sadly as i feared, the capacitor didnt do the job. Im guessing my next move is to order a new motor? im going to start looking around online but im at a loss for the moment

check the voltage to the motor first. very rare but the board may not be sending 120 volts. remove the wire where it says Heat tap on the board and check from there to ground or neutral after the burner has run for 2 minutes. has a 90 second time delay when it starts. I would remove the fan first and see if you can remove the motor and wheel. it may be seized on and we have special pullers to remove it w/o damaging it. if it won't come loose easily then I would take the whole works to an electric motor shop.

the board shot down fine. ive started the removal process of the blower, i took out the board, and safely removed the condenser, as well as the other wiring around the blower. Tomorrow i am planning on removing the rest and i have a local shop to take to motor to, is there anything in particular that i should watch out for in removing the blower, or anything i should inspect on the motor while i have it out?

Yeah it's always better to try the capacitor first since it's a very cheap part. However from his description I don't think that's it. If the motor was overheating due to a bad capacitor it would stop humming. The fact that it stopped but continues to hum tells me the motor is locked up & still trying to spin. Usually when they overheat they stop making noise.

You can crawl in there on your back and look up at the secondary heat exchanger for wet marks or rust. They had a lot of problems with them failing and a class action lawsuit so Carrier will replace it. Need to get a authorized Carrier dealer to look at it at that point and verify it is leaking and do the work. If it is very dirty you can try clean it also.
