[RFI] Lennox furnace: when it heats it roars (RFI)

[Lee Sawkins]

I too have a Lennox furnace that cause a lot of RFI.  It is a G71MPP.
I have not fixed mine yet but I have corresponded with VA5LF.  He posted a fix for this furnace on FlickR

In a private email to me he stated he also had to put beads on his thermostat leads.
He used DX Engineering snap on ferrites.  These are type 31.
