The part is made by LiftMaster and is a direct replacement for the original module. This replacement part from North Shore Commercial Door works for overhead and wall mounted motors.
Itís important to reprogram the travel module after installing the LiftMaster 41D7742-7 replacement part. To program the travel module, refer to the model that came with the garage door opener.

If the door does not raise or lower properly or if it does not stop when an obstruction is present, a replacement travel module may be needed.
