Many households rely on refrigerators for storing perishable items. It’s a problem when the KitchenAid refrigerator suddenly stops cooling. There could be various reasons why this happens, but most issues can be fixed quickly and easily.

We will discuss these causes and offer practical solutions to restore your refrigerator’s optimal performance, including maintaining the correct refrigerator temperature, in this blog post.

KitchenAid Refrigerator Not Cooling

KitchenAid Refrigerator Not Cooling 

When a KitchenAid refrigerator suddenly stops cooling, it can signal one or more underlying issues. These may include dirty condenser coils, malfunctioning evaporators, faulty evaporator fans, problems with the compressor relay, or defective condenser fans. It could also be attributed to incorrect temperature control settings, faulty gasket seals, or clogged defrost drains. While some of these problems can be resolved with a trusty screwdriver, others may require the expertise of a professional.

Before reaching for that screwdriver, let’s cover all our bases to ensure the solution isn’t an obvious one. From there, we’ll systematically work through the potential fixes.

Temperature Settings Matter: The settings that control how cold your fridge is are really important. If you change them, it will affect how well your fridge works.

The Right Temperature: It’s best to keep your fridge between 33°F and 40°F. If it’s any warmer, your fridge, freezer, and ice maker might not work properly.

Adjusting the Temperature: If you find the temperature is too high, you can fix it. Just lower the settings for both the fridge and the freezer. Remember, they might have separate controls, so check both.

Checking Over Time: As time goes on, it’s a good idea to make sure the temperature is still right. Sometimes, fridges can start to get warmer or cooler. To check, you can put a special thermometer inside your fridge for a week. If the reading is too high or too low, adjust the temperature settings.

Clean the Condenser Coils

This should help your fridge work better! If you need to, you can do this again in the future. Just remember to unplug it first.

Make Sure the Condenser Fan Is Working Properly

Make Sure the Condenser Fan Is Working Properly

Condenser Fan’s Job: Your fridge has a fan that’s pretty easy to spot. It’s usually found between some important parts called the condenser coils and the compressor. What it does is simple: it keeps those parts cool by blowing fresh air over them.

What Happens If It’s Not Okay: If this fan stops working or gets blocked, your whole fridge can have problems, and it won’t cool properly.

When It Should Start: When you turn on your fridge, this fan should start spinning by itself, and it keeps spinning as long as the fridge is on.

Checking for Issues: If the fan doesn’t start spinning when you turn on your fridge, there might be a problem. First, take a look at the fan’s blades to see if there’s anything blocking them. If they look clear but still won’t spin, try giving them a gentle push to get them going.

If It Still Doesn’t Work: If none of that works, it’s possible that the fan’s motor isn’t working properly, and you might need to replace it. Also, if the fan blades look rusty or worn out, you might need to get new ones.

So, in simple terms, make sure the fan is spinning and doesn’t have any issues. If it’s not working right, you might need to replace some parts. This helps keep your fridge running cool!

Examine the Start Relay

Check the Start Relay: After making sure the fan is working, the next thing to look at is the start relay. It’s a part near the fan, connected to the big machine called the compressor. It’s in charge of turning on the compressor.

What It Does: Think of it like a switch for the compressor. If it doesn’t work, the compressor won’t turn on, and your fridge won’t cool properly.

How to Check It: Turn on your fridge and touch the compressor. If it’s working right, you’ll feel it moving or hear a buzzing noise. If there’s no movement or buzzing, the start relay might be the problem.

Checking the Start Relay: Unplug your fridge and carefully take out the start relay. Give it a little shake. If you hear rattling or see bits falling out, it means the relay is broken and you’ll need a new one.

Listening for a Click: Another way to check is by listening. When you turn on your fridge, if you hear a click from the compressor followed by another click turning it off, it means the start relay is likely the issue.

So, in simple words, if the compressor isn’t starting up, the start relay might be the culprit. You can listen for a click or check by touching the compressor. If it’s not working right, you might need to replace the start relay. This helps your fridge cool properly!

Verify that the Evaporator Fan Is Working

Verify that the Evaporator Fan Is Working

Check the Evaporator Fan: This is a fan that helps keep your fridge cool. It’s in the front part of your fridge.

What It Does: The fan pulls in cold air and spreads it around your fridge. It first cools the freezer and then the main part where you keep your food. If this fan isn’t working right, the cool air won’t spread properly.

How to Tell If It’s Not Working: If your freezer is cold enough but the main part of the fridge isn’t, it might mean this fan needs to be replaced.

One or Two Fans: Some KitchenAid fridges have one fan, and others have two. The newer ones usually have two – one in the freezer and one in the main part. The older ones usually just have one in the freezer.

How to Check: Just listen. If it’s working, you should be able to hear it.

In simple terms, if you think the fan in the front of your fridge isn’t working, you might need to get it replaced. You can tell by listening if it’s running properly. This helps your fridge stay nice and cool!

For Refrigerators with a Single Evaporator

For Refrigerators with Dual Evaporators

So, whether you have one or two cooling systems, if the fan isn’t working, you might need to replace it. You can test it by using the door switch. It’s essential for keeping your fridge cool.

Examine the Evaporator(s)

If previous solutions and checks are done and the fridge is still not working, focus on the evaporator. It’s a set of tubes behind the freezer panel that produces cold air. Newer models have dual evaporators for better control. If the fridge is warm but the freezer is cold, a faulty evaporator fan motor might be the issue. Also, ensure the temperature control thermostat is functioning.

Use a multimeter to check the compressor. If it fails, consider replacement. If it passes, consider replacing the main control board.

Inspect the Defrost Drain

Why it’s Important: Your fridge has many parts that work together. If one part has a problem, it can affect the others. In your fridge, there are coils that make things cold, and a heater that stops ice from building up on them.

What Happens When it Defrosts: Sometimes, the heater melts ice and it turns into water. Normally, this water goes into a special drain in your fridge.

When the Drain Gets Blocked: But sometimes, this drain can get blocked. This happens when things like dirt or bits of food get in the way. When this happens, the heater can’t melt all the ice, and it builds up.

What Extra Ice Means: Too much ice can make your fridge not work right. It won’t be as cold as it should be.

How to Fix it:

So, if your fridge isn’t cooling properly, a blocked drain might be the reason. You can fix it by clearing the drain. If you’re not sure how to do it, it’s best to ask a professional for help. They’ll know what to do safely.

For Refrigerators with a Single Evaporator

In traditional KitchenAid refrigerators equipped with a single evaporator, the defrost drain is located in the freezer, beneath the evaporator coils.

For Refrigerators with Dual Evaporators

In dual evaporator refrigerators, the defrost drain can be found in the refrigerator section, directly under the evaporator coils.
