craftsman garage door opener

eugene.vandergriftDecember 31, 2007

Took down a garage door opener to replace the worm gear and don't recall how safety optical sensors were wired to the terminals. Model # is 139.53674srt1. There are three terminals, 1 is red, 2 is white, 3 is black. Any help is appreciated.

From each sensor there is a white wire and a white wire with a black tracer. The two white wires go to terminal 2 and the two white with black tracer go to terminal 3.
