Force setting. Test the force setting of the opener by holding the bottom of the door as it closes. If the door does not reverse as you apply moderate resistance, the setting is probably excessive.
Reversing test. Place a 2-by-4 block on the flat in the path of the door. If it does not promptly reverse on hitting the block, you should repair a modern opener or replace an older one that lacks the reversing feature.
