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
