My blower motor (in the furnace compartment) stopped running the other day, the out side unit runs fine. A service tech found that the high speed wire was loose and reconnected. He also found the motor was running a little hot after a few minutes of operation, said that may have caused the connection to loosen from excessive heat. The next afternoon the motor stopped again, I check connection and it still doesnt run. I pulled the assembly and the motor spins freely and doesnt have any "electrical smell" , it is about 8 years old.
Question, could the run capacitor be the issue and is it likely the motor went bad and still spins freely? Also being in Las Vegas the motor deals with heat from running and an attic that is about 170 degrees , any specific brand of motors that deal with extremes better?
