Replaced logic board
Posted by Unknown on 4th Sep 2014
I ordered part number 97798 to replace the original logic board in the garage door opener (part number 78914) which was installed when the house was build in 2009. The original board was fried during a non-electrical storm power surge. The two circuit boards and one ribbon cable that came with the set installed in minutes and work perfectly with the opener. The new board also included a set of revised programming instructions.
