After installing the opener, the door must reverse when
it: contacts a 1-1/2" high object (or a 2 x 4 board laid
flat) on the floor. To verify proper operation:
1. Using the wallstation, activate the door to the fully
open position .
2. Place a 2 x 4 board laid flat on the garage floor under
the door path.
3. Activate the door to the closed position with the wallstation. Upon contacting the 2 x 4 board, the door should
stop, then reverse direction within two seconds and travel to the full open position. If the door does not respond
to the required tests, repeat install routine making sure the door is in the fully closed position prior to activation.
If problem persists contact Wayne Dalton Customer Service (888) 827-3667
