NOTE: The 41A5034 Sensors have been discontinued and replaced with 041-0136 Safety Sensor Kit found here
safety sensors on the garage door opener are there to keep the door
from closing on an object, car or person. When they're working they are
great to have but when they stop working they can be a pain. Sometimes
it's just a matter of realigning the sensors or cleaning the lens of the
sensor to get them working again. When that doesn't work it's possible
they've failed and need replaced.
