Hi, my name is Peter.
Do you have the brand and model # XXXXX that I may do research and help you.
Thank you for the information.
Sorry, but I did not get the notice that you had sent the model #. When you turn on one of the burners that do light if you see a spark from the igniter on the burners that do not light (all 4 should spark when you turn on any burner) then you have defective igniter switch's (that are mounted on each valve). If you do not see a spark on all 4 burners then remove the burners that do not light (twist 1/8 turn ccw and lift) and check the wires to the igniter on each burner. If the wires are good then you have a defective spark module.
You may send additional questions directly to me.
