non working automatic garage door
i am dealing with a delta 3 linear digital control automatic garage door. everything is installed already and when the button is pushed, the unit makes noise, but nothing happens. the chain is in place etc but i am wondering if there is supposed to be some sort of belt on the unit. it looks like one would go on the bottom of the unit, but i cant find any information on the specific model.
