I removed the panel over it and removed the 4 -3/8" screws which hold it in place leaving the wires hooked up.I then sprayed it with PB Blaster and had my DW run the motor back and forth. I then reinstalled it and tested it.
It now is working like a champ. I too thought my problem was the Battery
but after I replaced battery, but new battery did not solve issue that is when I went to the motor.
