| | Automatic Garage Door Openers (Site not responding. Last check: ) |
 | | If the door fails to immediately stop and reverse when it strikes the wood, disconnect the opener and use the door manually until the system can be repaired or replaced. |
 | | Consequently, a new law as of January 1, 1993, requires that a garage door opener must be equipped with a monitored non-contact safety reversing device or safety edge that stops and reverses a closing garage door. |
 | | If the opener is operating, but the door doesn't open, it may be due to a worn gear or chain drive sprocket, a broken chain, or the door has disengaged from the operator. |
