I have a GE smooth surface stove, model JBS55DM2WW.

It has a strange switch problem. When I turn on the front right large burner it does not come on, but if I turn on any of the other burners and then turn the front right one on, it comes on.

Seems odd to me (being an electrician).

Is this a bad switch, and if so is there no switch to switch protection against feed through such as this or is it built into the switch?

    Sounds like something's cross-wired. Is it under warranty? Is this a recent occurrence? – Daniel Griscom Aug 9 '16 at 23:51
  • Does the stove use spark igniters? If so, the problem is probably a faulty electric switch on the front right burner control knob. – A. I. Breveleri Aug 10 '16 at 1:46
  • @A.I.Breveleri -- this is an electric range, not a gas stove. – ThreePhaseEel Aug 11 '16 at 4:22
  • @ThreePhaseEel: You know, Morgan Freeman made reading seem so easy, but I never could quite get the hang of it. - It says right there "smooth surface stove" duh. – A. I. Breveleri Aug 11 '16 at 12:48

    Hi Daniel , The stove is 2 years old, I verified the wiring to be correct via the factory schematic. I decided to swap the front right switch with the rear left switch. The problem moved to the rear left burner. It's strange that the switch would fail to the point it becomes a safety problem. Very poor design by ge. I sent ge an email explaining the problem 6 days ago and they have not responded. I have a new switch order, should be here soon. – Tony Mitchell Aug 17 '16 at 4:24

You clearly have a wiring problem. It sounds like you have lost one phase to the burner that has the problem. When you turn on the second/support burner, that switch is back-feeding power to the problem burner switch.

Also inherent in these kind of problems, you may be getting the 240-volt to all the switches but somehow the wiring connections or wire leads have lost the ability to carry a load. Look for burned and or worn leads and connections.
