My burner will not spark. None of the knobs will spark when I turn it on. I can hear and smell the gas, but there is no spark. So I have a two part question. What can be the problem? After removing the grates and the caps, how can I remove the top?

Re: No spark, I want to open to fix it.
The spark module may have failed. It is probably located under the top. To remove top, the mounting screws for each burner assembly will have to be removed. Each burner is secured to the top with 2 to 3 screws. It will be necessary to remove all screws on each burner in order to remove the top. USE CAUTION!. Do not force the screws if they seem tight. These screws will often corrode. Forcing them out could break them. The best method, if tight, is to move them back and forth (tighten a little,loosen a little,tighten a little,loosen a little etc.) until the corrosion breaks free. Once the burners are removed, there may be two spring clips holding the front to the cabinet. Is so, insert a putty knife and push until the top comes free.

Bill, two things possibly going on here that are common with an aging grill. First you need to turn off the fuel tank and set it aside. you mention that a clicking can be heard when pushing the igniter button which usually indicates good battery but if you have never changed it you may want to just as a good measure. Unscrew the bottom and you should find AA or AAA battery behind it. Now with battery good and the igniter generating a fast load clicking sound you want to get down and follow the wire that runs from the the back side of the igniter push button down inside and usually under the burner tubes ending out at one end of each burner. What happens when you press the igniter switch is, an electrical current is sent down the wire and when it reaches the end the current jumps to the closest metal it can find creating a spark.so you need to insure that the end of the wire is close to where the flame is generated but not so close that that you cant see a spark. Make sure the end of the wire is bare and clean as is the area on the burner where it arcs Now do this to all for burners. Turn all the knobs on the grill off and connect the tank. Make sure the lid is open now, and slowly open the valve on the tank. I say slowly like a ten count from close to full open. what can happen if you crank the tank valve open too quickly or with the grills valves open a vapor-lock effect can be created greatly reducing the flow of fuel from the tank. Iv'e seen many of the uninformed return 1/2 full tanks due to this problem. If you notice week flame or no flame but smell gas ALWAYS SHUT OFF VALVE ON TANK IMMEDIATELY KEEP LID OPEN AND LET THE AREA VENT BEFORE TRYING AGAIN lest you be the one being barbecued. Good Luck
Hello, You may have turned the gas tank valve on too fast. Turn it back off, disconnect it and reconnect it. Then very slowly turn the valve back on. Light one burner at a time and turn to low before lighting the next. If you are hearing and smelling gas with the tank on but all grill knobs off, don't use the grill. You may have a leaking grill valve, regulator or hose. If you are only smelling gas with the knobs on, it's possible you have a clogged burner or orifice from bug nests, spiderwebs, etc and need to clean it out first. Hope this helps. Douglas
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
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.
since you can smell gas, you have a gas leak. i would recomend checking and cleaning the gas valves. if you can hear sparking, that means it's just the valves. sometimes cleaning the rods will fix the problem.
Lowly what the potentior does is turn on the burner control system. When you turn on a normal burner you are opening a gas valve and closing a switch to generate a spark. Thus gas flow to the burner and spark. On the extra low simmer burner there is a electric solenoid between the burner head and the gas valve. this has to open as well for gas to flow. What the potentior does is signal the simmer control what level of flame you are requesting and telling the spark module to generate a spark. Once you go to the exlow setting the potentior tells the simmer control what level of heat and will cycle the flame on and off. So when the burner knob was between low and extra low, the flame would cycle on and off. You have to seperate the top section of the cooktop from the burner box to change the potentior for it sits on top of the gas valve for that burner.
sounds like a bad switch in the knob, turn on the defective side, turn on the one that works and keep the clicking going then turn on the defective burner while "other" is clicking if this lights then it means you have a bad switch or loose connections
