Temperature in the room

The temperature in your area and room is one of the most common reasons why do dehumidifiers freeze up?. The majority of the dehumidifiers can work well at 65 degrees and above. But when the temperature goes down below this, a dehumidifier may start icing up. Sometimes it may stop working. The air comes in through a vent and after that, it passes through metal coils. The water present in the air condenses and it drops into the bucket. In some cases, this is pumped away using a hose.

This system works well when the temperature is in the standard range. But when it is too cold water starts freezing up on the coil rather condensing. This situation can lead to issues.

Flow of Air

In some cases, airflow can be the issue for dehumidifier freeze up. In this case, the cause can be due to the improper working of the fan. In some cases, it can also be due to the condenser unit. If the condenser unit is blocked, then the air may not pass through properly in the machine. If you are ensuring regular maintenance then you will not face these issues.
