I have a Overhead Door model 45A that has and old touch n go remote. There isn't a learn button or dip switches in the unit or the remote. It's a 390-LCC frequency. The original remote only works occasionally so I bought the recommended replacement with the 9 dip switches and we can't figure out the code to set it to the opener.. I have called the OD distributor and he tells me I have the right remote and it will work.. but unfortunantly it won't without knowing the code. Yes we have taken the cover off the opener and looked everywhere even tried to set the remote to the wire configuration in the 12 socket plug that goes into the circuit board. Any answers? Thanks!
