Door won't go down using control
Make sure to clean off the lens so there's nothing blocking signal and make sure that theres no obstructions in the way of the photo cells before and during cycle. make sure that you have power going to them by having the Amber or red light displayed at all times and make sure that the green light is present for alignment. If it works for a couple of cycles and then goes back to being non active, make sure that the tracks or the surface that sensors are mounted to are not moving as door is in operation therefore they will move out of alignment during or after a cycle and will not allowed to operate! Make sure that none of the wires going to the cells are punctured through by any Staples! sometimes it could happen and when you move the cell around it could relocate from the staple and go back to norm, then after cycle it could short out from vibration which will send wire back to hitting stable! If none of these are helpful and you want a quick fix go down to your local home improvement store and buy a set of photo cell/safety cells and wire them up as diagram displays which is very simple and easy.

Wayne Dalton DoorMaster Model BDOr 2000 door will close but then goes back up immediately. How do I adjust it. Nothing is blocking the closure?
The Wayne Dalton Doormaster design is a mess. I've had two of them in my house for 10 years, with numerous repeat problems.
What you are experiencing is a need to recalibrate the door, but the underlying cause is that a linear potentiometer becomes non-linear, and the calibration drifts. Once this starts happening, it will continue to be a problem until you buy a new potentiometer, or clean the one you have. If you are handy, it isn't too hard to do.
Two other Doormaster problems are when the DC electric motor carbon brushes wear sand clog up the commutator, causing the motor not to run. Another problem can be corrosion on the back of the circuit board that causes erratic operation, but can be fixed by scraping the corrosion off the board.
If anyone still is having any of these problems, post here and I'll do a detailed writeup on these fixes.
