2 burners wont ignite

First it could be leaking from the control knob when it is on . There could be a leak at the base off the burner letting out gas or on the burner line . You need to get back on to your installer or where you purchased the cook top . This basic gas fitting leak detection .

You could have a clog in your gas line. Have the gas company come out to check the pressure.

Hi,

Gas Range Repair Burners Keep on Clicking

Hi and welcome to FixYa. I am Kelly. On your cook-top the gas igniters are cycled on and off by a ceramic and copper switch on the front of each of the gas valves. Some of them are in wired Series ...i.e any burner on will cycle all igniters on the cook top and some of them are in Parallel where individual burners are controlled by each gas burner control knob. Inside these tiny ceramic switches there is a flat thin strip of copper that as the gas valve is rotated a cam of the switch actuates pushes the copper strip against the fixed contact. Those little strips over time either break or get bent and stay against the fixed contact. Hence you have and igniter on when the burner control is off. The only fix is to find out which little ceramic switch on the front of the gas valve is stuck. You do it with an Ohm meter POWER off. They all should read open with the burner controls off. The one that reads continuity across the 2 wires is the bad switch.

Thanks for Choosing FixYa.

This sounds like a burner switch.There is one under every knob there are two wires going into them. i think the part number is 7403P367-60.

Take the burners out, then take a needle and stick in the small hole where the gas comes thru.

As it relates to 5 burner gas cooktop Model Number JGP 963SEJ1SS
First - Ignite the flame then reduce the flame to between low and medium.  If the igniter continues to click, you most likely have a contact switch issue related to the problem burner.  
Unplug the cook top and turn off the gas.  After the gas is turned off, disconnect the gas line.  
Remove the cook top.  

Unscrew and Remove ALL of the burner bases by lifting them up.  The ceramic igniters may be difficult to remove but they will come loose if worked out slowly.  
Pull of the wire connected to the igniter. 
Remove to cook top top plate from the base, exposing the internal gas valves and wiring.
All of the burners are wired in parallel.   Lift off and unsnap the casing of the problem igniter switch.  The repair may require something as simple as, 1- cleaning the contact strips, or 2- slightly bending the non stationary contact strip to keep it from coming in contact with the stationary contact when in the off position, or 3- replacing the switch. 
Unless you comfortable and understand how electric systems and switches work, this is a job for a qualified repair person. 

Either the potentiors or the simmer control.

Check to make sure your burner caps are aligned. I had this problem, and it turned out one of my burner caps was slightly askew. Putting it level fixed the problem.
