Dehumidifier compressor overheats? and condensor/evaporater clean

I have a Kenmore dehumidifier that is about 5 years old and it starts coming on and less than about a second it shuts back off, then starts coming on in a second or two and continues this a few times, then it may come on and run for a short time. I have taken the cover off and washed out the coils, they looked clean even before washing them. It doesn't help, and the compressor is hot to the touch.

SOURCE: Dehumidifier frosting up

I have the same problem under 5 year warranty. The Authorized May Tag Dealer (Stan & Pauls), advised that they were unable to duplicate the condition. I then took it home, let it run for several hours and brought it to them with the Evaperator completely frozen in ice. They then ran it in their shop and stated that it will not freeze their. It is interesting to note that this model is supposed to detect, icing and shut the compressor off and turn the fan on high for a while. Evidently this feature does not work on mine and can not be repaired. No more Maytags for me.

SOURCE: Haier HDN455 dehumidifier fan runs continuously but not compressor

First ! you are trying to use this dehum in cold weather conditions. this time of the year there is little humidity in the air. best conditions for the dehum to work will be when the temp. is 65 degrees or high, and the humidity is 60% or higher. if you don't trust what I said then take it to sears to be checked out.

SOURCE: LG LD65EL Dehumidifier doesn't work properly

What do you have the humidity level set at on your dehumidifier? The average is 65%. Make sure you do not have it set at 75% because if you do this could be causing it to keep the humidity so high.

SOURCE: Frostguard 36 Dehumidifier runs, but collects no water.

unfortunately it sounds as though your refrigerant leaked out. If your compressor is running and no moisture, this is probably the case. What is the temperature of the air coming out?

SOURCE: compressor does not start

When the compressor tries to start, but only hums and draws a lot of current, the problem is most likely either a bad compressor or a bad run capacitor.

On the Kenmore model 25357510790, the capacitor is a 20 microfarad, 370V oil-filled capacitor, I believe. If you can get one at a reasonable price (around $25-35), it might be worth trying.

If the compressor is bad, the dehumidifier is not economically repairable, if not in warranty. Unless you know someone in the repair business that would do it for you for just the cost of the compressor, that is. ;<)

Other, less likely, problems:

A bad connection (high resistance, say, greater than 2 ohms somewhere in the circuit, including a bad plug or receptacle).

Friedrich dehumidifier

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.

some of these units have a 5 year compressor warranty on them including labor worth calling sears and seeing if it does have the 5 year on the sealed system
