I just installed a new model 139.53985DM garage door opener. I have the up limit and up force adjustments as far as they will go but the trolley stops well short of the stop bolt. Downward it also seems to go a little further than it should. Will detaching the chain, moving the trolley to the down position and reattaching it correct this?
