Check to make sure it is wired correctly. Solid white wire from each sensor to terminal #2 and white wire with black tracer to terminal #3. Also check to make sure the wires aren't broken or shorted by staples.

My Craftsman garage door opener opens fine. It


It could be closing too far or the sensitivity could be set too sensitive.

Lube the springs, wd-40 rust may be the whole problem.

If the door hits and the opener continues to move until the rail flexes upward and then reverses - probably the travel adjustment.

Does the door close and stay closed if you hold the wall button down constant until it closes? - this would indicate a safety eye problem.

If the door reverses before it hits the floor or just as it hits the floor it could be the sensitivity or if the safety eyes are mounted to the track they could be flexing enough to move the eyes out of alignment.

Hope this helps.

How do i conect the low volt wire ( the safty eye and the button wire)?


The terminals on the rear of the motor unit are both numbered and color coded. The white wire with the red stripe from the wall control goes to terminal 1. The solid white wire goes to terminal 2. The 2 white wires with the black stripe from the sensors go to terminal 3 and the 2 solid white wires go to terminal 2. You should end up with 1 wire on terminal 1, 3 wires on terminal 2 and 2 wires on terminal 3.
