Emerson quiet kool dehumidifier 40 frost sentry plus

dehumidifiers remove water from the air. They do not defrost anything.
If you have frost on the unit coils, it may be because the temp is too low (<40°F) or the unit is defective. unplug it till it melts

If your dehumidifier is working it will be extracting water from the atmosphere, into a container that will or should need emptying fairly regularly.
If it is working ok it isn't necessarily going to significantly reduce the humidity in the room as most rooms are connected to the outside world in a number of ways...

The temperature sensor can be broken or because it is an old unit is the freon gas can be escaped by an internal leak in the compressor circuit and thus no longer works, there is a part to be internally freezing when the compressor is running. dismantel to look also if thereis somewhere in the circuit a solenoid-valve to find that will not get dc function by electronica.

The frost is requried for the unit to do it's work. The unit should routinely turn off and the ice should melt. without this process no water would be removed from the air....

Dehumdifiers work by cooling a coil below the dew point temperature of the ambient air. When this happens frost or water will form on the coil. Most room dehumidifiers work with the room temperature above 65 deg F. It works well when the temperature of the room is 65 deg F or higher. But when the temp is below 65, it won't work because the coil does not reach the dew point.

There are cold temperature dehumidifiers that are designed to work in colder environments such as basements. They can work in a environment as cold as 40 deg F. Check your owners manual to see what type of humidifier you have to see what is the minimum operating temperature for you unit. Hope this helps you.

Hi,
When the compressors start to go bad they often start to get very loud also...the cost to replace the compressor will probably be more then a new unit...

My crosley dehum. acted the same way. It turned out to be a bad defrost thermostat on the evaporator coil.

expected? of course! this is not ur solution try draining all the water to the sewerage if u cant try to pump it out with a vacuum cleaner (that can pump water) or a pump then turn on the Dehumidifier every time it frosts turn it off untill it defrosts or u can heat up the basement with a bellower and the Dehumidifier wont frost
