allseason Posted October 15, 2014 Report Share Posted October 15, 2014 Installed in a 2005 Nordyne furnace in the blower compartment. Capacitor looks like a manufacture date of 2010. Was it installed here as a replacement? Does not look like factory install due to the zip tie. My primary concern is the exposed connections to 120V.

John Dirks Jr Posted October 15, 2014 Report Share Posted October 15, 2014 There should be a safety switch on the blower compartment cover. When you remove the cover, power to the system should be cutoff. If so, there would not be risk of shock. Link to comment Share on other sites More sharing options...
Marc Posted October 15, 2014 Report Share Posted October 15, 2014 Never seen a Nordyne with an original capacitor installed that way, only with metal strapping. Yeah, it's a replacement. Marc Link to comment Share on other sites More sharing options...
Bill Kibbel Posted October 15, 2014 Report Share Posted October 15, 2014 The capacitor mounts to the side of the blower housing. Some techs leave the old one and strap in a new one where it's easy. John - the blower door switch opens the circuit, but doesn't discharge a capacitor! Link to comment Share on other sites More sharing options...

Marc Posted October 15, 2014 Report Share Posted October 15, 2014 It's a small charge, bleeds off to internal leakage in less than a minute. If you're unfortunate enough to be shocked by it, it would likely do no more than take the smile off your face and perhaps send you to the bathroom.

Jerry Simon Posted October 15, 2014 Report Share Posted October 15, 2014 Capacitor discharge, OUCH! 50 years ago, my dad said not to touch the *thingy* on the camera, knowing dam well that you never tell a ten-year-old not to touch something. That old camera had one helluva capacitor. . . Link to comment Share on other sites More sharing options...
Tom Raymond Posted October 16, 2014 Report Share Posted October 16, 2014 My mother has an antique magneto blasting detonator...the wooden box with a tee handle favored by cartoon characters. As teens my brothers and I would take turns holding the terminals while one of us operated the handle. I'm amazed we all survived. Link to comment Share on other sites More sharing options...
plummen Posted October 16, 2014 Report Share Posted October 16, 2014 There should be a safety switch on the blower compartment cover. When you remove the cover, power to the system should be cutoff. If so, there would not be risk of shock. The capacitor stores a charge of 370v normally until its discharged.Fan motor caps are normally oblong,not round. I always wrap the end of cap with tape to isolate the terminals. Link to comment Share on other sites More sharing options...

Marc 370v is normal for furnace blower motor caps and condensing unit caps,some are actually 440v.they are rated by micro farads. that's where the 5/370-10/370 which is common on furnace blowers comes in to play. Condensing units used to separate capacitors back in the day,for example a 5/370 for fan motor and a 30/370 for compressor. Now they use a combination cap like a 5/30/370.

John Kogel Posted October 16, 2014 Report Share Posted October 16, 2014 And capacitors used to be called condensors as in "points and condensor". That reminds me of a time the '52 Chev truck I was riding in died on the way to a job I had to get to. No spark. Hitched a ride to nearby hick town, found an old beater sedan in a guy's back yard, pulled a 'condensor' out of the distributor, hitched a ride back, put it in, off we went.
