Craftsman Garage Door Opener Sensor Problem

I have a 13 year-old Craftsman garage door opener which keeps reversing when I try to close it. The green light is off on the receiving sensor so the door thinks there is something obstructing it. The sensor light doesn't come on no matter how much aligning I do. I verified that there is power getting to the receiving sensor. Do these sensors sometimes go bad? How can I test the sensor? Thanks for any help.

Yes they go bad. Really I don't think there is any test other than disconnecting and moving them right up to each other, but if it won't work in the normal position, that won't help you much.

Some Lowes and HD sell Chamberlain sensors, which should be compatible, though the mounting may be different. You can also find them online pretty cheaply.

It may not be the sensor, but its likely. Does the door go down if you push and hold the wall button?

Thanks for the info. Yes, the door will close if I push and hold the button. I suspected it was the sensor after I verified the wiring was OK. I'll see if I can pick up a new sensor.

I went to lowes and on the pacage it said for models from 1993-present. Mine is a 1992, will it still work? Any ideas.

Can't give you a positive answer. Unless someone else can, I'd suggest calling the maker of the opener. There may be no real change between the 92 and 93 models.

Check to make sure you wired the new sensors correctly. The wires are color coded. One is solid white and the other is white with a black stripe. The solid white wires go to terminal 2 and the white with black stripe go to terminal 3.

If you still have the old receiving sensor that worked you should try it.

They came with 36" wires and connectors. I didn't have to unwire from unit. Wired it up wh/wh and blk stripe /to blk stripe, no go. I will send back because my unit was mfg in 1992 or earlier.
