GARAGE DOOR SAFETY
Because garage doors are the
largest moving objects in our homes, safety should be the primary focus
of maintenance and repair of door and operator systems.
All garage door operators(openers) sold since 1993 have
legally required auto-reverse mechanisms. Older operators lacking these
features should be replaced. In some jurisdictions it is unlawful to repair
an operator that doesn't comply with UL325 (doesn't include and auto-reverse
mechanism). Even where replacement isn't mandated by law, such operators
should be replaced for safety and because their age make them difficult
and costly to repair.
Because extension springs are under extreme tension, they should incorporate
and inserted cable that helps prevent pieces from flying loose if the
most costly repair an owner is likely to encounter with their door system
is replacement of a broken spring. In normal usage, springs will typically
last 5 to 7 years. But breakage is unpredictable- it's impossible to tell
how much a spring life is left by visual inspection.
Other relatively common
repairs include replacement of broken cables, rollers, hinges, operator
photocell safety devices, belts, circuit boards and gear kits. Most of
these repairs can be completed during a service technician's basic call.
