My AccessMaster Garage Door Opener is crazy!
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. Thanks, Michael |

Thanks, Michael 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. |

I'll try bypassing them or moving them right next to each other. I'll post the results. Thanks again. Michael |

Unless there's something breaking the beam intermittently, it's highly unlikely from the described symptoms they're the problem. Sounds more like intermittent electrical contact somewhere to me... I'd be looking at all connections, limit switches, motor connections, etc., etc., ... How does it operate if disconnect the door and simply actuate the closer mechanism? If it does the same, it's electrical/controls. If it operates normally, it's mechanical. -- |

I think I'm going to call Chamberlain tomorrow when I'm standing in front of the opener. Thanks dpb! |

Chain too tight? There should be about 1/2" sag in the chain w/ the
door disconnect from the opener. T-Rail dry? The operators come w/ a small tube of light grease that supposed to be put on the rail, but many people never use it.

ps.com... Chain too tight? There should be about 1/2" sag in the chain w/ the door disconnect from the opener. T-Rail dry? The operators come w/ a small tube of light grease that supposed to be put on the rail, but many people never use it. I'm having similar problems. No chain - it's got a worm drive. Same possible solution? It's spotless-clean somehow, which is odd since the rest of the garage is pretty dusty. I've got some spray lithium lubricant that works well everywhere else I've used it. Is this OK to use on the worm drive? |

I think I'm going to call Chamberlain tomorrow when I'm standing in front of the opener. Thanks dpb! Well after replacing the RPM sensor and the garage door still having problems, I called Chamberlain again and went through the troubleshooting process again. The second go around spurned new light about the problem. The agent that I spoke with said it was a problem on the logic board...an electronics problem. I ordered a new logic board. I received the board and replaced it. I haven't had any problems since. My warranty was expired so my total expense was around $100 dollars to fix it. Thanks for all the assistance! |
