Fedder dehumidifier model fad25
Posted 18 July 2006 - 09:18 AM
After installing the replacement pieces the fan starts and then the compressor makes a 'click' like it is going to run, but it doesn't run. This repeats every few seconds. I doen't know what to do next. It isn't the bucket full switch because when it is full the fan won't run. This is a very basic older unit with no computers.
Any help with troubleshooting this unit would be appreciated.

Thanks for your help.

Yep. The transformer thingy is the start relay 4 the comp, and because the comps are so small they sell them together as 1 piece. As Nick said this may not be worth the repair cost.
Check out my last post to apphlp about his dehumidifier. I explain how to test the capacitors out, but is sure shoulds like UR compresasor is shot:(
Hope this helps:)

Boyyyyy, that must B an oldie but a goodie of a meter:). U might want to be careful with that thing. I'd B curious to hear how U hook it up to read amperage? Most of todays meters can read up to 600 amps, some 1000. If u exceed the rating of the meter, it could go on melt down, so BBBB careful.
No, U can't check amps on a capacitor. U can only check amps on a load. eg: a fan motor,compressor. Something that uses electrical energy.
I think the meter U have would be usefull in checking ur unit. Check the FLA-full load amps-- rating of each device on the name plate of the unit. When running U should read close to FLA of the fan and commpressor.
Were U able to do any of the continuity checks yet? Let me know how U make out:)

I did all of the continuity checks before coming to this board. Everything checked out after I installed the new humidistat and capacitor.

Sorry, 30+ yrs & I've always had a clamp on. Forgot U could measure AC/DC that way. Thought it was only DC.
Since U've done alot of checking already then yeah I think the 2 last things to check R that U have the 115VAC?? on the 2 wires feeding out to the compressor(I'm assuming its 115VAC unit and there R only 2 wires feeding out 2 it, before the start relay) and the amp draw of the compressor it's self.
U might want 2 take the start relay out( make a drawing of the wiring) and take it to a refrigeration supply house 2 C if they can match U up with 1 if the amperage test comes out way high, before changing out the compressor.
Hope this helps:)
