I installed OME;
-Surface Unit Switch, [this handle the non-control issue of the Burner staying on high ]
-Surface Burner Receptacle [the Burner staying on high may have damage the Receptacle ]
-Control Knob [the knob had been badly damage over the years, so a new one was in order]
All of this took less than 45 minutes and there are great DIY video on APP site for help.
I bought a new Burner/Element a few months ago, so this make it all new and it feel that way.
All in total for what feel like a new stove-- under 100 bucks!
