My GDO doesn't work right
Help! I recently replaced the main drive gear and worm gear on my Sears 1/2 hp garage door opener, model 139.53535SRT1. Now, after I reconnected everything the only travels about 8 to 12 inches each way. I also noted that the LED bulb next to the code button flashes five times, then pauses. It continues this cycle. Can anyone tel me what the five flashes stand for?
