Why Your Dehumidifier Keeps Icing Up

One of the most common problems that many homeowners experience is when a dehumidifier ices up, particularly in areas that are not well-ventilated or in colder climates. 

Not only does the dehumidifier stop serving its purpose any longer when it’s freezing, but it may also have long-term impacts on the machine.

In this guide, you will learn the possible causes of this issue, its solutions, and some of the best Creworks dehumidifiers that can avoid such issues completely.

7 Reasons Why Your Dehumidifier Is Icing Up

A dehumidifier is aimed at drawing moisture out of the air. However, it may begin to freeze when the conditions are not so good. The most probable reasons are these:

1. Room Temperature is Too Low: When the temperature in the room is lower than 65°F (18 °C), the cold coils within the dehumidifier may become iced rather than filled with water.

2. The Air Filter Is Dirty: Dust and debris limit the airflow that causes the coils to become excessively cold and freeze.

3. Air Circulation is Poor: When your dehumidifier is too near the walls and furniture or other objects, then it will not have sufficient air flow to run well.

4. Faulty Humidistat: The icing up can occur when the humidistat fails to work properly, and the unit might run longer than intended.

5. Low Refrigerant Levels: Similar to an air conditioner, dehumidifiers use refrigerants. Coils may freeze in a short time in case of leakage or a deficit.

6. The Dehumidifier is Oversized for the Space: The dehumidifier that is oversized will not cycle correctly, and this, at times, leads to freezing.

7. Ongoing movement in cold basements or crawl spaces: These spaces often have high humidity but also cooler temperatures, making them prime spots for icing problems.

What To Do When Your Dehumidifier Freezes Up

When your dehumidifier continues to freeze, the following are the actions you can take to remedy the situation:

1. Turn Off and Defrost: Never leave the unit on; always empty the ice and then turn it back on.

2. Check the Temperature: Make sure that the space is 65°F and above. Otherwise, think about relocating the dehumidifier to a place that is warmer or using a space heater.

3. Clean the Filter: Clean the air filter from debris and dust every now and then to ensure smooth airflow.

4. Reposition the Unit: Your dehumidifier should not be less than 6-12 inches away in order to move well around walls or large furniture.

5. Check Refrigerant Problems. In case you suspect a leak in the refrigerant, then you'd better request a technician to come and examine the unit.

6. Run on Auto Mode. Many contemporary dehumidifiers also have an automatic mode that eliminates overworking and the chances of freezing.

7. Size Appropriately. Ensure the dehumidifier is the ideal size for your area.

Top 3 Dehumidifiers From Creworks to Prevent Icing Issues

The selection of a proper dehumidifier can be the solution to avoiding icing issues. These are three great Creworks dehumidifiers created to be efficient, reliable, and performance-driven:

This dehumidifier is a 130-pint-per-day model, which is compact and powerful and can be used in crawl spaces, basements, and warehouses. 

Its robust design guarantees it will last long before use, and efficient moisture extraction will ensure the coil does not overwork, a situation that will result in icing up.

 It has easy-to-use controls and a simple drainage facility, making it a viable solution to residential and light commercial spaces.

2. 145 PPD Commercial Dehumidifier with Water Pump

Fitted in basements, garages, crawl spaces, and warehouses, the unit has a built-in water pump to drain continuously, 145 pints per day. 

That is, you will not need to worry about emptying buckets manually. 

It has good airflow and dehumidification effectiveness that helps to maintain constant humidity levels, making it less likely to have a freezing dehumidifier even in demanding surroundings.

3. 180 PPD Commercial Dehumidifier with Built-in Pump & Hose

This 180-pint is the final one to be selected in large and humid areas. 

It has an in-built pump and hose to ensure easy drainage, hence ideal in warehouses, flood recovery, and in industries. Its rugged design guarantees constant operation without danger of icing, even when it is at full capacity. 

You can resort to it when you want maximum efficiency and reliability.

Frequently Asked Questions About Dehumidifier Freezing Up

Why is my dehumidifier freezing up so often?

Probably, low temperature in the room, restricted airflow, or a dirty filter. The problem can be reduced with the help of regular maintenance.

1. Are there possibilities of a frozen dehumidifier becoming damaged?

Yes. Turning on a dehumidifier when it is frozen may break the compressor and coils, resulting in expensive repairs.

2. What can I do to prevent my dehumidifier from freezing in a basement?

Ensure that the basement remains at a temperature of more than 65°F, have the filter washed periodically, and use a dehumidifier with an auto defrost feature.

3. What should I do with my freezing dehumidifier: repair or replace?

When it is a minor adjustment, such as cleaning or rearranging, fix it. However, when refrigerant leaks or significant mechanical problems are at stake, it is usually better to replace it with a high-quality one at Creworks.

Final Thoughts

A dehumidifier freezing up is frustrating, but by understanding the causes and applying the right fixes, you can keep your unit running smoothly. And when your older model simply isn't working, it can save time and headaches to invest in a quality Creworks dehumidifier.
