Goldstar Dehumidifier Compressor Won't Run


I have a Goldstar DH40 40-pint portable whose compressor has stopped running.

The unit still powers up and the fan runs, but the compressor doesn't kick in.

I checked the humidistat with a voltmeter and there is variation in the ohms reading, so it appears to be functional. When I disconnect the humidistat from the board, still no compressor run (although I don't know if that simply "opens" the contact and keeps it from firing up.)

I pulled the board and checked the quality of the solder joints on the back for the relay and transformer. Both appear very sound; the whole boards looks very good.

Now I'm wondering if it's the capacitor, or the start relay itself, but I don't know how to check those.

The unit is 10 years old and cost about $200. It replaced another 40-pint Airtemp unit which cost $200 and did the same thing (compressor stopped firing up) after about 6 years of use. (That one is collecting dust under the basement stairs, thinking it's going to get fixed, too!)

Should I just accept that these things are disposable, ie., not worth the time/parts to fix? Seems so wasteful, since every other aspect of the machine seems sound, to chuck it because some $1 or $2 electrical component fails.

Advice please. Basement if getting a bit damp and wifey is ready to go shopping...

Almost impossible to find any schematics or wiring diagrams on these units.

You should have two wires to the compressor.... do they have 120vac on them ?
