[RFI] Garage Door RFI

[Jeff]

I've had the same problem over the years with the last 2 years occurring only
during the months of January & February.

It's always slow to deteriorate, over a few weeks, from a optimal distance of
200' ending with having to be right at the door pressing multiple times.

Changed all batteries, reset, & reprogrammed to no avail.

This year I systematically threw breaker by breaker & never did isolate it.
Bought a new main board for the opener with no joy.   Problem just went
away in March.  I have a heated entry floor thinking maybe it was seasonal,
but that was not it.  I've heard that routers can interfere.  Was thinking it was
the neighbor's house which is a rental, but different tenants last 2 years.

Very frustrating ..... but at least my oven never came on.
