Got the circulating pump motor up and running - found out after church that there's a separate furnace (forced air) for the sanctuary. And of course, the blower motor's a 3Ø... behind an access panel in the basement.

Got power going to it, but it doesn't run. D?C'd it from the line, ohmmetered it, and have no resistance between phases - a little resistance shows if I maually spin the motor, but hard to read and spin at the same time. No contiuity to the case on any lead.

I'm a resi & light commercial spark - not a big motor guy - HELP!

Other than the fact that the inside "looks melty" (dig my technical jargon [Linked Image] ), it's not as badly scorched on the outside as the circ motor was. And since it's bigger (7.5 HP v. 3/4 HP) and significantly heavier, I can't just pull it out for a look see.

Any help is appreciated,

Doug
