I have an old Dehumidifier compressor. There is three wires, a red a blue and a brown one. I was wondering if anyone knew which one would go to what. Start/Run? Common wire?
Any help would be greatly appreciated, thanks.
Sounds as though you do not have the start capacitor there?
Measure the windings to identify the low resistance run and high(er) resistance run windings.
IOW identify the pair, the higher has the start capacitor in series.
What is the HP, large caps are usually the start caps, which if it is a small motor, does not have, just a run cap which could as small as the one you describe, what is the markings, is it, or was it connected before?
Did you measure the windings?
