I have gone through this. I disconnected the remote open switch at the
opener. The problem went away so toroids at the opener end of this
cable worked fine. With the newer openers, the cord to the safety
switch/light may also bring in the RF. Anything connected can bring it
in. I also use toroids on the A/C line because it is a GFCI and was
popping off with RF.
