Question about Kenmore 54351 Dehumidifier

1 Answer

Condenser keeps icing up.

Sears 35 pint dehumidifier Model 580.54351 since 2007 has run in our finished basement until now . I have maintained it according to the manual (clean filter and coils) and have a hose hook up to a drain. The problem is that the coils keep icing up and there is no extraction of humid air whatsoever. Also the humidity control switch no longer turns the unit on or off as it used to. I have to unplug the power to it.

In previous years of use in seemed to function just fine. Any advice would be greater appreciated. P.S. It is not one of the Kenmore dehumidifiers with the serial numbers listed for recall.

My 35 pint (42 54351) dehumidifier is only ~2 years old. It will not stay on, even though the basement is very damp. Is there anything I can do?


There are 5 basic, but solvable reasons 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%. If you have an analog unit, set
the humidity extraction knob on 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
problem.

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

Our 580701 70 Pint Low Temp Dehumidifier is just under 5 years old. It is set up with the drain hose connector and has been set this way for several years. We have the humidity level is set at 35%. ...


You seem to have done most of all the right things, so that means the problem may be the basement. Along with a couple of other things. All are totally solvable.

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

2. 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.

3. The hose is partially clogged or the hose connection on the unit and it interior tubing may be
partially clogged. Turn the unit OFF and unplug it.
Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hose connection and tubing. Continue to push it in until you reach a bend in the tubing. You will need to gingerly work the Zip Tie past this bend, until it either bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip Tie back out while rotating (twisting) it. This will breakup any clogs. As you reach the inserted end of the Zip Tie, be prepared, as some water may follow. Reconnect the hose, plug the unit in and turn the Master ON/OFF Switch to ON. Set the humidity extraction level to 35% or Maximum if you have a manually controlled unit. Allow the unit to run, while you monitor it for any leakage.

NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers


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 is failing. 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 helped you troubleshoot and solve the problem. Thanks for choosing FixYa.

Only the fan is running Thanks. Douglas Bisson..


Mr Bisson, there are several things that can casue the problem you have. All of which a usually solved very easily.

1. Dirty or clogged air intake filter. Remove and clean the filter per the manufacturer's instructions. Clean the filter once every two weeks, as part of routine maintenance.

2. The humidity extraction level is set to HIGH. Lower the setting to 35% or lower.

3. Obstructed air flow. Maintain a minimum of 12" clear air space on all sides of the unit, while in operation.

Any or all of the above can cause the problem and are easily solved. I hope this helps to troubleshoot the unit and solve the problem..

Whirlpool DEHUMIDIFIER Model - AD70USS1 does fan NOT does not cycle off anymore in the low settings as it should


According to the Owner's Manual for your model, the fan will run continually, if the unit is set in continuous mode or if the unit is in defrost mode. Once the unit senses a rise in the humidity level, the compressor will start up again. Also, a dirty or clogged air filter will cause the fan to run more that it should.

Hope this helps you troubleshoot and solve the problem.

My machine is running but no water is being collected. The model number on my machine says DE N 500 P


Several things can cause your problem:

Dirty or clogged air intake filter. Remove and clean the filter according to the Owner's Manual instructions.

Dirty coolant coils. Clean and dry the coolant coils.

The humidity extraction level is set to high. Lower the level to 35%

Not enough free air space around the unit. Maintain at least 12" of air space around the entire unit.

The ambient air temperature at floor level is to cold (between 40 - 60 degrees F). Raise the unit up off the floor onto something sturdy enough to handle the weight (including a full tank of water) and the vibration during operation. This happens frequently in basement applications.

Depending on the age of the unit, the refrigeration coolant may need to be recharged.

The humidity sensor has failed and needs to be replaced.

All of the above are where you start troubleshooting and hopefully solving the problem.

The motor runs but no water collects in the bucket. olfi've had it running for hours.. please help. it's only 13 mod p


mempandora, the humidity level that you set on the unit may be to high. In which case the unit will only maintain that level, rather than remove any moisture/humidity. Lower the setting to 35% or minimal, if your unit does not have an LED display. In addition, the air intake filter probably needs cleaning and the coolant coils need to be wiped down and cleaned. The latter is the only part that will require some partial dismantling of the dehumidifier's cabinet. Also, it is imperative, to maintain a minimum of 12" clear air space all around the unit. And finally, the ambient air temperature at floor level may be affecting the operation. If the temperature is between 40 & 60 degrees F, the unit struggles to sense humidity. This is particularly true in a basement. As, the air at the floor is colder than the air temperature.

I hope this helps you to troubleshoot and solve the problem.

Dehumidifier automatic on and off function not working


Unless you live in a dry environment or place the unit in a hermetically sealed room, it probably will not turn off. As the air dries within the room, more moisture comes in with the air. As long as the air outside of the room is more humid than the room this will be true.
