I had severe Garage Door Opener RFI. I filtered the AC input...no
effect. When I filtered the "open push butten" lead and the photo cell
leads (the long ones to the bottom of the door) at the opener, no more
problem! I used brute-force filters right at the opener. A Radio Shack
100uH choke in series with each lead and .01uF caps across each pair on
both sides of the chokes.
