.
6. Reassemble: Reattach any components you removed and ensure they are secure.
7. Restore Power: Plug the appliance back into the outlet and check if the cooling has improved.

5. Examining the Defrost System

The defrost system prevents excessive ice buildup in the freezer. A malfunctioning defrost system can lead to cooling issues.

This system involves several components, including:

• Defrost Heater: Heats the evaporator coils to melt frost.
• Defrost Thermostat: Senses the temperature of the evaporator coils and activates the heater when needed.
• Defrost Timer/Control Board: Activates the defrost cycle at regular intervals.

Troubleshooting the defrost system requires a bit more technical knowledge. Here’s a general approach:

1. Check for Excessive Frost Buildup: If your freezer has excessive frost buildup (ice all over the freezer) it’s a sign of a potential issue with the defrost system.
2. Unplug the Refrigerator: Disconnect the refrigerator before making any repairs.
3. Locate the Defrost Components: You’ll need to locate the defrost heater, thermostat and control board (usually located behind a panel in the freezer compartment). Refer to your refrigerator service manual for the specific location.
4. Test the Defrost Heater: With a multimeter, you can check the continuity of the heater. If there is no continuity, the heater is faulty and will need to be replaced.
5. Test the Defrost Thermostat: Use a multimeter to check for continuity when the thermostat is cold. It should show continuity when cold. If it does not or when it is warm (room temp), the thermostat needs replacement.
6. Control Board: This can be the trickiest component to diagnose as it controls several refrigerator functions. If the previous steps are successful but the issue persists you should consider consulting a professional.
7. Reassemble: If the issue is with the Defrost heater or thermostat then you can reassemble the components after replacing the faulty one.
8. Restore Power: Plug the appliance back into the outlet and check for improved cooling.

Important Note: Testing defrost components and the control board requires more technical expertise. If you’re not comfortable performing these tests, it’s best to contact a qualified technician.

6. Checking the Start Relay and Overload Protector

The start relay and overload protector are components related to the compressor, that are located on the back of the appliance in the lower section near the compressor. If these are faulty, the compressor may not start or run properly, leading to no cooling. Testing these components requires advanced diagnostic equipment. If there is no clicking sound when the compressor tries to start, they should be tested by a professional or replaced.

7. Compressor Issues

The compressor is the heart of the refrigeration system. If it is faulty then the refrigerator will not cool. If after performing all the checks the unit is not cooling, then the compressor may be faulty. This is a costly and complex repair that should only be performed by a professional.

8. Refrigerant Leaks

If there is a leak in the refrigerant line then the fridge will be unable to cool. A refrigerant leak is generally quite rare and very difficult to diagnose as there are no visible signs unless there is a visible oily residue near the leak. Only a qualified technician can perform a refrigerant leak check and subsequent repair. If you suspect this is the issue, contact a professional.

When to Call a Professional

While many issues can be resolved with the steps outlined above, some problems require professional expertise. Consider calling a qualified technician if:

• You are uncomfortable performing any of the troubleshooting steps.
