Re: Garage door opener receiver problem
said by KA0OUV:The remote keypad is wireless and is on the door frame of the garage door on the outside. It worked earlier yesterday afternoon, but seems to now to also not be working.
Does the keypad still work? Is it wireless? Do the OEM remotes still work?
As for CFLs, I extinguished one nearby CFL and the tubular fluorescent lights in the garage as part of my diagnostics with no effect. The door itself has a rugged-duty incandescent bulb in it.
No close by military installations. Well, Dobbins AFB is a couple of miles away. But again, one door works, not the other.
I'm going to get started today. I work in a home office so can mess with it some during down time to try the antenna re-route and relearn remotes. But I'm just about convinced that its the logic board. Will report back later on results.

My parents' Genie receiver board died last year... more expensive to replace the board than to buy this little guy...
It is marketed to take old dip-switch openers and upgrade them to rolling code but works great as a replacement. just a thought if none of the troubleshooting works

I think I may have solved the problem
I think I may have just solved the problem. And the Pogo comic seems to be applicable.
I first tried relocating the antenna. I stretched it sideways and was able to secure it to the nearest joist so that it was 90 degrees from the opener and parallel to the Earth. No change in symptoms.
I was standing there scratching my head for my next action when it hit me. I am finishing up a new computer build. Needing a place to work with a big table, I was using the dining room with its large table surface for that build work. I had temporarily stretched an Ethernet cable across from my office through the living room to the dining room for the new system and had been using it for a few days. Life was good.
We had guests over Saturday evening. In anticipation, I removed the Ethernet cable so nobody would trip over it. And then I enabled the motherboard's onboard WiFi connection so I would continue to have network connection. The chassis is sitting on the floor in the dining room, almost directly over the garage door opener.
I ran upstairs and powered down the system. Ran back downstairs and tried the opener again. Bingo. Car button works. Wireless keypad works. Ran back up stairs, rebooted server and assured WiFi was connected. Back downstairs. Symptoms present again. Shutdown the server again. Things work again.
I'll keep an eye on it, but the moral of the story is that the WiFi client sitting on the floor immediately atop the opener separated by 3/4" hardwood floor and subflooring seems to be the culprit at the moment. The timing of my first experiencing the failure seems to line up, too.
If anybody thinks the WiFi specs are relevant, the motherboard for my new system is an Asus P8Z77-V PRO and the on-board WiFi contains an Atheros chipset. I determined that the manufacturer of the WiFi unit that Asus provides with this motherboard is manufactured by Azurewave based upon looking up the MAC address.

Odd. Sounds like the PC wifi radio must be bad.
You never know, the diagnosis could be wrong, too. That's why I want to watch it for a while to verify it doesn't get flaky again. But so far the correlation seems to hold.

Could be a poor receiver design on the opener, with lousy out-of-band rejection. Or the frequency used could be a subharmonic of the WiFi frequency. It could even be a result of mixer products (spurs).
