For burners, the sparks should fire vertically upwards. If not they wont light gas. If the other three are not sparking, and this problem started at the same time. replace the spark module. If the sparks failed over time, replace the spark switches which sits on the shafts of each burner.

If no gas to oven or burners, your problem is the gas supply...to the gas valve or leaving the gas valve.
This repair would be for a trained person.

SOURCE: burners don't receive gas though oven/broiler does

tommi, this model has a cooktop lock-out solenoid feature. Try pressing and holding the top light keypad for 5 seconds and see if the top comes back to life. If not, check your owners manual, it may be a different key. The lock-out solenoid is in the back behind the outer panel. The cooktop lockout valve has been redesigned from a AC to DC voltage because of complaints of chattering. The new part number is 8184768. Lets hope you don't need it and just have the top locked out.

SOURCE: changed from natural gas to propane when new oven flames up the side top burners ok

Just bought a Kenmore and did this conversion myself. You do not change the oven nozzle (jets) but have to wrench it down with a 1/2" wrench as per instructions. After I did this the falme was high as you described. I wrenched it down further and adjusted the air shuttle and it was fine. The brioler is done the same. The wrench adjustment is tight so be aware.

SOURCE: electric start gas range

You either have a short in your electronic ignition or the ignition board is defective. Check the wiring to the ignition board for shorts. also check and make sure you ignitors are well grounded.

SOURCE: burner flame height adjustment

All ignitors will always arc whenever one of them does.

I haven't worked with propane systems much, but it seems you may need the propane pressure regulator adjusted.

If the problem is only with the power burner, I would ensure that particular orifice was actually changed. The hole in a propane orifice is smaller than for natural gas.

Why want middle burner light automatically but will light with a lighter


That unit is suppose to have electronic quartz igniters. Apparently there's a problem but it doesn't automatically mean the igniter needs to be replaced. If you see a spark from the igniter then it's fine. If you see a spark but no flame then the ignition process is out of synchronization. In other words, the gas hasn't concentrated near the spark enough to ignite. This may be a matter of low gas pressure or the extra length the gas needs to flow to reach the center burner is impeding ignition. Simple fix is turn the knob just enough to start the gas for 2 seconds then continue the turn to click the igniter. or simply use a match. You may also see if there are any adjustments on the gas manifold that will enhance bringing more gas to the center burner quicker. Some unit have one click & that's it, others click the igniter continuously until you release turning the knob. Good luck. you'll figure it out.

Range: Gas burner won't spark or ignite A surface burner igniter switch and a spark module activate the spark electrode when a burner is turned to the "Lite" position on a gas range's cooktop. If the surface burner switch, spark module or wiring in that circuit fails, the spark electrode won't work, and as a result the gas burner won't light. If those components work but the electrode won't spark, the problem could be that the spark electrode is coated with spilled food of is bent or broken. In addition, the electrode won't spark or ignite the burner properly if the ceramic insulation sleeve below the tip of the electrode is cracked or broken. If the gas burner isn't lighting, these repairs may help.

Replace the spark igniter electrode

1396454293470.jpg The spark igniter electrode-also called the surface burner igniter-is an insulated electrode that provides an ignition spark to light a surface gas burner. It sparks and makes a ticking sound when the burner switch is turned to the Lite position. Replace the spark ignition electrode if it fails to spark or if the ceramic insulation sleeve is cracked or chipped. How to Replace a Spark Igniter Electrode in a Gas Range Find This Part

Replace the surface spark module

1377098014986.jpg The surface spark module is in the ignition circuit for the gas surface burners. When a surface burner control knob is turned to the "Lite" position, it provides voltage to the spark electrodes on the gas surface burners. If the surface spark module fails to provide the electrodes with voltage, then it should be replaced. Find This Part

Replace the spark igniter switch

1396454315355.jpg The igniter switch is an electrical switch on the stem of the gas surface burner control valve. This switch completes a circuit to the surface burner spark module, causing the burner igniters to spark when the burner switch is turned to the Lite position. Replace the burner igniter switch if the burners don't spark when you turn the burner control knob to the Lite position or if igniters spark constantly even when the burner knobs are in the Off position.

I have a Viking vgic365-4G gas range. I recently replaced the spark module, the ignitors for the oven and the griddle, and the spark ignitors for the burners. The problem I am having is only one of the...


Hello,

their is one of two things causing that,

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.

Dead burner on kitchenaid gas cooktop?


it is strange that you have no gas and no spark! if you held a match to the burner and turned the burner valve on it would lite di spite a failed ignitor,but for it not to lite, the burner valve[its what the knob attaches too] would have to be blocked[thats rare]or ........i got it .....the knob is broken.thats the only thing the burner valve and the spark ignitor have in common.try a knob from another burner................again.you have spark,because others are working.spark on troubled burner would work if valve blocked at orifice outlet,and if spark failed you would still get gas they work independent of each other,[but in unison].thats why im thinking knob.its the item that works both .when you turn the knob it opens the gas valve and as the gas valve rotates by turning the knob it activates or turns the spark switch so it closes the curcit allowing the electricty to the spark moduel.hey i hope that helps a little. God bless ,tom

Electric spark for gas range burner is non stop


Turning any knob starts the spark via a switch behind each which should disengage when the (any) knob is turn further.
One of your switches is stuck.

I think you should be able to remove the range-top for access and find the offending switch.
It is probably gummy from a spill and is no longer in solid contact with the cam that operates it.

A solvent/lubricant such as WD-40 sprayed on the plunger of the switch once you can see it and operating the knob back and forth should free it up.

It might be wise to turn off the gas supply while tinkering with the range - blow your house away and the range won't matter. :-(
