Rt.front burner goes to full hot no mater what setting

This is the correct way to wire the right front burner on Jenn-Air JEC8430ADS cooktop. Let's do the red wires first. The red wire that comes from #2 on the switch goes to the common connection for the element that should be labeled 2a. The other red wire goes to either of the "b", hot surface indicator switch contacts and the black to the other. Use 1b or 2b for these connections whichever reaches easiest. The yellow wire goes to the inside loop of the burner and the tan to the outside element.

abrasive cooker cleaner. and pad. should clean it off. give it a good scrub.

replace the burner RT/FRONT

You could have a shorted burner, if it is not then you may have gotten a bad part.

always unplug electricity before attempting to repair on any electrical appliance

The switch contacts are burnt and sticking. Very common problem. The model and
serial should be behind the bottom drawer on the (right side for GE). This switch runs
around 45 dollars. I do not recommend using a "universal" as they are just a pain to install and cut the shafts.

The right rear burner switch is bad.

the contact may be loose but most likely the burner needs to be replaced. the one you use the most usually goes first, and not getting hot enough is the common indicater of a shot burner

This would be a faulty switch. Hope this helps!
