Since 1993 garage door openers have been required to be equipped with a safety reversing mechanism. This feature utilizes two sensors about six inches above floor level on both sides of the door. When any object, such as a child or pet, runs through the light beam created by these sensors while the door is closing, the door immediately stops and reverses.If your garage door opener does not have a safety reversing feature, or if the one it does have no longer works, replacing the opener is highly recommended.
Does your garage door opener wake people up or otherwise disrupt the household because it makes so much noise? If so, a new opener will almost certainly be quieter.
Older garage door openers were vulnerable to thieves. Because their remote controls functioned with a fixed code, someone with a special device could sit outside your house and find the code, allowing them to open the garage door.
Older garage door openers did not offer keypads that could be mounted outside the garage. This handy feature allows you to enter a code into the keypad that will open the garage door. No keys required.
One of the big inconveniences of a power outage is often the inability to operate the garage door opener. Garage door openers are now available with battery backup systems that will kick in automatically when you lose electrical power.
