If the door just stops on the object, adjust the opener as follows:
The close travel maybe inadequate, Increase close travel limit
by 1/4 turn (See Limit Adjustment on page 17)
Conduct the test again. If the door reverses on contact, remove

seconds
the object and run at least 3 COMPLETE travel cycles to ensure
proper adjustment.
If the door still does not reverse on the object, decrease the
close force (see Force Adjustment on page 18) and repeat the
test.
If the opener still fails the safety reverse test, call a qualified
technician for door adjustment.
