The most common cause why dehumidifiers freeze up is because the room is simply too cold. Even if the machine can operate at a low temperature, it is typically cap at 65°F degrees. Running below the recommended temperature will cause ice to build up on the condenser coils.
How do I stop my dehumidifier from icing up?
Blower Wheel or Fan Blade For proper operation, a dehumidifier needs to have an adequate amount of air blowing across the evaporator and condenser coils to prevent frost or ice buildup. If you feel little or no air coming through the grille area and the filter is clean, then remove the cover and check the fan area.
What happens when dehumidifier freezes up?
A Warning. If your dehumidifier keeps icing up don’t use it! If you continue to operate your dehumidifier while the coils are frosted, you could damage it even further. The motor or compressor unit will be forced to work harder and could get overwhelmed or even burn out.
Should a dehumidifier run constantly?
Should a Dehumidifier Run Constantly? No, there is no need to keep the dehumidifier running constantly. It’s generally enough to run the unit when the humidity level is 50% or higher. A good rule of thumb to remember is to maintain a comfortable 30-50% humidity level for most homes.
Should a dehumidifier have frost?
A dehumidifier should not be operated when the coils are totally frosted over. This condition can result in permanent damage to the compressor which is the heart of the unit and in most cases making it uneconomical to repair.
Do dehumidifiers have refrigerant?
There are a few different types of dehumidifiers out there, but by far the most common are the ones that contain Freon. So, yes, to answer your question dehumidifiers do contain Freon. Most of the Freon branded product from DuPont/Chemours has been phased out due to their Ozone Depletion Potential (ODP).
How do I know if my dehumidifier is low on Freon?
Directly behind the intake filter of your dehumidifier should be the cooling coil (also known as an evaporator). When the dehumidifier is running, this cooling coil should be cool to the touch. If it is not cool, then it is very likely that the refrigerant has leaked out of the system.
How do I clean the coils on my dehumidifier?

Should you run a dehumidifier in winter?
During cold winter months, the air in your home is usually dry, which means a dehumidifier is not necessary. Most dehumidifiers should not be operated in temperatures below 60° F, since the moisture removed from the indoor air can freeze when it condenses on the cooling coils, which can damage the unit.
Can you run a dehumidifier too much?
Turn off the dehumidifier at home. Don’t run it 24 /7. Homeowners need to realize that dry air can cause more harm than humid air. If there is too much dehumidification, say below 30%, it will result in the growth of several bacteria, mold, and dust mites that thrive in low humidity conditions.
What are the disadvantages of a dehumidifier?
Con: Noise and Heat Dehumidifiers also tend to blow warm air out of the back of the unit. In the winter, this can be an advantage — but not so much in the summer. Position the back of your dehumidifier in a doorway so that it doesn’t heat up the room from which you are removing excess moisture.
Why do dehumidifiers have to be upright?

Why is my dehumidifier running but not collecting water?
