Question about Kenmore Dehumidifiers

1 Answer

Auto-defrost not working at all

I bought a kenmore 70 pint dehumidifier. At 60 to 65 degrees average temp and about 55% relative humidity, I set it to work toward a limit of 40% relative humidity. It works at first for about a couple hours, and then stops pulling water out of the air even though the compressor continues to operate without significant pause. I then leave it off for the night and return to find the 22 pint bucket one fourth full. It seems that the moisture is frosting up into a large block of ice around the coils. This model (99701) says it has an auto defrost feature that turns off the compressor and uses the fan to melt ice. I returned the dehumidifier to sears for another one, thinking it was defective. However, the replacement is doing exactly the same thing. Am I doing something wrong? At the very least, lower operating temperature should cause the unit to work inefficiently as the compressor is put on hold periodically to defrost. The defrost doesn't seem to be working at all and the coils seem to be too cold (frost builds up VERY fast). But for both brand new units?

Unless equipped with special equipment most dehumidifiers will produce little if any water under 65-70 degrees. Many state operation down to 50-60 degrees but this was under lab conditions and therefore a marketing tool. The best performance is gained when the air temperature is above 70 degrees. The water you are finding is from melting frost, if you have a humidity problem you should be adding heat to the area to be dried, warm air holds much more moisture than cold and drying is much more effective if you can heat the area to around 80 degrees.

SOURCE: Dehumidifier Error?

Your bucket full switch may be defective. If you are capable, bypass it since you are draining to another place other than the bucket.

SOURCE: Goldstar DH304 Freezing up / no water in bucket

Thermostat or the temperature control module are not working properly. Also make sure that your fan blades are not broken or warped as this will cause you a problem. Also if the coils have or do get iced up then it will be a low coolant problem. But this is a thermostat or temp control problem

SOURCE: Dehumidifier Error?

Same problem with Goldstar model DH404EY7 -- stop code 01 on startup, bucket full light blinks (drains to floor).

Replaced the main controller board to fix it.

For my model dehumidifer the part # is 6871A20888A, and cost $77.44 (not counting shipping) from Appliance Factory Parts. The Appliance Factory Parts web site also provides parts breakdown (exploded parts diagram) diagrams and service manuals in PDF form.

SOURCE: The coils frost up for Kenmore dehumidifier model 580.53701300

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

Your dehumidifiers are LOW on freon. Over time, small leaks will occur and the coils will freeze. Take your units to a qualified repair shop (central air, or furnace) and recharge the freon.

I have a Kenmore 54701 70 pint dehumidifier about 4/5 years. It has worked well until recently. It is hooked up to a garden hose into a drain. I noticed water was dripping from the housing. The drain is...


Marco, There are 4 things than can cause the problem. All are solvable.

1. The air intake filter is dirty or clogged. Remove and clean the filter if necessary.

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

3. 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.

4. 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.

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.


Hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

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.

The dehumidifier cuts off when it is set on 70% as soon as the compressor cuts on. i can leave it on lo and it runs.


If you're setting the humidity level on 70 % , that means you want to leave the relative humidity in the house at 70%. That's why the dehumidifier is cutting off. Your house is already at 70% humidity or higher. If you want to remove humidity, set the level lower. If your trying to make it cooler in the house or remove a lot of moisture, set it a 35 to 45%.

Hope this helped solve your problem.

When do you use the dehumidifier?


In areas with poor circulation and humidity over 80%.
If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

No water in bucket after running 8 hours. Very clean, no lint or dust anywhere! All settings on the top are correct. Used to work fine and then just one day it stopped completely. Thank you for your time...

yes cycles should be longer either that or the unit is keeping close to desired humidity. Also the unit is under sized 30 pint is for 400sqft. or 20 by 20 room. humidity should be 30/50 percent check your level desired room temp is 70 degrees but its a basemnt 60 works.

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.

Kenmore 54701 (70 pint) dehumidifier stopped running


the lowest setting for % of humidity is 35% on that unit... sounds like with all the other errors that the IC board is bad (the Control circuit board behind the displays)
