On our 6 burner gas coocktop, the right two burners don't light
On our 6 burner gas coocktop, the right two burners do not light easily. The ignitors are popping with spark, but it seems that the knob is out of time, and when you get the gas turned on enough to light, the clicking goes off, and the burner does not light.

Re: On our 6 burner gas coocktop, the right two burners...
Electric gas igniters sometimes get stuck in one position causing a clicking sound. The clicking sound that you hear is the electric arc that is pulsing from the igniter conductor (wire) to ground (the gas burner). It receives power from the electrical outlet that the stove is plugged into.
Residue from food and sometimes cleaning products may be preventing the igniter from producing a spark (Arc) to the base of the burner. This is a common problem that occurs when the stove has been cleaned or food is allowed to build up. Make sure that the igniter and the burner base are clean and dry. This will help with proper operation. Oven cleaner and a small tooth brush may be used to accomplish this. Another problem with ignition may occur if you have too little (touching) or too much space between the igniter and the base of the burner; it will prevent the burner from igniting. You should only have a little more space than the thickness of a nickel between the burner base and the igniter. A good “blue” arc from the igniter to the burner base is optimal. If this doesn’t work, you may need to replace the electric igniter module. Good luck.

Center burner won't light: If there is a bright spark (check all ignitor points at night with the lights out and look for consistent brightness of the sparks) then it's likely that the burner slots are dirty or the air/gas mix is wrong. If you can light with a match, but the spark won't light, then go for cleaning the entire burner assembly thoroughly with a brass bristle brush (available at most automotive stores). The proper air/gas mix has to flow over the spark to ignite. Weak spark, improper air/gas or misdirected gas flow that misses the spark can all cause this issue.
RR burner lights only on low setting. Again, check the air gas mix and clean all parts. Something like a small spider web inside the air mix chamber (area between the orifice and the burner can cause this and is difficult to see. Disassemble, clean thoroughly, reassemble and test. Extra low simmer burners (two on the left side) use their own control module with electric gas valves and variable electric control switches. The burner works on low, so these are not likely the problem.
Most folks want to find a bad part, and that can happen, but stove tops get dirty and cleaning usually helps. If not, you have a clean top to work on.
The indicator lens and/or the retainer are either broken or the retainer is missing. It's best to replace these as they are not expensive. When the top is off while cleaning is an perfect time to replace the lens.
A common problem with that type of ignitor is that the porcelain insulator (much like a spark plug has) can crack easily. When it does, there will be a clicking sound, but the spark no longer arcs from the top of the ignitor post to the burner and cannot light the gas. Without an intact insulator, the ignitor is effectively shorting out and needs to be replaced.
the very first thing i would do here is to check the ignitor itself
under the head cap you should see two screws, once those are out you will be able to lift the burner plate, lift the burner plate, you will see, or should see the ignitor, and the wire.
i check this for voltage by unplugging the ignitor and olding the wire close to a ground, the metal body is good. Turn on the ignitor, becareful it is live. yhou shgould see a spark comming from the wire
if not check to make sure that wire is in position and on the spark module
if you do see a spark this way, just order the replacement ignitor
and install it when it arrives

One burner doesn't consistently light. Igniter sparks but not the same as the other - "good" burners spark at top of igniter and moves around to light, "bad" burner sparks toward the bottom and doesn't move much. I can use the burner by lighting with a match and it works fine. Have tried cleaning with a toothbrush without much success
aknot, make sure each burner cap has a good ground to the burner. You can use some light sandpaper to scrub them. Where the burner fits around the ignitor is a small orfice. Use a paper clip or small sharp object to clean out the orfice. Try this first. Catriver..post back.
