If the humidistat is not working, the compressor will also malfunction and promote coil freezing. Simultaneously, the electric contacts of the humidistat could get fused shut. Disconnect the dehumidifier from the power source and have an expert look into the electric contacts of the humidistat and get them fixed. As aforementioned, the fan is important to regulate seamless flow of air in and out of the device. Check if the fan motor is working correctly by noticing the airflow from the grille area.
A faulty fan motor means faulty fan; which indirectly leads to a device that could freeze. You will be able to judge the fan motor function by listening for the sound and for the speed. If there is a problem with the fan motor, both of these factors will reflect the issue.

Do take a look at this quiet dehumidifier with washable filter if you are looking for a budget friendly lightweight yet powerful dehumidifier. It is recommended that you reduce dehumidifier use in winters, as the humidity will drop when it gets cold or when a heater is in use within the home.
If you have verified that the ambient room temperature is above 65 degrees Fahrenheit, but still the device is unable to pull water from the air; it means you are dealing with a faulty compressor. The overload device in the compressor circuit might be damaged, causing the compressor to also fail.
Yes, a dehumidifier can be stored at low temperatures, but it comes with its own set of challenges. Any water left in the pump or drain tube will be frozen, leading to subsequent unit damage. Dehumidifiers work better at normal room temperatures.
Be it your kitchen or basement, colder weather is ticky for a dehumidifier to handle. If you expect cold weather all year round; it is advised that you look out for models that are designed to withstand harsh climate specifically. Most dehumidifier models that are now available in the market have their own Auto Defrost feature. However, a refrigerant form of dehumidifier does have cooling coils that turn the water content of the air into the water droplets, thereby removing excess moisture from the air.
Since there are cooling coils within refrigerant dehumidifiers, there is the possibility of them freezing up. Refrigerant dehumidifiers , which use coils to remove moisture from the air, can typically work down to around 41 degrees F, but this can depend on the model. Desiccant dehumidifiers , which use absorbent chemicals such as silica gel rather than coils, may not freeze up at all until much lower temperatures. Understanding the reasons behind why a dehumidifier freezes up can help you to figure out how to fix it and how to help prevent it from occurring in the first place.
Airflow is one of the most important factors when considering a dehumidifier that freezes up. If the airflow is not constant, it can lead to problems. You should therefore periodically check all the working parts of a dehumidifier to help prevent it from freezing up.
Consider the following solutions when you discover that your dehumidifier has begun to freeze from use. Remember, proper maintenance done regularly will help prolong the lifespan of your dehumidifier and keep it working efficiently for a long time.
If your dehumidifier freezes and you can fix it, then it is okay to keep using it. The issue arises when the dehumidifier keeps freezing. A faulty bi-metal thermostat may lead to the icing of the coil particularly when the room temperature is low while humidity remains high. This could be due to wiring issues where the electrical contacts that power the compressor circuit is welded shut or a short circuit.
Bi-metal thermostat reads and monitors the temperature of the evaporator coil. Without an accurate reading, the compressor will keep running and the de-icing of the coils will not happen. If there is no whirring noise coming from the dehumidifier, a defective fan motor or blower wheel could be the blame.
A visibly clean air filter is a good sign of a broken fan motor as there is no air flowing through the grille. Additionally, dust, dirt, or debris could also impede the fan from spinning smoothly. This could result in broken or loose fan blades that further restrict the airflow output. A dirty filter clogged with dust, hair, and dirt can result in a frosted dehumidifier due to restricted air circulation. An air filter is there to trap dust particles in the air and protect the internal components.
