580.53701300 low temp dehumidifier freezes up, no water, fan & compressor run constantly in basement 61 deg. F. Has sensor been declared defective and will Sears remedy by free installation & labor for improved sensor assembly?

IIt may very well be that the the air intake filter needs to be removed and cleaned. But, before doing this, turn the unit OFF & unplug it. Allow the unit to completely thaw, before removing the filter.Never operate the unit without the filter in place, As this could damage the unit.

Hope this helps you & thanks for choosing FixYa.

Barbara, are you running the unit in a continuous mode (i.e Using a hose to drain the unit)? Or is the water draining into the water collection bucket?

If you are not using a hose for continual drainage, the fan will not run constantly. It requires that, for continual operation.

Also, you may have the humidity extraction level set to high. Lower it to 35%. Also, remove and check the air intake filter, as it may need cleaning.

Dehumidifiers that are not Low Temp models have a difficult time operating in basement applications. Because the air temp at floor level is colder than at shoulder level. At temperatures between 40 & 60 degree F, regular dehumidifiers struggle to keep up. Raising it up off the flow on to a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water can really help.

I hope this was of assistance and thanks for choosing FixYa.

After the unit is totally thawed and dried, turn the unit Off if you haven't already and unplug it. Remove the filter and clean it. If it's really dirty wash it with warm water and dish washing liquid, thoroughly rinse it and allow it to completely dry, before reinstalling. DO NOT operate the unit without the filter in place.

Because the air temperature in a basement is colder at floor level, than at shoulder level, this caused the coils to freeze. Dehumidifiers do not work well at temperatures at or below 60 degrees F. That is, unless, it's a Low Temperature model, designed especially for basement applications. Obviously, yours isn't a Low Temp model.

To overcome this, place the unit up on a sturdy table, counter top, etc, that can handle the weight of the unit, as well as a full bucket of water. The higher off the floor the better. This way, the ambient operational temperature will be higher and the coils will have less of chance to freeze again.

I would suggest that continue to monitor the unit and if you notice that it's doing more than a little frosting on the coils, turn the unit OFF immediately. A little frosting is normal and the deforst mode should kick in and thaw the coils. When this happens, the compressor should automatically shut OFF, but the fan will continue to run. Once it's defrosted, the compressor will start again, if necessary.

I hope this helped you to troubleshoot and solve the problem. Please let me know.

Turn the Master ON/OFF Switch to OFF, unplug the unit and allow it to thaw out completely. You may want to put some old towels under it, to absorb the dripping water. Once it has completely thawed, remove the bucket, the air intake filter and the face of the cabinet. You should now have access to the coils. Clean them with a mild soap and warm water. Rinse and thoroughly dry the coils. Once they are totally dry, spray a very light film of WD40 on the coils and then wipe off any over spray. Reinstall all the remove parts and test the unit.

Keep in mind, if you are using the dehumidifier in a basement, the air temperature at floor level is colder than at chest level. Dehumidifiers don't work well between 40 & 60 degrees F. (Unless, they are a low temp unit). Any lower, the coils will freeze. Raise the unit up off the floor onto a sturdy table or counter top, that can hold the weight of the unit plus, a full tank of water. In a basement application, doing usually solves the problem of freezing coils.

If after doing all the above, the coils still freeze during operation, the compressor may below on freon and needs to be recharged. Or the defrost sensor on the unit, needs to be replaced.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

is compressor running fan maybe compressor must be running for dehum to take the compressor has a distint sound should be easy to tell by sound

you are low on the freon charge you need to take to a service shop
were they can charge it.

A Dehumidifier will not cool your basement, just make it seem cooler at the same temp. Your dehumidifier may be undersized even for that purpose.

You need an AC outlet of a central AC in your basement, or a window unit if there are windows.

Warm air at discharge is normal.

most likley low on freeon gets colder when it leaks out stat could be not working correctly

Most dehumidiers have a "Frost Guard" thermal protector on the condensor coil. This protector will turn the compressor off should the temperature fall below 65 degrees in the basement. The condensor fan will still continue to run anticipating the restart of the compressor.
Hence, 3 things could be wrong.
1. air temp.of basement is too cold
2. Frost guard could be faulty
3. Freon leak in condensor coil.
Assuring that basement temp. is above 65 degrees is about all you can do unless you have it checked out by a technician.
