this is a new machine that I had to pull the M3 motor to get a customer up. I reordered part number FK2-6301-000 per the online parts manual, but the motor that came in was larger along with it's mounted circuit board. I check the number again just to make sure, that I ordered the correct part, then I noticed that the connector was the same so figured it must be a manfacturing change. I installed this motor the screw holes lined up the connector went right in, but now I am getting the 0107 about every once in about 40 or 50 pages. The number on the old motor is FK2-6315 but it doesn't come up in ISG as a good number. Any help here would be appreciated.
