garage door opener Craftsman1/2hp

I had to replace the sensors and wires but now I don't remember how they were wired to the unit. There are 3 contacts on the unit numbered 1 to 3. I tried everything but can't get it to work. I got a steady green light on the sender sensor and flashing one on the receiver, tried to align the sensors but the receiver keeps flashing. Can someone tell me which wire goes where? Thank you.


Thank you for reporting this comment. Undo

The white wires go to terminal 2 and the white wires with black tracer go to terminal 3. If the receiving unit is blinking they are probably not aligned properly. Keep tweaking them.
