Jim Katen 148 Posted January 14 Report Share Posted January 14 One of my partners snapped this picture of an unconnected capacitor in a 2013 furnace. My best guess is that the manufacturer uses one shroud for both its cap blowers and its non-cap blowers. Any other insights? Quote Link to post Share on other sites

Jim Katen 148 Posted January 15 Author Report Share Posted January 15 Sorry. I just added the picture. Quote Link to post Share on other sites
Marc 86 Posted January 15 Report Share Posted January 15 I don't recall ever seeing a blower with other than a capacitor-start motor. That unconnected capacitor is a mystery to me. Quote Link to post Share on other sites
John Kogel 35 Posted January 15 Report Share Posted January 15 My guess is that the motor has a cap mounted on it, a replacement maybe, need pics. Quote Link to post Share on other sites

Ya know, it might be that an original capacitor-start motor was replaced with an ECM motor. ECMs don't use capacitors, they're 'electronically commutated', if that makes any sense. If that were true, the control circuitry would need to be replaced also. Quote Link to post Share on other sites
Jim Katen 148 Posted January 16 Author Report Share Posted January 16 Perhaps. Or maybe the manufacturer was putting together a furnace with an ECM motor and they just slapped on the wrong shroud one day - or maybe the cap had already been installed on a shroud and someone forgot to take it off.
