How to Fix Whirlpool Refrigerator Freezing Up: Quick Guide

At times, having to face issues with our daily necessity machines can be really frustrating. Especially when it comes to essential daily necessities such as our refrigerator. 

The refrigerator freezing up can be a real problem. 

You would really be anxious to get them freshened as soon as possible.  . 

How to fix Whirlpool refrigerator freezing up?

To address the Whirlpool refrigerator freezing up issue, you should investigate the temperature controlling thermostat. Also, if there is any leakage at the door gasket, it might also cause the problem. So, check for leakage with paper currency. Also, check the defrost heater, thermostat, and timer. 

Still worried after getting the brief? Don’t worry too much. I have dedicated an entire segment addressing this issue below. 

Why wait? Read along!

Why Does Your Whirlpool Refrigerator Freeze Up

One of the classic deductions behind a Whirlpool refrigerator freezing is the temperature controlling thermostat. You need to check the thermostat to determine if it’s working properly. The procedure you will need to follow is to rotate the thermostat from low to high. A clicking sound will ensure it’s properly working . 

Affirm that the thermostat is working with a multimeter if the click is not heard. Check for the continuity of the thermostat. If you can’t find the continuity, you might need to replace the thermostat. 

You can program a thermostat as well. The temperature control thermostat directs sufficient voltage to the compressor. 

If the thermostat is broken, the refrigerant can not run properly. Hence, the refrigerator demonstrates the issue of freezing up.

Another deduction could be the air damper controlling assembly. The damper automatically closes and opens to let enough cold air enter the refrigerator. 

If it remains open, an unnecessary amount of cold air will enter. This will lead to the refrigerator freezing up more quickly. 

You need to check the air damper if you see it open. Or, even if you find it slightly open, replace it. 

Things to Check Before Fixing!

If you see your Whirlpool refrigerator freezing up, don’t panic! You can fix them without being too exhausted. I have accumulated some of the methods for you; 

But initially, you have to confirm you have enough information about a few things.

First, you need to be sure of the temperature of your refrigerator. To have your refrigerator working properly, you need to set it at the right place. 

The recommended temperature is between 33 degrees to 39 degrees Fahrenheit. Set the temperature somewhere in between. 

You must not set the refrigerator temperature below 33 degrees. Otherwise, the drained water freezes and clogs the fridge compartments. 

Also, drain heaters not functioning can be another issue. Assure the correct continuity with the multimeter. If the continuity is not set right, then replace the heater.

It will keep the drained water from freezing and clogging the drain. 

How to Fix Your Whirlpool Refrigerator from Freezing Up

Even if you know the solution sometimes, you don’t know how to fix them. Understand and attempt the given fixes for your refrigerator to see if they work;  

Door gaskets

You might find leakage at your door gaskets at times. Use a paper currency to determine this. 

Put the currency in between your door and refrigerator unit. Then close the door. After completing that, hold the currency with your hand. Then attempt to pull the currency out. If you fail to pull the currency out then your door gasket is working fine. 

And if you can pull the currency out then your gasket is broken. You should immediately replace it. 

If there is leakage at your door gasket, then the outside air gets in. Which condenses and freezes resulting in the refrigerator freezing up. 

Defrost System 

Also, essentially affirm that the defrost time, defrost thermostat or the defrost heater are operating correctly. If they are broken then your refrigerator might freeze up. 

You can use a screwdriver to determine the defrost timer. Turn the timer slowly with the screwdriver. Keep on turning the timer until you hear a click sound. Upon hearing a clicking sound, the compressor and the fan will halt operating. 

If your heater and thermostat are working properly, the heater will keep on working. And if your hater is working then your timer is broken. 

Next, to determine if the thermostat is not broken you will need a multimeter. The multimeter will accurately determine the continuity. 

Fun fact, you can use the multimeter to check engine ignition as well. So, having one nearby is very useful. 

If you find continuity with your multimeter then your thermostat is working properly. You don’t need to worry about that. And in case of not finding any continuity, the thermostat has been broken. 

The thermostat turns on the defrost heater. Immediately install a new one if it’s broken. Because without the thermostat, your defrost heater will not turn on. 

Hence, your refrigerator will keep on freezing up. 

The defrost heater will be your final concern. The defrost heater is responsible for not letting the refrigerator excessively heat up. You will again need to use the multimeter. 

Like previously, check the continuity. 

If you don’t find any, then the defrost heater is broken. You should replace the defrost heater straight away. 

If you’re thinking about buying a multimeter for your refrigerator. You can give the given below, multimeters a try. They are really good at their job:


These are some of the really good multimeters. Also, they are really versatile. So they can be used for various purposes.

Air Vents 

Often we open and shut the refrigerator door too frequently. Always keep in mind air vents in your refrigerator should always be open. 

If it’s blocked then you will face the issues arising. Also, don’t open and shut the door too often. And keeping the door open for a longer duration causes the same effect. 

If the humidity is too high, use a humidifier where you kept the refrigerator. Make sure that too much outside air is not getting inside the refrigerator. 

These are some of the methods you can use to fix your issue. 

But, if you are uncertain about the procedure, always contact a professional. They will be able to give you more accurate results and solutions. 


Question: Why is my fridge icing up at the back? 

Answer: This problem usually happens if too much outside air enters the fridge. As a result, frost builds up and starts icing at the back. Try not to have the door open for too long to avoid this problem. 

Question: Why does my fridge have ice build-up? 

Answer: If you’re facing this issue then, there might be a problem with the door seal or hinges. Check the door gasket for any sort of leakage. If you find any, replace the gasket as soon as possible. 

Question: Why does my Whirlpool refrigerator keep freezing up?

Answer: The best temperature for your refrigerator is between 38-40 degrees Fahrenheit. If your food is constantly freezing then it might be an issue with the temperature. It can be set too low accidentally, keep it at the optimum temperature for best performance. 


So that’s all from my end. I hope you’re now clear on why your Whirlpool refrigerator freezing up. And how you can solve them. 

It’s a task related to electricity. Follow safety instructions as required. It’s better not to deal with any lethal consequences. Additionally, always contact a professional if you are not certain. 

That’s it for today. Until next time, have a beautiful day!
