Try this one: I have a Feb 2001 build date - model 9200 41A5021-5E circuit board. The door open on its own but I have to hold the electrical control (not the two remotes) down until it closes. I installed two tentative sensors along with contemporary wiring. The starter lightbulb blinks 10 times and the door will not close when I depress any of the three controls. The red sensor light blinks twice after pause; the green sensor oil lamp is constant, the amber light on the motor blinks once every 10 second. I called chamberlain customer service they suggested electric wiring with more or less two feet of line, hold sensors right next to respectively other...no changes! I jump the red with the white post and it works as if I pressed a control, comes up but not down! I switched electrics to one black/one white on both posts..no change. They suggested a brand new board - I'm thinking it has to be something else because the amber feathery flashes, the door opens on it's own but have to held down to close! Now the red light blinks 3 times
Answers: ok I'm lost on the red sensor street lamp. Chamberlain has impracticable red sensor lights on the eyes in a long time, I'm chitchat mid to early nineties. Your eyes should any be both green or one yellow or amber restrained one green. If it is the latter the amber eye should always be on, and the green should be solid when pointed directly at the amber eye. On the eyes beside two green lights one will be labeled transmitting the other recieving. Just like the other set the one streaked receiving should be lit when pointed at the other eye. Make sure you wired them up correctly. Make sure you hold the black wire contained by the black terminal or the one to the far left, and the white wires on the one discoloured white or the one right beside it to the right. If all to be precise ok, and it does not work when short wiring later you probably do have a discouraging board.
I agree with the fellow above. Red indicator lights are no longer within use so this makes it difficult to diagnose your trouble. It does nouns like a fruitless board the best I can tell from your discription. The amber lantern on the motor flashing peiodically is normal. If the orange/yellow indicator lantern on the photo sensor is blinking then it have to be a faulty board that isn't sending constant current to the sensors. The orange/yellow indicator neutral serves only as an indicator showing whether or not the sensors are getting power.
