AS Freedom 80 Blower Motor

I believe the blower motor in my american standard freedom 80 is on its way out. At times the motor will not start up and the burners are shut down by the limit switch. When i open the service panel and spin the blower by hand, its not hanging up or noisy...but after doing this the blower will start up on the next cycle. it'll run ok for a day or so then it wont turn on again. its like there is a dead spot in the motor when it comes to a stop if its in a certain position it wont kick on. at this point i'm 99% sure its the motor but still need to poke it with a multimeter to confirm its getting power when this issue is active. is there a cap in the circuit to help with motor start up?

my main question is where can i buy a new blower/motor unit (if its not a capacitor issue)? Is this a heavily involved DIY? i'm pretty good with this stuff but need to know what i'm getting myself into first.

Replacing the capacitor is worth a try. They are only $5-10 and it might solve the problem.


Replacing the blower motor would probably take you 1-2 hours. The only hard part can be getting the blower wheel off the motor shaft ---sometimes they can be stuck on the motor shaft and hard to get off. But that's maybe 5% of the time.

Generally you have to take the fan assembly pretty thoroughly apart to get the motor and fan wheel out. Just observe carefully how you are doing that so you can reassemble it properly.

The motor can often be adjusted to turn either way. Be sure you have it turning the correct way!
