Large burner only sparks for other values to light and won't light by its own switch
On the largest burner, the ignitor will not spark when I turn it on. It will spark when the other burners are turned on. I replaced the ignitor without success. I think it has something to to with this particular values spark switch. Can you help?
Re: Large burner only sparks for other values to light...
Sounds correct, if it didnt spark at all and you had not replaced the igniter I would check that the wire from that igniter be followed to the other end to verify that it had not come unplugged at the other end.
On a new range I bought that igniter would not spark even though the others did and its wire was unplugged

The spark switch attached to the gas valve is bad, but usually you have to replace the complete switch string. Yes, you are right, all the switches are wired in parallel, and all the ignitors spark at the same time, so if you get 1 burner sparking, they will all spark, and now you can turn on the gas valve with the bad switch, and it will light too. (That's your cheapest and easiest solution!)
1) the switch that supplies power to the spark module when the burner is turned on is bad...its located on the shaft of the burner valve thier is one switch for each knob so counting the oven and the burners their is 5 (the oven is different from the surface burners) to check those switches what needs to be done is remove the knobs then the face panel so ya can get to the knobs.
No is where is gets a bit complcated if ya dont follow all procedures....the knob must turned on to check so gas will be flowing and ya must light the gas using a match or raw gas will eneter the kitchen...or if possible temporarly turn off gas supply to the unit.also POWER MUST BE DISCONNECTED and then with power off and the burner lit manually once turned on ya would need to check each switch to have continuity,if any of the switches does not have continuity when measured with a ohm meter that switch will be bad
2) the igniter is cracked so power is coming from spark module yet since its cracked power is jumping out before it gets the where it lights the burners.
Typically the burner come off by removing the burner caps and inside the burners are 2 screws that hold the burner base to the top..yes you could swap igniters on all burners they will be the same. If by swapping the igniters it still doesnt work the things that could be the problem are;
the spark module espically if the igniter that doesnt work on that burner suddendly work on a different burner
the spark switch on the gas valve for that burner..typically all burners spark when one it turned on but the only one that lights is one that has gas flow to it..so turning on a different burner first and leave it set to light setting by turning on the one that doesnt light it will light if that spark switch is the problem
of course a cracked igniter
a broken wire from the spark module to that igniter taht doesnt work..its not that uncommon that the insulation will sometimes wear off a wire off so the electric that should be going from the spark module to the igniter is instead being grounded by that wire touching the metal on the frame uninsulated
Good luck,i hope i have been able to help you fix your range, GENE
all ignitors spark at the same time no matter which burner is turned on. If you are having trouble with one burner not lighting try cleaning around the ignitor with a small screw driver so the spark has a good path to ground.
Hi, when any of the knobs is turned to the light position, all burners will spark. That being said, if one or more of the knobs is not switching the spark module, the problem is the switch mounted on the shaft of that burner valve. You need to replace the defective switch or you could turn on one of the good burners (to make the clicking occur) and then light the burner you really want.
You may have a bad burner switch. If you turn one of the other burner switches to make the spark modules spark look and see if the electrode is sparking at the bad burner. Most of the spark modules send a spark to all 4 burners when activated. If it sparks when another burner is activated open the valve and see if the burner will ignite. If so you probably have a bad burner switch.
All ignitors should fire regardless of which burner is turned on. See if the right front will light up if you turn on another burner or look for a spark. If not, the ignitor is probably fouled and needs a good cleaning. If the right front burner will spark or ignite when a different burner is turned on, it is the right front control switch - not an easy fix. When cleaning the cook top, if you remove the knobs, any liquid that gets into the switches will short them out. Found that out the hard way.
How old oof a unit is it? The burners switches when on will operate ignitors for all burners no matter which switch is "turned on". Usually when units get older these switches on the most "often used" burners will stick and stay "connected" then all ignitors will continue to spark this is also true if switches accidentally get wet with spillage or water till they dry out. No danger though because jsut because ignitor is sparking doesnt mean gas is being released, gas is only released when valves are turned on
All my ignitors spark when I turn one of them on. I'v been told it is normal. I had a problem before and the tech that replace the ignitor said the issues is with alignment. Try to rotate the burner a bit left or right and see if it fixes it.
