I am troubleshooting my Craftsman garage door opener, how can i bypass the safety sensors?

Answer 1

I mount my censors near the opener so that they are 4" apart from each other, that way they can see each other.
You cannot bypass the system, they have to see each other, maybe get some more wire, unmount them and place them next to each other, and use the wire as extension cords.

Answer 2

Every Craftsman built since 1992 must have the sensors connected and able to see each other in order for the opener to go through the closing cycle normally (they have no effect at all during the opening cycle). If you think you've got a sensor issue, try cutting the wires to the sensors leaving about 8 inches of wire from each, bring them up to the motor, wire directly to the terminals. If you point them at each other and they both light up, then the sensors are fine. If they don't light up, then you need to replace your sensors. If they work at the motor, but didn't seem to work when they were at the bottom of the doorway, then you probably have a broken or shorted wire somewhere between the overhead motor and the sensors. Replace it with 22 gauge wire. To close your door even when you have a sensor problem, press and hold the hardwired button on the wall inside the garage. The opener will close the door as long as you hold pressure.
