If your garage door doesnt close and the light on the motor blinks, it means the sensor detects something blocking the way. Make sure the two sensors are lined up properly, and that no cobwebs, dust, or other debris are blocking them. If its not shining, the sensor thinks that something is in the way, meaning its either misaligned or blocked. Simply hold down the lock button for a couple of seconds until the green light stops blinking, then try your remote or keypad again.īut they are also easily knocked out of alignment, giving them the false impression that something is in the way.
This light may be located beneath the plastic button, requiring you to pop the button off with a screwdriver. To see if the garage door is locked, have a look at the green LED light on the wall-mounted garage door opener button. If not, unplug the motor and check your circuit breaker if it blew a fuse, flip the switch and plug the motor unit back in.
