Freezer is too cold and iced over? Here’s what you can do

Sometimes, if your freezer is too cold, the frost build-up can make it difficult to access the food inside it. Freezers are such an integral appliance in our homes, storing food, so it can be kept longer, getting rid of ice cream pints on hot summer days, and more. This article will look at the most common causes of a too-cold freezer and how to solve them.

Quick fixes when your freezer is too cold

The first thing to do when your freezer is too cold is to make sure it’s level. This is especially important for units with a self-defrosting feature, as it needs to be level to operate properly. The second is to make sure it has room to breathe. This means keeping it away from any walls or corners and ensuring there is a minimum of two inches of space between them.

Next, check the cooling settings. If you’re in a colder environment, it’s recommended to keep the settings at a minimum to avoid excessive icing. If the settings appear to be normal, try resetting the unit by unplugging it for five minutes so the compressor can shut off and then plugging it back in.

Common issues when your freezer is too cold

Sometimes the issue isn’t an easy fix and requires further investigation. The three main components that could be the cause when your freezer is too cold are the air damper, temperature sensor, and thermostat control.

A faulty air damper is a common cause of icing. It can be tested by unplugging the power cord, and then manually checking if it opens and closes freely in both directions. If not, it likely needs to be replaced.

The temperature sensor or thermostat is another potential culprit. The thermistor measures the temperature inside the unit, and if it isn’t working correctly, it can lead to the appliance getting too cold. To check it, test the resistance with a multimeter when the freezer is at room temperature. If the readings are not within range, the thermistor needs to be replaced.

The third possible cause could be the thermostat control. This can be tested by running the thermostat knob between its extreme ends and monitoring the freezer’s temperature. If it doesn’t respond to the changes, the thermostat is faulty and needs replacing.

What else can I do to fix my freezer?

If all else fails, you may need to initiate a defrost cycle. To do this, unplug the power cord for five minutes and use a hairdryer or warm cloth to manually break down the ice build-up. Plug the power cord back in and monitor the temperature over the next few hours. If still your freezer is too cold, it’s time to call a professional.

Preventative measures when your freezer is too cold

In areas where the temperature is constantly low, like a basement, it is recommended to keep the cooling settings at a minimum. This is to avoid any excessive icing, which can cause damage to the freezer’s interior.

It is also important to follow any instructions carefully when attempting to fix the freezer yourself. If you don’t feel confident, it is always better to consult a professional rather than risk making the problem worse.

Overall, freezers are appliances that are essential in many households. They tend to give us convenient storage solutions and save us a lot of time in the long run. When your freezer is too cold, it’s important to take swift action and use the tips outlined in this article to troubleshoot and fix the issue.

Expert Tip

Make sure to regularly clean and vacuum the coils on the back of your freezer. This will help ensure the air is flowing freely, and that the cooling settings are not affected.

Keep your freezer clean

It’s also essential to keep your freezer clean. Clean the interior and exterior with a damp cloth, paying special attention to any areas with food leakage or frost build-up. If left uncleaned, it can cause bacteria and fungus growth, which can contaminate your food supply.

Check for blockages

Also, pay attention to any blockages that could be causing the problem. This could be something obstructing the airflow to the freezer. Check the back of the unit for any items blocking the vents, or if there is a filter fitted, clean it if needed.


Check door seals

Another potential issue could be faulty door seals. Check the seals around the door for any signs of wear and tear – any gaps will allow cold air out. This has the effect of the appliance trying to compensate and becoming too cold in other areas. Replace the seal if needed, and make sure the door shuts tightly and securely.

Lower the temperature gradually

If you need to adjust the temperature, do it gradually. This is because sudden changes can cause too much stress on the compressor and other components, leading to further issues down the line.


Store food appropriately

It’s important to store food appropriately in the freezer. Be sure to wrap items like fish, poultry and red meat tightly to prevent any type of contamination. Also, freeze items like fruits and vegetables properly in airtight bags to prevent freezer burn.


Regularly empty and clean ice drawers

Finally, regularly empty and clean the ice drawers which are found on many models. This should also help reduce icing and frost buildup on the freezer’s interior.


Insulation issues and noises

Additionally, if you hear strange noises coming from your freezer it’s a sign of insulation damage. Check for any compressed, broken or missing insulation around the compressor and the fan, and repair or replace as necessary.


Ice makers and water dispensers

If your model has an ice maker or water dispenser, check their components and connections. Make sure they are all securely connected, and the lines are free of blockages. If the lines are blocked, the flow of water to the freezer could be restricted, with the result that the freezer is too cold.


Electrical system issues

Lastly, check the electrical system for any faults. Inspect the power cord for any signs of damage and make sure the outlet is functioning properly. If needed, call an electrician to repair any wiring problems.


Regular maintenance

It’s also recommended to practice regular maintenance on all appliances, including your freezer. Check regularly for any signs of damage, and if one does arise, contact a professional for assistance. This will ensure your freezer runs smoothly for a long time and will help avoid any unnecessary repairs.
