• if the door stops on the obstruction, it is not traveling far
enough in the down direction Complete Adjustment
Steps 1 and 2 Programming the Limits and Forces.
NOTE: On a sectional door, make sure limit adjustments
do not force the door arm beyond a straight up and
down position. See Figure 3, page 26.
• Repeat the tesL
• When the door reverses on the 1-1/2" (3.8 cm) board (or
2x4 laid fiat), remove the obstruction and run the opener
through 3 or 4 complete travel cycles to test adjustment,.
• tf the unit continues to fail the Safety Reverse Test, call
for a trained door systems technician
