It’s a common issue among many users that their dehumidifiers ice up. Different factors can cause a dehumidifier to freeze. If you’re facing a similar issue, don’t try to run your unit before addressing it. Otherwise, it may completely damage even high-quality industrial-grade dehumidifiers.
Trying to run your dehumidifier while it's frozen can potentially break it altogether. Don’t worry—you can correct it. But before knowing how to fix this problem, you need to figure out why it happens.
Let’s find out why a dehumidifier ices up.
Why Does a Dehumidifier Ice Up?
As you know, a dehumidifier removes moisture from the air by controlling the temperature. It pulls in warm air, cools it down, condenses the moisture into water droplets, reheats the air, and then releases the dehumidified air back into the room. Whether it’s a crawl space dehumidifier or a small portable one, the basic function is the same.
So, the room temperature, airflow, and components involved in this process all play a key role. A problem with any of these factors can lead to issues such as ice forming around the coils, which can affect the dehumidifier's performance.
- Low Room Temperature
Low room temperature is one of the most common factors that cause a dehumidifier to freeze up. As you know, the coils condense moisture into water droplets that are collected in a tank or pass through the drainage system. This process continues as long as the surrounding temperature is favorable.
If the room temperature drops due to reasons such as running an air conditioner (AC) or cold weather, the water droplets won’t drip into the tank or drain and will start to freeze around the coils. So, you need to make sure the room temperature is favorable for the dehumidifier to function properly.
- Insufficient Airflow
Another reason that leads to ice formation in your dehumidifier is insufficient airflow. If the fan is unable to pull in a sufficient amount of air, it can cause your machine to freeze up. This happens if the fan is malfunctioning or if the machine is positioned in the wrong place.
- Lack of Regular Maintenance
Regular maintenance is highly important for your dehumidifier to work efficiently. Failing to do so can cause problems that include icing up of your machine. If dirt accumulates around the coils, it can cause the water droplets to freeze.
Besides, other factors can also cause a dehumidifier to freeze up. For instance, using a large commercial dehumidifier in a small space with cold conditions can lead to freezing. In such cases, you need to choose a machine that is properly sized for the space and designed to operate in lower temperatures, such as one with an auto-defrost feature.
How to Stop a Dehumidifier from Icing Up?
If your dehumidifier freezes up, here are a few things you need to do:
- Maintain proper temperature
The surrounding temperature of the space where the dehumidifier is placed should be close to the recommended temperature level for your unit. Most dehumidifiers are designed to operate above 65°F. If your room temperature is too low, your unit may ice up. Therefore, you need to ensure the room temperature is favorable for your dehumidifier.
- Ensure good airflow
Your machine won’t function well without proper airflow. Place your dehumidifier in a location where there is no blockage at either the intake or the exhaust. If you’re using a portable dehumidifier, it’s easy to move. However, if you’re using a whole-home dehumidifier, you need to be careful during installation.
- Regular maintenance
Regular maintenance is key to preventing your dehumidifier from icing up. Clean the dehumidifier filter and coils regularly. Make sure to clean each part thoroughly to prevent dirt from accumulating on the coils or restricting airflow, which can cause the unit to freeze up.
4.Choose the right unit
It’s important to choose a dehumidifier that best suits your space. Using a standard portable dehumidifier in harsh, cold conditions, such as crawl spaces or basements, can lead to the unit freezing up. For these conditions, an automatic defrost dehumidifier would be more suitable.
For a standard space like a bedroom, a regular portable dehumidifier will work well. If you need to dehumidify your entire house, consider using a whole-house dehumidifier as part of your HVAC system.
- Defrost your unit
If your unit is frozen, turn it off and unplug it before performing any maintenance. Place it in a warmer space and let it thaw. Leave it for a while until the ice has completely melted. Once the ice has melted, check the coils for any dust buildup. Use a soft brush to clean the coils if needed, as dust can cause your unit to freeze up again.
Conclusion
It is a common issue for dehumidifiers to freeze up due to various reasons. You need to address this problem promptly to avoid any major damage. Don’t run your unit while it’s iced up, as this could potentially break the machine.
The best practice is to unplug it and leave it in a warmer place for some time to allow the ice to melt. Afterward, clean your dehumidifier before running it again. Ensure that you are using a unit that is appropriate for the conditions of your space.
