Sears Craftsman 3/4 HP Garage Door Issue

I bought a 3/4 HP Craftsman Door Opener from Sears on 2/10/09. Installed it a few weeks later. Everything was working ok until yesterday morning. The door opened fine but when I went to close it starts to go down but then reverses and goes back up. The ligths on unit flash 10 times, which according to the manual is a sensor issue. I checked and the Sending Sensor is illuminated but the Receiving sensor is not. I checked the alignment and the sensors are in the same spots that they have always been in since the door was installed a few months ago. I checked my wires and didn't see any signs that they are bad. To be safe I un-connected them and re-connected. The light on Receiving Sensor does not illuminate even after doing this. The only thing I noticed is that when the connections are made with the white and white/black wires if all the wires are touched together then the Sensor lights up. Could it be an issue with the Sensor itself? Tried calling the Support # on the manual but was told they wouldn't talk to me over the phone that they would have to send someone out to take a look at it.

If your sensors are definitely pointed at one another and the light still doesn't come on then it is a bad sensor. The receiving sensor is usually the one to fail. But remember if they aren't pointed at one another the sending unit will still be lit and the receiving light will be out. Tweak them a bit.
