Whirlpool Refrigerator Not Cooling Or Freezing

ByJim Boslice Home & Kitchen

If your unit has stopped chilling, start by checking the condenser coils for dust buildup and ensuring the evaporator fan is spinning freely.

Often, a simple reset or cleaning the airflow path is enough to get your Whirlpool back to proper operating temperatures.

You open your fridge expecting a cold drink, but instead, you are greeted by warm air and the smell of spoiled milk. It is a sinking feeling every homeowner dreads, especially when your kitchen is the heart of your home.

I promise that you do not need to call a high-priced technician immediately. Most cooling failures in these appliances are mechanical issues that a savvy DIYer can diagnose with basic tools and a bit of patience.

In this guide, I will walk you through the diagnostic process to identify why your Whirlpool refrigerator not cooling or freezing properly. We will cover everything from simple airflow obstructions to faulty start relays, helping you get your workshop or kitchen cooler running again.

Understanding why your Whirlpool refrigerator not cooling or freezing

When you notice your fridge acting up, your first instinct might be to panic. However, take a breath and grab a flashlight; we need to look at the “big three” components first.

Most cooling issues stem from restricted airflow, dirty components, or a failure in the defrost cycle. Think of it like a woodworking project—if the dust collection system is clogged, the whole shop suffers.

Your refrigerator relies on a delicate balance of heat exchange. If the coils are insulated by a layer of dust or the fans are obstructed, the system simply cannot shed heat effectively.

Check the condenser coils for debris

The condenser coils are the lungs of your refrigerator. They dissipate the heat removed from the inside of the cabinet out into your kitchen air.

If these coils are covered in pet hair, dust, or shop grit, the compressor will run constantly without actually lowering the temperature. This is the most common reason for a Whirlpool refrigerator not cooling or freezing as expected.

How to clean your coils safely

  1. Unplug the unit to ensure your safety.
  2. Locate the coils, which are typically at the bottom or the back of the unit.
  3. Use a long-handled coil brush and a vacuum with a crevice tool to gently remove debris.
  4. Be careful not to bend the delicate metal fins, as this can impede airflow.

Inspect the evaporator fan and motor

If the condenser coils are clean but the fridge is still warm, move your attention to the freezer section. This is where the magic happens.

The evaporator fan is responsible for circulating cold air from the freezer coils into the refrigerator compartment. If that fan motor is dead or blocked by ice, your fridge section will warm up quickly.

Testing the fan function

Open the freezer door and listen closely. Do you hear a steady hum?

If you don’t hear a fan, manually trigger the door switch. If the fan still doesn’t kick on, you likely have a faulty motor or a wiring issue that needs further inspection.

Troubleshooting the start relay and compressor

Sometimes the heart of the machine is the problem. If the compressor isn’t running, the refrigerant won’t circulate, and you will have no cooling at all.

The start relay is a small device attached to the side of the compressor. It tells the motor when to kick on and helps it get up to speed.

Is the compressor dead?

Locate the compressor at the back of the unit. If it feels extremely hot to the touch or if you hear a clicking sound every few minutes, the start relay may be failing.

You can often test this with a simple multimeter. If the relay rattles when you shake it, the internal contacts are likely fried, and you will need a replacement part.

Evaluating the defrost system

If you see a thick wall of frost building up on the back wall of your freezer, your defrost system has likely failed. This buildup prevents the evaporator fan from pulling air through the coils.

This is a classic issue when a Whirlpool refrigerator not cooling or freezing, as the ice acts like a blanket, keeping the cold air trapped behind the panel.

Checking the defrost heater

  • Remove the back panel inside the freezer to expose the evaporator coils.
  • If you see heavy ice accumulation, the defrost heater, thermostat, or timer is likely the culprit.
  • Test the heater for continuity using your multimeter; if it doesn’t show a closed circuit, it needs to be swapped out.

Frequently Asked Questions About Whirlpool refrigerator not cooling or freezing

How long should I wait after cleaning the coils to see a change?

Give the unit about 24 hours to stabilize. It takes time for the internal temperature to drop once the compressor begins running efficiently again.

Can a dirty air filter cause cooling issues?

Yes, if your model has an air filter, a clog can restrict airflow. Check your manual and replace the filter if it hasn’t been changed in the last six months.

What if I hear a loud noise coming from the back?

That is usually a sign of a failing fan motor. If the blades are hitting ice or the bearings are shot, the fan will struggle to move air, leading to a loss of cooling performance.

Is it worth fixing an older Whirlpool fridge?

If the compressor is functional, most parts like relays, fans, and thermostats are affordable and easy to replace. It is almost always more cost-effective to repair these components than to buy a new unit.

Final thoughts for the workshop DIYer

Troubleshooting a Whirlpool refrigerator not cooling or freezing is a rewarding project that saves you hundreds in service calls. By taking a methodical, step-by-step approach, you can identify whether the issue is simple maintenance or a failed electrical component.

Remember to always prioritize safety by unplugging your appliance before you start poking around the electrical components. Treat this like any other repair in your shop—keep your workspace organized, use the right tools, and don’t rush the process.

You have the skills to get this back in working order. Grab your multimeter, clear out that dust, and get your kitchen running smoothly again. You’ve got this!
