Question about Haier 45-Pint Dehumidifier

1 Answer

New dehumidifier runs very hot...back of unit is extremely hot to the touch, and the space around it becomes uncomfortable to live in. With hot summers like this one (and maybe future ones?) we don't need it any warmer! Also...there doesn't seem to be any difference between "high" and "low" fan speeds. Shouldn't you be able to hear a difference?

Has there been a recall on this product? My compressor seems to run but no water is collected. I took the back cover off and the compressor is extremely hot and I know that other Amana dehumidifiers were...

Your description indicates a loss of refrigerant in the dehumidifier. The metal heat exchanger above the water collector should become cold when the compressor is running - if it does not, your dehumidifier likely has lost it's refrigerant charge. You will have to take it to a certified (refrigerant handling) technician to repair. It may make more sense to replace with a new dehumidifier.

Check the CPSC website for dehumidifier recalls. they will have details of the brands/models/serial numbers of recalled units.

Fan runs but compressor does not come on or stay on long enough to reduce desired humidity level

Three things can cause the problem you're having:

1. A dirty or clogged air intake filter.

2. The humidity extraction level (percentage) is set to high. Lower it to 35%. Or minimal if you don't have an LED display.

3. Not enough clear air space around the unit. Maintain a minimum of 12" clear space around the entire unit.

Number 1, should become a part of a every two week routine maintenance program.

Hope this helped you solve the problem. Please let me know. Thanks.

Dehumidifier is leaking from the bottom,also for a brand new home what should it be set at and should in run constantly or only at certain times?

Yes it should if it is a window unit. How long it runs depends on how much room space you want cooled and what size unit you have. If you live in an area that has high humidity you will want it to run more often to remove the humidity. Some units have a setting so that it is running all the time to circulate air, but the compressor is only on when the air is too warm.

My dehumidifer collect water but the fan blows hot her so it makes the room hotter

This may be caused by running the unit in continuous mode, rather than timed mode. The heat is generally is generated when the defrost mode cycles on, to defrost the cooling coils. This happens more frequently, if the air space around the unit is obstructed or it's operating in a temperature range of 40 to 60 F. Cleaning the air intake filter at least once a week, can help solve this problem, too.

Maintain a minimum of 12" free air space around all sides of the dehumidifier. Use a timed mode rather than a continuous mode. Make sure the room is within the proper operating temperature range and clean the air intake filter weekly.

Hope this helped you troubleshoot and solve the problem.

The dehumidifier isn't taking the moisture out of the air.

is the compressor in the unit hot to the touch,or are the coils freezing and thawing when it runs<if so you probably need to add some R-134a refrigerant,these type of units are notorious for losing all or part of their refrigerant charge,but unless you have the equipment to remove old refrigerant and vacuum the system down and recharge it it can get costly

Dehumidifier problems


Might it be that the unit simply needs a full thorough cleaning including the tiny spaces between fins? Dust can gather and block air passage on many of the components of a dehumidifier not only on the filter. in some extreme cases, the unit could be undercharged (insufficient) coolant. A service shop engaged in the business of cleaning and repairing air conditioners should also be able to work on your unit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
