Fan stops on Trane XL 1200 starts humming and gets hot. I can pull the fuses
And push them back in sometimes it will start back up. Sometimes I can turn the fan manually until it starts up. At times pecking on the motor will cause it to start up.

Hot motor.

Fan motor is likely failing most usual cause is bad bearings. Possible that the run capacitor is failing, causing the motor to over heat. System looks pretty dirty, if the air passages in the motor are clogged with dust the motor may overheat. When you solve the problem, clean the blower wheel, it pretty dirty and can't move the right amount of air.
