Chamberlain/liftmaster garage door remotes don't work anymore


garage door remotes don't work unless I'm abot 10 to 15 feet away. Up till about a month ago (for the last 5 years) they worked from about 200 feet away. I have changed the reveiver board and tried a new remote with the same results. Has anybody experienced this and found a solution. Has anybody had any interference problems with invisable dog fences? A neihbor put a fence in but that's even about 200 feet away. Thanks for any advice.

I would have guessed battery but looks like you've tested for that by getting a new remote.
My LM's get balky when the remote battery is old..... a new one brings operation back to normal but I only get about 50 ft, nowhere near your original 200 ft.
When did the dog fence go in?

Bob, Thanks for your reply. The dog fence went in about a month before I started noticing problem. I went out after I posted this message and reprogrammed remotes. They are now working at about 30 feet. I guess I'll see if they work tomorrow.
