Wipe the fin with a silicone spray or a silicone lubricant on a cloth in late autumn and once or twice through the winter. The film cuts the odds of meltwater bonding the fin to the cold door face, though a hard freeze can still catch it. Avoid oil-based products, which soften vinyl. If the door does freeze to the seal, let the sun or a little warm water free it, dry the spot afterwards, and avoid forcing the opener.

It is better replaced. Lock bars are spring steel, and once one has been bent by an opener pulling against it, it takes a set and tends to bind in its guide or kink again under load. New bar stock is cut to the door's width so the bar reaches through the track with a margin and pulls fully back when released. Both bars are set to the same throw.

An opener is built to guide a balanced door, and every wheel that binds, wobbles or grinds adds resistance it has to overcome across the whole travel. It works harder, runs hotter, and may trip its force limit or reverse partway through a cycle. After roller replacement the technician confirms the door holds its own weight with the opener released, then checks the opener's force setting and its reversal on a test block, since a door that moves freely often needs those settings reduced.

A spring that is intact but has relaxed slightly can be given a little more tension, within limits, to restore balance; this is a normal adjustment on a door that has settled. A spring with a broken coil is replaced as a unit, since the wire has reached the end of its life. The technician checks the condition of the steel and recommends whichever restores a balanced, safe door.
