If the circuit breaker or GFCI is activated repeatedly, it is a sign that there is a short circuit somewhere in the system, possibly even in the garage door opener itself. Finally, the motor in the garage door opener may have burned out and isn't working at all. If your garage door doesn't seem to respond to any signals you send it, it could be due to several reasons. First, check the batteries in the remote control and keyboard to rule out that they are the source of the problem.
If the batteries are working properly, check the garage door opening unit to see if all the lights are on and working. Otherwise, the motor could be disconnected from the power supply or a fuse might not work. An offline wall switch may seem like the end of the road for your door opener, but it's probably a power problem that can be solved. Because the wall switch is connected directly to the door opener, there is no need to reprogram or fix signal problems.
If the wall switch is broken, most likely the fault is the switch itself or the wiring. To test the cables, detach both of them from the switch and touch them carefully. If the opener responds, the problem may be the switch. If nothing happens, you'll need new cables and you'll need to replace them with an 18 to 22 gauge cable.
When they lose lubrication or become loose, they can cause a click every time the garage door is opened or closed. If the door doesn't move at all, it could mean that the garage door is disconnected from the strap itself. The springs and cables on the garage door can eventually wear out, and broken ones can prevent the door from opening. If the remote control on the garage door opener doesn't work, try new batteries, with a closer range, or reprogramming the remote control.
If your garage door doesn't close completely, but it doesn't turn back either, you might need to adjust something called a limit switch. A leaky garage door seal (also called a weatherstrip) can allow water, insects, dirt, and debris to enter the garage space. The limits are set to tell the door when it should stop closing or opening, so that the engine does not continue to work. Now that you know how to troubleshoot a garage door, it's easy to identify and correct the most common operational issues.
As a safety measure, a garage door opener motor is equipped with switches that specify when the engine should stop when opening and closing. Garages in drier climates or in winter tend to dry out faster or freeze, making it difficult for the garage door to slide down or up along the tracks. If you have a garage door that acts fussy or doesn't respond at all, it can be a frustrating way to start or end your daily commute to work. Fortunately, many common garage door problems have quick solutions that don't require professional assistance.
Garage door openers manufactured after 1993 include sensors to prevent the door from closing for a child or pet. If none of these solutions solve your garage door problems, or if you prefer to have someone else handle the problem, consider hiring a door installer and repair technician to take care of your garage door.
