It depends on what is causing it. My problem is caused by a Ham Radio
antenna in the garage attic, directly above the wires to the garage door.
I added some of Radio Shack's 273-0105 "Snap Together Ferrite Choke
Cores" to the power and control wires going into the main unit. It
helped a lot, but occasionally it will still open when I transmit. I
need to add more chokes!
