Dead dehumidifier At power up, humidity display says ON and is unresponsive. Restart is no help. There is frost forming on about two tubes worth of the coil. Unit is not pulling water out of the air. Sound like bad brain to you? Worth fixing? daveyk

Pull the bucket out... reach up under the bottom edge of the display bezel and pull down on the back edge to get the filter out; rinse out/off thoroughly, dry and reinstall it...

Get some airflow thru there!

Good Luck!

Westinghouse Heavy Duty 25 Dehumidifier frost on coils


MIKE - I have the same problem...previously, there was NEVER any frost, and the unit worked just fine. Now, all of a sudden in the last week, frost has been forming...water no longer traverses thru the tube into the sink...and the unit is basically useless/

I think when the original person said "frost", they meant ICE!

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.

check the drain tube for blockage, maybe run a small rubber hose to clear out blockage so condensation can drain freely. Worth a try worked for me

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

No 120v to fan motor


It sounds as if this may have electronic controls on it. If so, the problem could be related to too low of an ambient temperature or too low humidity in the air. If this design has a temperature sensor built into it, you may be experiencing "hibernation mode", where the unit will appear to be dead, when it is actually awaiting the proper temperature to employ itself.
The following statement is a parameter for all dehumidifiers and some of the control issues may vary, but the theory is the same.

Dehumidifier frosts up


A dehumidifier will often frost up if room temperatures are colder than about 65 degrees F. If your room temperature isn't this cold, airflow to the unit may be restricted or blocked entirely. 1) Be sure the unit is set far enough from the wall so that airflow isn't restricted. 2) Clean the evaporator coils. To do this, unplug the dehumidifier and take off the outer cover. Allow excess moisture to evaporate from the coils. Then, using a brush attachment on a vacuum cleaner, remove all dust buildup. If necessary, cover the motor and electrical parts with plastic sheeting and spray with water.
