Safety Sensor Beam Eyes for 41A5034 Liftmaster Sears Chamberlain Craftsman Garage Door Opener (1 Door)

These worked out- I was gambling since the liftmaster was from Aug 1997, and the instruction manual parts indicated 41A4373A for the safety sensor kit, There was no reference in the item description for that part number, and I just wanted people in the same situation to know that they can save the $20+ by getting these over the item that is described as a direct 41A4373A replacement. You do need to switch the wires' coding during connection as everyone else noted, and the brackets we had were on the same side as the LED, which blocked it a bit, but you can still marginally see the light status. As for the push and pray wire connectors, you do need a strong finger push or better yet a pair of pliers to get the connector landed all the way home on the wires, or they will pull out. Use the tips of your strippers to get that orange button seated into the clear body all the way. Good stuff to save my 25 +yr old opener on an 18X7 heavy door. Problem was repeated failure to close especially on cold mornings. door would cycle rapidly at various points of travel and return to open, blinking light, to indicate safety sensor circuit issues. 41A4373A only had 1 green LED on each side that would do nothing to indicate activation, this set has an effective indicator so that you can align the beam/receivers.

Easy to install. Works well with the wires from the old sensor

Este sensor le queda a las marcas que señala el vendedor y a otras cuyo instructivo indique que se conecta en dos entradas (positivo y tierra) del panel del abrepuertas. De fácil conexión por sólo necesitar dos cables cada sensor.

Muy sensibles el emisor y receptor, muy fáciles de instalar. Los recomiendo ampliamente. Espero que la durabilidad sea alta.

Muy bueno. Eso soluciono mi problema y no tuve que gastar en un tecnico. Yo solito los puse y soy bien burro para lo electrico. 1 año despues y siguen funcionando.
