I've got a Bryant 394G furnace and the blower hesitates to turn at times and I have to manually go and turn the squirrel cage to get the blower to blow the heat through the house,sometimes it will continue to turn on it's own most times I have to go do this at least 3-5 times a day,what's the problem and how do I fix it?:mad:

The centrifugal start switch is bad or the start capacitor is bad. I don't believe the former is used typically on residential HVAC systems.

This assumes that the motor spins freely and the bearings aren't binding.

Sounds like a bad run capacitor to me and a cheap part at that. It may set you back $5 or $10. The motor won't start with out it and if you do get it to start it will over heat.

T-Top:

I re-read his problem and I think it's a little hard to tell from his description if it's the start or run cap. It's probably a dual cap anyway and, of course, it can be replaced with singles.

Start caps - cause the blower to start
Moving the motor shaft manually acts like a start cap

Run caps - cause the blower to run

The heat might turn off/on 5x a day, so that's the reason he goes downstairs (start cap), but then he said sometimes continues to turn which suggests the run cap.

I think we're both partially right.

No start capacitor on that unit only run capacitor.
