Because the operator is protecting the door. Its force setting is tuned to the small effort a balanced door needs, so a seal glued to the concrete by ice registers as an obstruction and the door heads back up rather than ripping the rubber or bowing the top panel. Loosen the seal with a plastic scraper or a hair dryer along the sill, then try again; a shovelled threshold before a cold night keeps it from recurring.
Detached or unheated garage
An operator rated for deep cold, a cold-rated lubricant and sometimes a heavier battery are chosen for a garage that sees winter temperatures, and those choices show in the equipment list.
Top-section reinforcement
Lightweight steel, glazed and wide doors need a strut or operator bracket across the top section before the arm is attached, so the pull is spread across the door rather than concentrated at one point.
Motor rating for the door
An uninsulated single steel door and a heavy double door in insulated steel or solid wood call for different motor ratings, and the heavier door's operator is a larger piece of equipment.
