I have a problem with the sensors on my craftsman garage door opener, I have tried to disconnect them so that i could operate the door, but to no avail. There are three terminals on the operator, I have my push-button connected to the red and white and the sensor wires disconnected, but the door will not close automatically. You have to hold the wall switch down until the door is closed fully, the remote will only open the door, can anyone help? I do not want to buy replacement sensors if it can be avoided, PS. if anyone has that 1-800 number from the manual it may help.

thanks for any response soon, DataDon

DataDon,
Go and buy the sensor, it's there for a reason. It could save your child's life, your pets life, a scrap on your car or maybe one of your precious tools.
I know I would replace it....

DataDon:

I have to concur with Christopher. Not only are the sensors there for a very good safety reason, they, by design, cannot be disconnected without disabling the opener. Basically, they work by sending a special signal, which is not simply electric current, hence, the inability to disable it.

Since you have them, your opener must be fairly new. The sensors may still be covered under warrantee. I just installed two in my garages, and the 1-800 number for parts is 1-800-366-7278.

Good luck
