I have a Carrier Air Handler (FV48NF003000AAAA) inside the house. The blower motor will no longer start. It is possible that over the last several weeks it may have been starting and shutting off but I can't be sure. The fan spins freely but there is a humming and the cage gets very warm. I didn't touch the actual motor so it may be that the heat strips were warming up the cage.
Anyway, a tech came in with 2 motor testers which were supposed to eliminate everything outside of motor itself. It would not start. He then ohmed the motor at the connector and got a bad result (don't know the exact readings). Is there a way to tell if it is the motor itself or the ecm on the back of it? I removed the cage and the back of the motor. Everything looks good visually. There is some white goop between two capacitors but it looks like spillage from another component that was used to mount the other component. My costs, motor with ecm =about $, ECM by itself about $.
Also, is it normally necessary to use a pulley puller to remove the motor shaft from the fan?
