I have a Zenith dehumidifier P/N 3850A20500H. It was working, and now its not. I cleaned the air filter, and the fan spins just fine when I spin it by hand. Any suggestions? Thanks, Gary

Gary, if it's not collecting condensation, there are 5 basic, yet solvable reason s for this. One you have already taken care of - cleaning the filter.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit
set the humidity extraction level knob to Maximum.

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

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.

I hope this helps you to further troubleshoot and solve the problem. Thanks for choosing FixYa.

The LG unit turns on but does not run. i have tried to turn DOWN the humidity % but it will not let me go less than 60%. I have cleaned the filter and cleared the drain hose. What else can I do?

Turn the unit OFF and unplug it for 15 minutes.
Then plug the unit back in and turn it ON. During that 15 minute timeout, the unit's electronics may have reset themselves and reverted back to the original factory settings. If it did, you can now set the controls as you like.

Hope this helps you and thanks for choosing FixYa.

We recently purchased a darby dehumidifier-#DDR6009EE-60 pint- and have not been able to program the equip.Can you help us. We need to know how to adjust it so that it will go on and off after specific...

I beleive there is some confusion about the Timer Mode. It can only be set to turn the unit OFF after a selected time period. For example: It's 6pm you want the unit to turn OFF at 10pm. You press the Timer button on the unit itself, in increments, until it reaches 4 hours. At 10pm the unit will turn OFF. As a safety feature, it does not have the capability to turn the unit ON at a selected time and then OFF again. In the interim, until you get really familiar with all the functions of this model, use the control pad on the unit, rather than the remote control.

I hope this helped you understand what the timer does and how to activate & set it.

My LG Dehumidfier 3850A20500H has stopped pulling moisture from the air it still runs but no wataer in the bucket what could be the problem? this starts happening after 1 year of purchase.

There are several things that can cause the problem you described. Most of which are easily remedied.

1. The humidity/moisture extraction level is set to high. Lower it to 35%

2, Air intake filter is dirty or clogged. Remove and clean the filter.

3. Refrigerant coils on the back of the unit are dirty and need to be cleaned.

4. Not enough clear air space around the unit. Maintain at least a minimum of 12" of clear air space all around the unit.

5. Unit is operating in a room that has an ambient air temperature at floor level, of between 40 -60 degrees F. Most dehumidifiers don't work well between those temperatures. Raise the unit up off the floor on to something sturdy enough for the weight of the dehumidifier when the bucket is full.

The above are the top 5 things that can cause a dehumidifier not to work properly. Fortunately, none of the solutions require any major repair to the unit.

Hope this helped you to further troubleshoot and solve the problem.

My Kenmore Dehumidifier Model no. 580.54501400 turns on but I cant adjust anything. It also doesnt collect water or stay on for long. I have cleaned the filter and have done all the simple things so what...

The unit may need to be reset. To do this turn OFF the Master ON/OFF Switch. Unplug the unit from the outlet and wait 12 - 15 minutes. Plug the unit back in and turn the Master ON/OFF Switch to ON. Set your controls as you normally do and if the unit did reset itself, it should work properly. One other thing to take note off, ... Does the unit feel or appear to be overheating? If so, it may need a recharge of refrigerant gas.

Hope this helps you to solve the problem.

Unit was working fine and simply quit. There is power to the unit however it does not turn on there are no lights . The resevoir is not full but the unit does not work

It may simply need to be reset. Turn the Master ON/OFF switch to OFF. Unplug the unit and wait 12 - 15 minutes before plugging it back in. Once its plugged in, turn ON the Master ON/OFF switch and set your controls. If it's not working then .. check the position of the water collection bucket. It may not be tripping the safety switch. Also be sure that the unit is sitting on a level surface.

Hope this helped you to troubleshoot the problem.

Unit will not return to normal operation. Code P1 indicates the unit is in defrost. No frost present on the unit.

The unit may need to be reset. In which case, turn the Master ON/OFF switch to OFF. Unplug the unit for 10 to 12 minutes. Plug it back in, turn the unit ON and set your controls for the humidity you want to remove. This should resent the controls for you.

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

Dehumidifer "froze" Turned unit off removed ice and left for a couple of months. Turned unit on motor works but does not remove moisture.

timer is not working, or thermocouple is defective.
unit must cycle forward-reverse to remove ice, thisis how it works, by melting the ice that forms.

Dedumidifyer stopped working. still plugged in PIN# is 3850A20500h

99% of the time, (if compressor still runs), the fan is stuck with dust, or just needs oiling on BOTH ends of the fan motor shaft.
the other 1% will be because your water reservouir presence sensor/switch is not being activated by incomplete insertion of reservouir, or malfunctioning switch.
