Hello,
The front burner on the right hand side of this unit is intermittent. It is a dual sized surface (you can operate as a small burner or large). Sometimes you turn it on and walk away, but it never heats up. Once you cycle the switch it will usually work right away. The problem is getting progressively worse over time. The rest of the burners have never had a problem.

Is this as simple as replacing the switch behind the knob? Or could it be something else?

If it is the switch, what is the part number that I should use? There were 2 different switches when I checked.

Thank you for your input.
