My garage door is half open. It makes a clicking sound when all openers are tried, no movement. The door is disconnected from the trolley.
It is a Sears 1/2 horsepower model 41A5O21-3C. The door is stuck half open. It makes a clicking sound with all openers, remote or wall. I unloaded the door from the chain, no change. The yellow light on the back of the opener is flashing.

I suspect the yellow led is flashing a number of times, then pausing, and doing it again. This is a code to give you an idea of what is wrong.
I am sending you an image with the flash codes. This should give you and idea of what is wrong with the opener. The codes give you instructions for trouble shooting the different problems.If you have more questions after receiving the flash codes, send another email and we will help you diagnose the problem.
