When I recently changed the igniter on my stove, I noticed that there is a large blob of high temp silicone or RTV where the wires pass through the back near the feeder assembly. I was careful enough that I was able to keep that blob mostly intact but it did loosen up a bit. I got the impression from reading a few other threads on the forum that Harman now uses some type of grommet rather than the silicone to seal off the pass through. Can anyone confirm if that is the case and maybe provide a photo or part number if known?
