The left front dual burner won't turn off. It quit with the small burner on. I need to turn off at breaker. The range has ESEC controls. Do I replace the RF element control, the UIB and slave or what?

It is probably a stuck relay on the power control board. Unplug or turn power off to the range and remove the back panel to gain access to the power control board. Tap on each of the relays using the back side of a screwdriver handle. After you have done that put the back panel back on and turn on the power. See if that makes the burner stop staying on, if it does then I would start by replacing the power control board. Let us know what you find.

This is the power control board for your model range:

I tried, but the burner stays on.
