How do you wire the garage door opener for sensors and for remote control?
I have a Craftsman 1/3 HP garage door opener, model 139.53335SRT. The unit had a worm gear replaced. It has optical sensors and remote opener. How should the wires be connected on the Opener Terminal screws? There are 3 terminals: 1 is red, 2 is white, 3 is black. The only wires currently going to it are from the optical sensors. The wires were not labeled before they were removed.

The wires to the door sensors should be 2 white wires and 2 white with a black stripe. the wires to the wall switch should be red and white.
- Put the red wire to the wall switch on terminal 1-red.
- Put the white wire to the wall switch and the 2 white wires to the door sensors on terminal 2-white.
