Front 2 burners will not light - has electronic ignition and back 2 work fine. Front 2 spark intermittently, but seldom light. I've swapped burners from back to front and still front one's won't light. Am I looking at replacing the 2 spark ignition switches? The spark control module should be fine if the back ones work and front ones don't even after switching them out. Thanks for any help. Actual Model nr is FCG20510w, not the one I had to select below.
Re: JennAire Gas Range - 2 of 4 burners don't light
I had same problem and believe it or not it was caused by a Blue Rhino Propane tank. It was a new exchange tank and because of their "safety" features it would not release a sufficient amount of propane to heat with. Switched tanks and all burners fired up. Have found others on the web with same problem and solution.

If you don't smell gas, then it is probably electronic ignition and not a pilot light.
But if your oven and none of the range burners light, are you sure you are getting gas to the unit or from the range valve to the burners and oven? Can you light the burners with a match? If you can you can rule out the valve and incoming gas line, and concentrate on the ignitors.
there is probably some residue keeping it from sparking. look at 1 of the other burners and take mental note from where the spark is coming from. then spray just a little oven cleaner on and around the one not working. naturally take the metal grid off first.. let set for about 15 min. then wipe away the residue gently as not to damage the igniter electrode.. also there is a possibility the wire leading to the igniter fell off causing this problem.. do the explained first. good luck...
My GE gas range is really sensitive about the gap between the igniter electrode and the metal disc that covers the burner. If the metal disc is slightly off-center, no spark will occur. Check to make sure that the gap between the igniter and the nearest metal is about the same as the back burner.
some models have one gas pilot for 2 burner front and rear and there is a small pipe that goes front the burner to to the pilot, the burner has small holes facing the pipe the goes to the pilot that's where you take a paper clip or a safety pin and clear or clean the holes, the same thing on the electronic ignition, but some electronic ignition they have a spark right nest to the burner and by looking at the other burner that are working you can see where it's sparking, and clean in between the burner and the spark.
Your problem is not the igniter itself, but the burner switch that controls the igniter. All the igniters get their power from one spark module that is mounted somewhere in back of the oven. That's why you are able to get all the igniters to spark with only one burner control turned on. This is normal. That is also why you are able to light the burner in question buy turning on another burner. The spark is being provided by a switch that is working. To answer your question: the igniter is removable, but I don't think it's necessary. Cleaning them generally doesn't make them work better. I would check the wiring from the spark module to the burner switch and/or replace the switch. I hope this helps.
Most problems with gas ranges have to do with the flame--either it isn't quite right or it's nonexistent.
Most new gas ranges have "electronic ignition," a spark igniter that starts the flame as gas flows through the burners. If, when you turn on a burner, it fails to spark but you hear sparking at other burners, the igniter or the burner switch probably needs replacement by an appliance repairperson.
If your range has a pilot light, be sure the pilot light is lit.
