On the Jenn-Air JES9800AAB, if the dual burner only runs on HIGH, the original infinite switch was very likely bad. But the replacement dual-element switch may have a different terminal layout, so you should not transfer the wires based on physical position.

The replacement switch terminals need to be matched by their terminal markings. Typically you’ll see markings such as L1, L2, H1, H2, P, plus an additional terminal for the inner/outer element on the dual switch.

The safest way to handle it is:

  1. Turn the breaker OFF.
  2. Look closely at the old switch and write down each terminal marking and the wire color connected to it.
  3. Look at the markings molded or stamped beside the terminals on the new switch.
  4. Transfer the wires according to the terminal designation, not where the terminal sits on the switch.
  5. Don’t guess on the extra dual-element terminal. A wrong connection can make the burner stay on high or energize the wrong portion of the element.

If you can send me a clear picture of the back of the old switch and the back of the new switch, with the terminal markings and wires visible, I can help you map old terminal → new terminal.
