If you can't get the opener to program using your known good remote then your logic board is bad.

Ok, me being a novice to this sort of stuff - how do I replace / fix the logic board?

Thanks in advance for your help!

You are not going to be able to repair the logic board. It is replace only. It is the end of your opener where all those white wire go. If you had a new one in your hands you would know what was involved. They cost around $80.00.

Ok thanks for the help, I guess I'll give that a shot.

I too have been having programming problems. I am trying to program the control built into my car. I tried using the learn button. Didn't work. My note about the Premium Control Console says it "Can be used to program the opener to accept additional remotes." It doesn't say how. Does anyone know? Thanks, Eddie

if it is a fixed-code model which uses dip switches to set the address pins of encoder and decoder ic, maybe you should check out the remote control dip switch calculator at solidremote, it will save you a lot of calculations.
