Garage door opener problem
I have a Chamberlain Whisper Drive garage door opener. The sensors are malfunctioning. The one with the yellow light is solid like it should be. But no matter what I do, I can't get the green light to stay lit. At best, there is a barely noticeable flicker that still prevents the door from closing.

The door doesn't move when I use the remotes. When I use the wired controller, the door starts to close but immediately reverses. To close the door, I have to hold the wired button until the door is closed. THis doesn't work with the remotes.

Strange thing is, there has been a few periods, of three or four days, where the door was working fine. Once, it worked with no problems for 3 days, then stopped working. I looked at the sensor and the green light was completely out.

Same thing happened to me a couple years ago.It was the sensor wiring loose at the terminal board,check that.Could be the sensors also,call the company and see what they suggest. Did you check the adjustment on the sensors?Might be off enough to not get a solid signal.

I'm in the process of installing a door closer on my garage.
The instructions go to great lengths to say that the door must be balanced and travel freely.
They include instruction on how to test the balance and freedom of travel.
I would check the manual to check what the requirements for your opener may be. And look for the fault clearing section in the manual, and follow these instructions.
It would be a good idea to check all the wiring connections. Especially, splices that may have been made in the wires.

We got the opener back in 2003. It had operated perfectly up until now. I didn't make an splices with the wires and I don't see any way the wires could have gotten damaged.

The problem is definitely sensor related, since the green light on the sensor is either flickering or completely off. Do sensors go bad over time?

I sent a message to Chamberlain. I'll let you guys know what they say.

Did you check the wiring at the terminal board[on the opener]?The wire for the green sensor could of come loose. Yes,the sensor could of failed.

They are not aligned properly to receive a steady glow. The side jamb track may be loose or the bolts holding the units.
