I have tried troubleshooting tips, cleared the eyes and reset by unplugging the main unit. When replugged, there is a red dot in the white bar on the transmitter that attaches to the opener tabs 1, 2 and 3. When the red dot is on, I can push the white transmitter bar and the door will close. Hit it again and it opens. After it closes again, it will not reopen and the red dot is not lit. The remote does nothing at all. The remote red lite is shown when the remote button is pushed that confirms the battery is working I suppose. In taking the battery cover off I may have changed the dip switches but have recycled the entire unit several times since if that is the means to reset the remote to transmitter. I have cleaned the door safety eyes and confirmed the wires are connected. I have not seen any sign they are working and their red light does not blink. When I began to "fix" the "close using the remote" problem, the remote would open the door but not close it. Now the remote does nothing.
I am glad to provide volt/ohm meter readings given various situations, let me know what tests to perform. I think I am close but believe I am missing some critical troubleshooting understandings. I tried to shortcircuit the eyes and use the transmitter white bar but that did not work but may be its design. Would it help to know if each eye has an open or closed circuit? Is there any test I can perform using the remote and transmitter without it being attached to the opener?
Any and all suggestions will be appreciated. Let me know what tests to perform. thanks, tom
