Intermittent Dehumidifier Compressor

Jun 02, 2009 6 Replies

My dehumidifier works sometimes, but other times the compressor doesn't seem to start up. Fan runs when it is supposed to, humid level dial seems to be working, water level switch is ok.



When it runs, the coils get cold, 1 pipe from the compressor gets hot,



1 gets cold (where not covered by insulation) and everything is golden. Other times, sound and fury (fan), but no dehumidification.

I went looking for a relay or something that might be stuck, didn't find one, but did find: "Klixon 4TM" and "Jahwa Positive Temperature Coefficient Thermistor" under a cover on the side of the compressor. The Klixon seems to be an overtemp protection device. The Jahwa thing is a mystery to me. It seems to have something to do with switching the start capacitor in/out of circuit. Do these things fail? Are they available to Joe Average as replacements? Is there a work around?



Any advice appreciated.

Yes, they very commonly fail. Yes, there is a work around. Not sure that the work around is sold to the public. I've serviced a bunch of balky compressors, like that.

Yes, hard start kit. Expensive? Well, that depends. Is a man tall? Is a distance long?

Let us know if Stormy replies. We want to know if there are computers in heaven or hell.
