How do I reset the limits on my Liftmaster garage door?

You can use your garage door remote control to program and control the bulk of the motor functions including resetting the open and close limits if the garage door doesn't close or open completely. This can also be done manually on most Liftmaster models. To do this, you will need to locate the limit dials that are on the motor housing.
