If your dehumidifier is freezing up then that probably means it is actually working well. The humidity level in the room is probably just relatively low and you probably have the unit turned up too high for the conditions.

Try turning down the setting on the unit so that it cycles on and off every few hours and does not run continuously.

Also try using some warm soapy water to clean off any dust or oily residue from the cooling coils in the rear of the unit.

The ambient temperature in the room may also be a bit too low, so you can try adding some heat to the room. Since warm air rises, you can even try lifting the unit higher up off the cold floor onto a bench or table where it is warmer.

I don't believe you need a new dehumidifier. Just try a few of the simple tips above and see if it works any better and stops freezing up.

Hope that was helpful, thank you and good luck.

Joe.

New Whirlpool gold dehumidifier last summer. Used since then. It still runs (fan) but no water is being taken from the air. I clean the filters, looked at coils, they are like brand new. I hate to give up,...


Kim, it may simply be a case of the humidity extraction level being set to HIGH. Lower it to 35%. If it's an analog unit (No LED Display) turn the humidity extraction knob to Maximum. More often than not, this will solve the problem. If it doesn't the humidity sensor may need to be replaced.

I hope this helped you and thanks for choosing FixYa.

I just get a dehumidifier it was on all night and the bucket its dry u think theres something wrong with it and whats the % that i have to set it up


% is the % humidity you want.

This is a DEhumidifier for to take water out of air for moist areas.

Usually a setting of 50% or 60% is dry enough. If it is freezing outside, inside of home is probably alreadt below 50%.

If you place in basement below 60 degree, will freeze up. Place over floor drain or in tub and leave off overnight.

What are the settings (humidity)from 40 upwards on my micromark ? . Is the lower setting to take out most moisture ? Thank You


40 is 40% humidity in room - that's really dry.

For moist area you usually want 50 or 60%.

Dehumidifiers are for damp areas. If temp ouside is below freezing, inside house is probably already too low.

What # should I set humidity on/


Perfect humidity is 50% according to conventional wisdom. As far as a number to sit it on ... well you will have to refer to the owners manual.

Dont have one --- contact Haier. I found them to be very helpful, particularly when I wanted a no longer in production machine manual.

It might be that the air you are dehumidifying is already lower than you think. You could measure the humidity independently.

Dehumidifier problem


First, make sure the rectangular filter on the back side is clean so air can flow over the coils freely. Try to place the dehumidifier on a table or something to get it off the floor. (floor level is cooler than head level) If you still have icing issues, replace sensor. (part # WK23X10011 )

Humidity reading is 16% when actual humidity is 46%


Running a dehumidifier when the ambient temperature is to low will cause freeze-ups. Also running it when the dew point of the moisture in the air is to low will cause it to freeze up when you set it to low which would be a higher number on the set point.

The hand written number on the probe casing is probably a quality control inspector number.
