Final Step
When everything has been connected to the opener...
Replace the control board access
cover. If you were working with the
opener with the control board access
facing up, remove the opener arm
from both mounts and remount
it in the upright position (control
board cover facing down). Failure
to remount opener in the up right
position will allow water to enter the
opener and cause damage to the
opener control board.
