What Can Cause a Dehumidifier to Ice Up?
A dehumidifier can ice up for several reasons. One common cause is a low temperature in the room. If the room temperature is too cold, the moisture in the air can freeze on the coils of the dehumidifier. For example, if you place a dehumidifier in a basement or a cold storage area where the temperature is close to or below the dew point temperature of the air, ice is likely to form.
Another factor is improper air circulation. When the air cannot flow freely around the dehumidifier, the cold surface of the coils doesn't get enough warm air to keep the moisture from freezing. This can happen if the dehumidifier is placed too close to a wall or in a corner where air movement is restricted.
A malfunctioning thermostat can also lead to icing. If the thermostat is not working correctly, it may not accurately sense the temperature and humidity levels. As a result, the dehumidifier may keep running even when it should stop, causing the coils to become too cold and ice to form.
Dirty or clogged filters are yet another culprit. When the filters are dirty, the airflow is restricted. This reduced airflow can cause the dehumidifier to work harder and cool down more than it should, resulting in ice buildup.
Question 1: Can a dehumidifier ice up because of a dirty filter? Answer: Yes, a dirty or clogged filter can restrict airflow. This makes the dehumidifier work harder and cool too much, which can cause ice to build up on the coils.
Question 2: Does low room temperature always cause a dehumidifier to ice up? Answer: Not always, but low room temperature near or below the dew point temperature of the air is a common cause. If the air is cold enough, moisture can freeze on the dehumidifier's coils.
