Hi all,
I have a Chamberlain 4600 1/2hp Screwdrive opener - 1997. It stopped working one day, so being the DIYer that I am, I pulled the board out of it and noticed one of the resistors on the logic board looks fried. I'm unable to tell the band colors on it so I hit the net trying to find it. I can find replacement boards, but no schematics. Of course the replacement board pics are too small to see anything... I emailed Chamberlain, but I'm not expecting to get the info I want. I was hoping someone on here might have one of these and could peek at their unit. On the circuit board there's a resistor marked R29. It's next to a capacitor on the lower left of the board.
I know it could be a bigger issue that it fried, but why not spend the buck and fix it myself if that's all it is.
Thanks for the time.
