symptoms of a dehumidifier freezing up:

A dehumidifier to freeze up can cause a number of problems, including increased humidity levels and decreased efficiency. Some of the most common symptoms of a dehumidifier freezing up include:

-The unit produces little or no moisture

-There is ice build-up on the coils or inside the unit

-The unit makes loud clicking or buzzing noises

causes for a dehumidifier to freeze up:

If the temperature in the room is too low, the water vapor in the air will condense on the cold coils of the unit and freeze. This can also happen if there is too much humidity in the air for the dehumidifier to handle. In both cases, you’ll need to raise the temperature or turn off the unit until it thaws out.

One possibility for the dehumidifier to freeze up is that this is not getting enough ventilation, causing the coils to freeze over.

or, there is too much moisture in the air, which can cause the compressor to overheat and freeze up.
