2 is the shared nuetral for the photo eyes and the wall button. 1 and 2 are for the wall button and 2 and 3 are for the safety sensors. All devices are polarized so keep that in mind. Thanks BB

How do i get the garage door opener to work?


Chamberlain products are polarized so that means even if you have the wires hooked up in the right place they might be backwards. Installing a garage door opener is not really hard but you must follow directions. It should take 4-6 hours if you follow directions. Thanks BB

Wiring the opener and sensors


The wall button gets the red and white wire. The safety eyes use the black and white wires. There are two types of attachments on the back of the openers. One has three screws. On this type the 1 is for the red wire, the 2 is for all white wires, and the 3 is for all black wires. The other type has four blocks and you just match the color to the wire color.
