Your video was vary helpful, letting me know what to expect. I fixed 2 burners with vary little problem. I have done electrical work before. Never used the shrink stuff before.
Had a little problem with the shrink stuff because I used a propane unit that was a little hot but I got it done. Took about 2 hours because I took my time and had interruptions.
I used a wire skinner, diagonal cutter, screw driver, propane heater.
It works fine. I have been popping corn and making oat meal with no problems.
I wished I had ordered some new pans that go under the 4 burners.
