Bought two new burners and installed them. The problem with one burner was that the terminals (electrical contacts) had been redesigned slightly, as the range itself is probably at least 10 years old (Maytag Model MES5875BAB). Specifically, the terminals protruded about 1/2 to 3/4 inches farther than on the original burner. It was not easy to see, but that difference put the terminals in direct electrical contact with the grounded heat shield, and that short caused the controlling switch to burn out. I bought a new switch and modified the heat shield in such a way that the burner terminals would no longer touch the shield. I also did a little sheet metal work to replace the part of the heat shield I had to remove but to still provide the necessary shielding. There was room enough between the shield and the heat-protected printed circuit boards to allow me to do that. The other larger burner presented no problem during replacement.
