Hello Brian this is Scott, is the other furnace functioning normally?
Hey Scott - yes the other system is fully functional
is there any chance that the blower motor in the unit in question got wet?
Brian I seem to have issues with chat did you responde to the question did the motor get wet?
Hey Phil -
Thanks. Interesting you raise the point of the wire connections to the capacitor.
As I was switching out the capacitor yesterday it looked like one of the wires was a bit frayed between the wire and the spade connector.
I went back up to the attic this morning to look at it. It did seem like a weak connection. I didn't have another spade connector on hand, so I just cut off the connector stripped the wire and threaded through one of the eye holes on the capacitor. When I first powered up the fan came right on, but did not hit full speed. I powered down and tried to tighten the wire connection. Second time I powered up the fan did not start. Powered down, gave the fan a spin and powered up. The fan started but again did not hit speed. I'll run out this am and get a spade connector.
Naturally, we're having the hottest weather of the summer this year - Mid-Atlantic area between Balto and DC. So if I need a new motor, I'd want to order as quickly as possible. Based on what I've described, do you think it is unlikely the motor has failed? Given it spins freely and runs?
Ok - thanks. I'll be working the wire later this morning and let you know.
BTW - the motor/system is about 15 yrs old. If that is a factor in your assessment.
Sounds like I couldn't go wrong replacing the blower motor - even if it just ends up as a wire issue at this time? Any suggestions for determining the specific motor - without removing the motor?
I've got the manual - the unit is a Ruud UGDG or UGDJ. I replaced the motor in my other unit and have a note that it was a 3/4 horsepower motor - but I don't see any other notes on it.
