When you want to buy a new one that’s when! I have hated my garage door opener for about a year. It only has one controller, no keypad entry, and the rail is bent so the door does not go down smooth. Well recently the door has stopped working; sweet time for a new one. However, before I can go and drop the cash for a new one I feel like I need to give due diligence to fix it. Sure enough I am able to find a short in one of the sensor wires, and poof visions of a good garage door opener go up in flames. I replace the wires, and everything worked great, dang it! Merry Christmas everyone.
