I have two cars with Homelink. Occasionally, the doors will not open when the button is pressed. Neither door will open and it occurs with both cars. The remotes that came with the door opener won't work either. Only the wired button works and then everything is back to normal for a few days or weeks. I can open either door with the wired button and that resets everything. Suggestions on what's going on?

That would be Dusty.

I think you have an automatic rotating passcode in the opener system. I think it is reset each time you use the physical button to close the door. At that time a new code is sent to each opener and the door receiver and everything is in sync.

I suspect something is flipping the code in you door receiver so none of the remotes work until they are all reset. Could be something electrical causing a radio interference, or perhaps a power spike. Do you have a SS Pro? They send out radio interference as some guys were reporting.

A simplified illustration upon reset the door and the remotes are all set to
0001 on the next open they might all be set of 0002, next time 0003 next time 0004 and so forth. If the receiver get out of step it might be expecting 0003 but the remotes are sending 0002. When you push the physical door open button the system resets remotes and receiver to 0001 again.

My example is way simple as most codes are 8 digits and no one knows the specific reset code that is sent when the button is pushed.

I did have a problem with my garage door remotes and the solution was nothing more than alignment of the beam.

I did a lot of other things while attempting to resolve that problem but it all turned out to be just a real good lesson (for me) on garage door openers.

Good luck.

If it were the alignment beam, would the wired button not work also?

No. The manual control works without the beam being completed.

One door has a rotating code opener (installed last year); the other has a fixed code. Neither door opens with Homelink or the remotes. Once one door is opened with the wired button everything works. It can't be misalignment of the sensors otherwise only one door would be affected.

Weird!

There is absolutely nothing you can do. Because you live at the exact mid point of a line that stretches between the center of the Bermuda Triangle and the last reported sighting of Sasquatch in western Washington, your screwed.

At least he is further from big foot than thee!:D
