The current version of power open / power closed motor used on our dampers is the MA-ND4. The previous two motors, the MA-ND3 and MA-ND3B are similar in design and the same instructions apply.
The replacement is ordered from an EWC Controls distributor as an "MRK" (motor replacement kit). The kit contains an MA-ND4 motor as well as brackets permitting replacement of most of our older, obsolete power open / power closed motors.
