Won't Power On

Ran the unit one summer without problems. Turned off and unplugged for the winter. When I attempted to turn the unit on the next spring nothing happens. I press the power button and nothing, no lights or anything. Could this be an easy fix I could do? I hate to have it shipped for repairs.

This reply does not solve the problem, however my MAYTAG M7DH
45B2A DEHUMIDIFIER had the same problem.
Circuit Board COR 268BV1.O had circuits burned (on lower side of
board). The circuits that showed signs of arching were the right end
of D1, D 2, D3, D4, and at C2, C3, C4, C5, J1, O1,.
Apparently water must have entered the area and shorted these circuits. But I do not know. The only alternative is to replace circuit
board or junk it

The dehudifier won't come on in and in the digital display the message CH 01 comes up. Any idea what the problem is?

CH 01 usually indicates that the filter is dirty and needs to be removed and cleaned. Turn the unit OFF and unplug it, before removing the filter. Never operate the unit without the filter in place.

I have a whirpool gold 50 pint dehumidifier. Bought in 2009 worked like a charm turned on for the summer the coils are always freezing and not picking up water from the air. Phoned wirlpool they said...

Sonia, There are 5 basic, but solvable reasons for what you described. Please pay particular attention to number 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
cleaning 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
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

Hope this helps you and thanks for choosing FixYa.

Was full - turned off to empty - replaced empty bucket, won'r turn back on and keeps beeping full

Try reinserting the bucket, making sure that it's positioned properly. So that the safety switch is engaged. If that still doesn't solve the problem. Turn the MASTER ON/OFF Switch to OFF and unplug the unit from the wall outlet. Wait 12 - 15 minutes and plug the unit back in. Turn the MASTER ON/OFF Switch to ON and hopefully, if the bucket is positioned properly, the unit will have reset itself.

Hope this helps you to solve the problem. Please let me know.

My dehumidifier says the bucket is full, when it is empty. the red light flashes and it beeps. I can't get any buttons to work. I have taken the bucket in and out several times. Any suggestions? It did...

First, the unit may need to be cleaned and after that, unit may need to be reset. Turn the Master ON/OFF Switch to OFF and unplug the unit for 12-15 minutes. Then plug it back in and turn the Master ON/OFF Switch to ON. Set the controls as you normally do. Hopefully, that 12 - 15 minute timeout, allowed the electronics to reset themselves. If this continues to occur frequently, contact an authorized Frigidaire Service Center

Hope this helps you troubleshoot and solve the problem.

Freezing problwm; very small amount of water was collected.


Here is a tip that I wrote that will help you understand why and what you can do with a dehumidifier that ices up.

Dehumidifier is Freezing up and not working



Kenmore 54701 (70 pt) dehumidifier will not power on.

This unit has had a lot of problems. It has come up in other forums. The fan motor is thermally protected. Could be the printed circuit board is bad. Check out this forum:

Power OFF button doesn't work; unit keeps running, overflows, and doesn't stop

I have the same problem! The "pcb" referred to in the previous reply is undoubtedly what Sears refers to as the "COVER ASSEMBLY, DISPLAY", part number 3551A20109B. It is possible, but highly unlikely, that the defective part is the ESCUTCHEON, p/n 3831A20079D. Sears lists the cost of the COVER ASSEMBLY, DISPLAY as $17.25 plus, undoubtedly shipping and tax. The part seems to be available only from the Sear Web Site under "PArts Direct". This dehumidifier is a piece of garbage. I previously had to replace the SENSOR ASSEMBLY, p/n 6877A30013L. This item turns off the unit when the water tank is full. This dehumidifier has my room flooded - twice - when the unit failed to turn off and overflowed.

While under waranty Sears/Kenmore attempted to repair the unit five times. They never succeeded and when the warranty ran out they would not repair the unit unless I paid for it. Thats when I started doing my own repairs!

Will not power up

it is summer and I just turned on the humidifer. it is dead

No water colledction

Check to see that the air is flowing freely through the dehumidifier. They will accumulate dust particles and become plugged. Also make sure that it is not freezing up (you would see ice forming inside through the vent openings). I have had to remove the case to clean lint from some units to get them to operate more efficently. Always unplug the unit to clean and service it.
