All four top burners will not ignite, gas is present but no spark, faint clicking sound when turned to ignite. What needs to be replaced and how do I get to it?

Hello. The range you have has a spark ignitor module inside the top, beneath the cooktop. Also, there is a spark ignition harness that has the four switches(snapped onto each of the burner valves at the control panel) connected together(daisy chained) that goes to the module and the incoming 120v supply. HOWEVER, the bigger issue here is getting to the module, harness, and other parts beneath the cooktop. Gas ranges are notorious for having the mount screws seize in the burners. When removing them is attempted, the heads usually snap off causing burner replacement to be necessary(which is why I listed the part numbers for the burners and screws). The cost of this can be high. I suggest calling for service if you are at all hesitant about working on the range.

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.

The igniter switch(s) has most likely failed shorted. Fairly common with gas ranges with spark ignition.

Hi,
Here is a tip that I wrote that will help figure out why the burner spark keepson clicking...

Gas Range Repair Burners Keep on Clicking

Very likely the spark module. All four are supposed to click when one is turned on, however they are supposed to stop when the burner ignites. Replace the module and test. Good Luck, Appliance Specialists

Hi


Thanks for using FIxYa.The igniter doesn't stop clicking due to a short inside the igniter circuit or due to moisture present on the ignition switch.Turn off the gas supply immediately and also unplug it from the mains power. Now take a blower or your hair dryer and blow hot air over the igniter. Also check for the following troubleshooting steps---


1) The gap between the igniter and the burner base is too large. *Should be approximately the thickness of two dimes.

2) Soiled igniter or burner base.

The above can be tested by switching the suspected burner with a known operating burner.

3) Loose wiring connections at the igniter, the grounding strap, or spark module.

4) Broken or pinched igniter wire between the burner and module.

Both of the above are physical inspections under the main top.

5) The module may have a week coil, which is not providing sufficient voltage to ignite the gas.

Even after performing these steps the igniter doesn't stop clicking then you need to replace the spark module.

Please do rate the solution and revert for further assistance.


Thanks

sounds like a wire is'nt making good contact, check the leads that run up to the ignitors... the ignition module may need to be replaced

I unplugged the wires from each end and re-attached the wires. Stove working great, no more clicking.

I have a Thermador Gas Range PG364GDBS - Oven, 4 burners, and center griddle. All are gas. The four burners and gas oven work fine. The griddle just stopped working, no spark. Turning on the griddle control, the gas valve opens(hear it), gas flows (smell it), but the ignitor will not spark (no loud or faint spark that I can hear). I got a replacement ignition device (mount at the burner) thinking it might be the problem, but still no spark. I checked the AC voltage at the terminal and measured 39 VAC between the terminal and ground. Not sure if that is the correct voltage. Any insights or advice would be great.

Had The same problem. I removed the top of the control panel to find out that one of the ignitor switches had turned when I replaced the four large plasic nuts on the control panel. Make sure the switches (block) are aligned, and kept aligned, when re-installing the top of the control panel. Startwreck.
