My AccessMaster Garage Door Opener Is Crazy



Question:
I've tried so many things to correct my problem with my garage door opener. I have an Access Master chain driven 1/2 hp. opener. Here are the symptoms: The opener will only move about 6 inches then stop on the way down. Sometimes it will go all the way up, other times only a few feet. The distance of travel up or down is intermittent. Generally though on the way down it will not go all the way down in one click of the button. I have to click it about 7-10 times to get it to go all the way down. Things I've tried: Cleaning the light sensors Realigning the light sensors (although I didn't have the proper tools) Adjusting the force adjustments Adjusting the distance limits Pulling the emergency latch and testing without the garage door load Reseting the opener Unplugging the opener Testing from the wall switch Testing from the vehicle switches Is there an easy way to check on sensor alignment? I thought about using dry ice, but I'm not sure if the light would show up or not in the "fog" I'm guessing that i have something failed in my electronics portion of the opener. I have not pulled that out to look at it, and it's mostly surface mount technology so I'm not sure if I could even tell by looking at it anyway.

Answer:
Typically, if the sensors are not aligned correctly, the door won't operate at all. Since you get some movement, they are probably working. But to be sure, you can move the transmitter and receiver right next to each other or completely bypass them if you know how to wire it that way.
