Question about Electrical Supplies
Hello sue... That activity must have thrown the door out of adjustment.. On the motor unit there are high limit and a low limit adjusting screws. The low limit screw needs to be adjusted to move the door down until it closes properly. Just adjust it 1/4 turn at a time and then test it to see where the door is at. Joe
