Kgra 806 top oven burner only works on broil, not convect, I already replaced the spark electrode

I recently has the same issue, on my stove the gas valve worked both burners on top and in oven. and yes with a bad spark electrode what will happen is the bad electrode will send an error message to the valve and the valve will cut off all power to the oven. element which has the bad electrode. I t may not be a bad electrode but like my case a bad control board after checking my board I found the oven element capacitor was burned out. instead of replacing the whole board which can be expensive I bought a capacitor very difficult to find, and soddered it into the board ,

Most Frequent Causes for Oven won't turn on. ... The igniter is the most commonly defective part for a gas oven that won't turn on. ... For bake & broil burner ignition anoven burner spark electrode is used to ignite the gas.

There is a service flash, W10622771, for gas ranges of your model number--the bake burner ignitor is not lighting the gas--it's a direct spark ignition type. The ignitor is sparking but no ignition. Possible causes are (1) Wiring harness might be pinched between the bake/broil ignitors and the DSI board. (2) DSI mounting bracket may be contacting a solder joint on the back of the board. (3) Positioning of the ignitor and gas burner ignitor ports may be out of adjustment. (4) Ignitor electrode deterioration
Facing the range, the DSI board is behind the control panel on the left side, mounted in the bracket.You'll have to remove the back cover to expose the boards. BE SURE TO UNPLUG THE RANGE BEFORE DOING THIS. I can provide diagnostic mode if you want to proceed further.

Check your lower burner, it could be shorted out. very common thing to have happen

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

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

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

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.

For broil burner ignition an oven broiler burner spark electrode is used to ignite the gas. The electrode is a device that sits right next to the broil burner. It functions like a spark plug. As power is applied to it a spark jumps from the spark electrode tip to the to the electrode shield, igniting the gas. If the electrode is broken or worn out the spark may not occur or be intermittent. Visually inspect the electrode assembly for cracks in the porcelain housing or damage to the electrode tip itself. Be aware that a proper ground and the correct polarity of the incoming voltage to the range is necessary for the electrode control to sense the presence of a flame once the burner is ignited.
there is also a spark control module but I don't think that's it usually no spark when bad.

hope this helps a little

older ovens have pilots but the newer machines are electronic ignition,there are ignitors in the oven and electrodes or ignitors on the top burners,when you turn the knob for the burner you should hear a clicking sound and see a spark around the burner,that's what lites the burner,the gas comes in and the spark ignites it,i don't know much about your machine but it can't be any different from other stoves.if none are sparking there should be a spark module in there or they could have separate modules,if you send the full model number i can look it up for you

Hi,

This is a common issue and cannot be troubleshooted. The only way to fix this is to replace the temperature probe. The error will disappear and the range would start working fine.

Please accept the solution if it's helpful. Do get back to us for any further query.

Thanks for contacting fixya.com

You will need a new igniter module. The igniter module is told to spark by the control panel. There is also a flame detection for electronic start and that could be bad too.

before you replace the control panel, take a quick look inside the oven at the ceramic spark starter.. when you (tyr to) turn your oven on you should hear a bunch of little snap sounds.. sparks trying to light the burners inside the oven..

if you try to use the element (broil) without the gas - you'll get a better bearing on whether or not the gas element(s) are lighting or not inside the oven..

hope that helps..
