I added some insulation to my wood frame garage door. Needless to say the 1/3rd horsepower opener couldnt cut it any more. I put in a 1/2 hp opener and while it opens just fine now, when it closes it seems like it is slamming closed. It causes the metal track to bow upwards as the door is going down and the whole opener sort of shakes around for a second or two. Is there anyway I can fix this? It appears that with the insulation on the door, it is now too heavy for the opener. Any ideas?
