Same problem with mine. Just pulled the thing apart ...and they were nice enough to have a schematic right behind the water bucket. In my case I found the defrost switch was open. If you pull the back off it's located in the lower right corner clipped to the compressor pipe and covered with a black insulating putty. It has two large red wires coming out of it as well, quite obvious. I unclipped mine and tapped it a few times and it closed up - so now the compressor will come on ...but I'd like to get a known good one in there. I just found this site was I was trying to find the part. If anyone knows where to get one please post! PN: 37TA32 501624 F57-20F J0332 Thanks! - Pat

Try gently tapping the compressor a few times -use a wooden stick or similar to avoid damage -sometimes that is all that's needed. There are however many other possible reasons for a compressor not to start - most have their own fuse/controller assembly (sometimes this is very obvious inside the case, often a car spade type fuse which is worth checking visually), and there are cut-outs that will stop the compressor if it is low on gas, although usually it will start first for a few seconds if this is the case. Sorry, but the (www.maytagair.com) website is down at the moment, but try it again later and you should find their troubleshooting and support is good. Hope this helps :)

How do I determine reason that my Danby Dehumidifier isn't cycling on to compressor for more than 3-4 seconds at a time? Fan always runs but compressor only kicks in for 3-4 seconds then back off.


I would say low on gas or bad switch/thermostat.
The compressor probably has a shutoff for low freon. You would need a set of gauges to check for that.
Bad thermostat? You'd need a ohm meter.
User error? What kinda settings or controls do you have on the control panel?
There was a recall on these in 2014 for catching on fire.

Sounds like the compressor is inoperative. Most, if not all new units have no means of recharging the freon if it leaks out. If the coils are not cooling, the compressor is not operating and the unit will not dehumidify.

My Santa Fe compact dehumidifier in my crawlspace makes a noise (not a smooth humming sound but more of a harsh vibrating sound) when it is not dehumidifying. I can turn the knob to the dryest setting and...


The black cylinder is the compressor. It sounds like your unit is cycling the compressor for some reason. If the compressor starts, runs fine, and removes water when you set the humidity control to the driest setting the compressor is probably OK and the problem may be with the humidity control causing the dehumidifier to "short cycle" for some reason. You may need to change the humidity control or relocate the dehumidifier in your crawl space.
If the compressor attempts to start, and then sits quiet for 10 minutes, and then attempts to start again, you have a problem with the dehumidifier. There are a few things that can cause this problem:
Low refrigerant charge
Bad compressor capacitor
Bad compressor overload
Plugged capillary tube or broken expansion valve
are the common causes of this behavior. If you suspect one of these problems, call the factory service department at 1-800-533-7533 for help.

Good luck with your dehumidiifer.

Kenmore 54701 (70 pt) dehumidifier is not prerforming properly


could be a bad humidistat or a bad PTC relay on the compressor, check for voltage going to compressor, and check neutral continuity, if there is both then you have a bad compressor, check warranty on comp replacement, if no voltage then the humidistat is probably bad
