Short answer: Check the thermostat settings and ensure proper airflow. If issues persist, inspect the compressor and evaporator fan.

Whirlpool, a globally recognized brand known for its home appliances, offers a range of freezers designed to efficiently preserve food. However, like any appliance, Whirlpool freezers can sometimes encounter issues, one of the most common being the inability to maintain the desired freezing temperature. The issue could stem from various factors including thermostat settings, airflow restrictions, or more serious mechanical problems such as issues with the compressor or evaporator fan. Understanding the potential causes and solutions for this problem can help users ensure the longevity and efficiency of their freezers.

Why Whirlpool Freezer Is Not Freezing?

Whirlpool Freezer Not Cold Enough? Problem Solved!

The fridge is overloaded:

Overloading the freezer can restrict airflow, preventing the unit from cooling properly. It’s essential to ensure there’s enough space between items for air to circulate.

Incorrect thermostat setting:

If the thermostat is accidentally set to a warmer setting or malfunctions, it can prevent the freezer from reaching freezing temperatures.

Excessive frost buildup:

Over time, frost can accumulate on the freezer’s evaporator coils, hindering their cooling capability. When the coils are covered with a thick layer of frost, they can’t absorb heat effectively, which reduces the freezing capability.

Failing door seals:

Door seals ensure that cold air remains inside and warm air stays out. If they’re damaged or failing, the freezer can lose its cold air, leading to a decrease in freezing capability.

Dirty condenser coils:

The condenser coils release heat from the freezer. If they’re covered in dust or dirt, they cannot dissipate heat effectively, causing the freezer to work harder and possibly not freeze properly.

Failed condenser fan motor:

This fan helps circulate the air over the condenser coils. If it’s not working, the coils might not cool down as they should, impacting the freezer’s ability to freeze.

Temperature control board fail:

This board regulates the power to the compressor and evaporator fan. If it fails, it might not send power where it’s needed, causing cooling problems.

Faulty compressor:

The compressor is like the heart of the freezer, circulating refrigerant between the evaporator and condenser coils. If it fails, the entire freezing process is affected.

Main control board failure:

This is the brain of the appliance. If it fails, it can affect various components, including those crucial for the freezing process.

Low refrigerant levels:

The refrigerant is vital for cooling. If levels are low (possibly due to a leak), the freezer won’t cool effectively.

Power supply issue:

If there’s an inconsistent or weak power supply, the freezer might not get the power it needs to function at its optimal capacity, causing freezing issues.

Dirty Condenser Coils Fix:

Step 1: Unplug the freezer.

Step 2: Locate the condenser coils, usually found at the back or underneath the appliance.

Step 3: Using a coil brush or vacuum with a brush attachment, gently clean the coils to remove any accumulated dust or debris.

Step 4: Plug the freezer back in and monitor its cooling performance.

Faulty Thermostat Fix:

Step 1: Unplug the freezer.

Step 2: Access the thermostat, usually located inside the freezer compartment.

Step 3: Test the thermostat using a multimeter for continuity. If it doesn’t have continuity when turning the temperature knob, it’s defective and needs replacement.

Step 4: Replace the faulty thermostat and reassemble the freezer.

Door Seal Issues Fix:

Step 1: Inspect the door seals for any visible damage or wear.

Step 2: Clean the seals with a mild detergent and warm water, ensuring they’re free of food debris or sticky substances.

Step 3: If the seals are damaged, they need to be replaced. Usually, they can be pulled off and new ones can be pressed into place.

Lack of Overflow Fix:

Step 1: Regularly check and ensure that the freezer isn’t overloaded.

Step 2: Reorganize the contents, ensuring that air can circulate freely.

Step 3: Avoid stacking items too closely together.

Dirty Evaporator Coils Fix:

Step 1: Unplug the freezer.

Step 2: Access the inside panel of the freezer where the evaporator coils are located.

Step 3: Using a brush or vacuum, gently clean the coils.

Step 4: Reassemble the freezer and plug it back in.

Fix Faulty Defrost System:

Step 1: If there’s excessive frost buildup, manually defrost the freezer by unplugging it and letting the ice melt.

Step 2: Check the defrost timer, thermostat, and heater for any malfunctions. If any component is defective, replace it.

Fix Power Supply:

Step 1: Ensure that the freezer is connected to a working outlet.

Step 2: Check the power cord for any visible damage.

Step 3: If using an extension, ensure it’s of the right capacity and not causing voltage drops.

Change the Water Filter:

Step 1: Locate the water filter, usually found at the bottom or inside the fridge section.

Step 2: Turn off the water supply.

Step 3: Remove the old filter by turning it counterclockwise (or following the manufacturer’s instructions).

Step 4: Insert the new filter and turn it clockwise until it locks into place.

Step 5: Turn the water supply back on and check for any leaks.


How often should my Whirlpool freezer go into a defrost cycle?

Typically, modern freezers go into a defrost cycle every 6-8 hours, lasting for about 30 minutes. If it’s more frequent, there may be an issue with the defrost timer or system.

What should the ideal temperature setting be for my Whirlpool freezer?

The recommended temperature for a freezer is 0°F (-18°C). Always use a thermometer to check the internal temperature to ensure it’s at the desired setting.

Can a faulty Whirlpool freezer affect the refrigerator section too?

Yes, in many combined fridge-freezer models, if the freezer isn’t cooling adequately, it might also affect the temperature of the refrigerator section.

Is it normal for the exterior walls of my Whirlpool freezer to feel warm?

Yes, it can be normal. The sides of the freezer have built-in coils that release heat, so it might feel warm to the touch. However, if it’s excessively hot, there might be an issue.

Do I need to manually defrost my Whirlpool freezer?

Many modern Whirlpool freezers come with an auto-defrost feature. However, if you notice excessive frost buildup, it might be beneficial to manually defrost it.

How long can I expect my Whirlpool freezer to last?

With proper maintenance, most freezers, including Whirlpool brands, can last anywhere from 12-20 years.

The interior light of my Whirlpool freezer isn’t working. What should I do?

First, check if the bulb has burned out and needs replacing. If a new bulb doesn’t work either, there may be an electrical issue or a problem with the door switch.


A Whirlpool freezer not freezing can be attributed to a myriad of factors, ranging from simple issues such as incorrect thermostat settings to more complex ones like compressor malfunctions. Timely identification and resolution of these problems are imperative to ensure food safety and to maximize the lifespan of the appliance. Regular maintenance, such as cleaning the coils and checking door seals, can prevent many of these issues from arising. However, if confronted with persistent or unfamiliar problems, seeking professional assistance is always a wise decision. Ensuring the optimal performance of your freezer not only guarantees the longevity of your stored food but also the long-term functionality and efficiency of your appliance.
