Generally they freeze up for two reasons. very low humidity or the temperature in the room is too cool

for low humidity it's best to cycle the dehumifier (so it goes off occasionally) using the control for it.

for temperature you may have to use a heater or warm up the room in some fashion.

most likely the reasons for it starting to do that is a season change of low humidity/cooler weather.

Heat exchanger line frosting up. Then drips on the floor


The condensate bucket may be missing or installed incorrectly. In some dehumidifiers poor design causes condensate to drip onto the floor.

Why doesn't water drain into the hose?


My dehumidifier was dumping condensate onto the floor instead of through the hose to the floor drain. The solution turned out to be making sure the unit was level. No worries since then.

Haier 45-pint dehumidifier unit cannot be turned on. It has been running fine last few days.


The first thing that comes to mind, is have you emptied the water collection bucket recently? If so, be sure that the bucket was properly reinstalled and is making contact with the bucket safety removal switch.

If you haven't emptied the bucket in the past few days, it may simply be full and will not start until it's emptied.

Hope this helped you and thanks for choosing FixYa.

I have a 45 pint haier dehumidifier that is plugged in, everything lights up, but doesn't run. What's the deal?


There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.
Hope this helps to troubleshoot & solve the problem. Please let e know.

Runs constantly and will freeze up the coils. Will not stop compressor to allow the coils to thaw.


You are taking too big a bite out of your humidity at one time ... plade the adjustment on a higher setting for now. When youe machine has achieved that goad, ower the setting a bit.

Alternatively, set a small fan to blow more room air on the coils ... you will probably still have to adjust the stting higher ...

I have a brand new Haier 45 pint Dehumidifier. The manual gives no advice on setting temperatures. What do I do? I set up with hose going in to my sump pump but no water seems to come out


Most of the time you set @55% RH. But on most Portable dehumidifiers you dont have a setting that tell you percent. Set about 1/2 way and see how much water it put out. That is about 60%. Go from there. Rus
