I just joined because I have a problem with my garage door opener.
Pretty simple: installed since years, it was working perfectly from the outside (even through the metallic garage door). Last week-end my neighbour installed the same model of garage opener (but newer!). Since then, none of my remotes (3) work from outside (of course I checked the batteries). It works inside the garage, or if the door is open, but as soon as the door is closed the range is too low. The garage of my neighbour is very close (shares a wall with mine).
So my first guess is interferences (I'll ask my neighbour to unplug his door opener for a while to check if my remotes work), it's just wierd Craftsman did not consider such a situation!! I think the only way to fix this problem would probably be to add the antenna extension kit (Sears part 41A3504)...

What do you think? Do you agree with interferences, does it make sense? Can 2 garage openers from the same brand work that close without interferences?
It's getting colder and colder, I don't want to get out of my car to open my garage !!! ;-)

Limited range of your remote controls could be related to radio frequency interference that comes from something in your home or in the surrounding environment. Certain electrical devices can radiate interference; this could be almost anything that is plugged into an electrical outlet.

Please keep in mind that the device can be brand new, or can be an item that has been in use for quite a while. Also, the item may continue to function properly as far as you are able to tell. The only problem with the item may be that it has started to broadcast the interference, with no other symptoms noted.

Some devices are more likely to generate interference than others. This includes TV cable, cable amplifiers, surge protectors, fluorescent lights, battery charging devices (power tools, golf carts, etc.), anything that utilizes a timer (sprinkler systems, lights, alarm systems, etc.), and a myriad of others. If the problem seems sporadic, we can safely assume that the device responsible for the interference is only being operated during these times. Again, please keep in mind that the age of the device does not determine if it is capable of broadcasting unwanted interference. Any electrical device can be the source of the problem.

So I tryed to extend the antenna from the middle of my garage to the wall (~13 feet), with the last foot going done (for polarization). Connection is ok, but no range improvment.

My 2 last ideas are:
* using a shielded wire for the antenna extension instead of a simple low voltage wire ;
* or, maybe the logic board of the opener is going bad. In that case, do you know how I get a new one?

Thank you.
