Re: Replacement AC Choice


check schematic to know which color is start winding of motor and goes to the F terminal on the capacitor.

the other from the fan on the same circuit connects to the common terminal.

the cap should have terminals labelled F and H. C/common may not be labelled.

Re: Replacement AC Choice


Okay, I see by looking at the schematic where it goes, but, do I need to be concerned about fidgeting around with the capacitor? I've repaired the wire and put on a new connector, just need to plug it in, but capacitors make me a bit nervous.

Re: Replacement AC Choice


Make sure the capacitor is discharged.

If you want to do things properly, put a bleed resistor across the terminals for 30 seconds, hold with insulated pliers.

If you want to just be quick, short the terminals with a screw-driver you don't care about, short the terminals. if it's charged there will be a spark and loud pop.

Being cheap, i would go for the latter, most do.

Re: Replacement AC Choice


Things are "cool" again, replaced the damaged wire, that didn't do the trick. Replaced the capacitor and all is back in full operating condition. Thanks to all for your generous assistance with this.
