G Electric Range - Infinite switch burning up repeatedly, burner staying on high no matter what the setting

I have an LG smooth-top Electric range, LDE4413ST, that keeps burning up infinite switches on the Right Front burner, which is a "dual element" burner. This burner also operates at high power only, this behavior seems to start when the switch burns up.

Here's what i've tried: - Tested continuity on the wiring harness (seems fine, could not find a short) - Tried a replacement cooktop heating element (it operated at high power all the time, because the switch was bad and I didn't know it yet) - Took out the replacement cooktop heating element and put the old one back in - Replaced the infinite switch since it was burned/scorched at the P1 terminal (replacing this worked for a few days, then stopped with scorch marks at the P1/Ls terminal. When this happens there is continuity between this terminal and 2/H2, which I understand is not supposed to happen) - Checking the cooktop heating element resistance on the original burner (was fine)

The range is an LG LDE4413ST. It is the right-front burner that is having this problem.

Everything else works on this range.

Any help you can provide would be greatly appreciated!
