Why is there no gas flow to griddle burner?

Could be the igniter isn't sparking, sometimes they get cracked and run to earth you will still hear it click. Remove the top plate and check the wiring and igniters, turn the lights off and you will see if it's sparking all over the place.

odds are the ignitor needs to be replaced. It glows but doesn't hot enough to turn on the gas. Happens to me about every 2 years

This range has a standing pilot light for the top burners and griddle top. If you look through the small hole under the flat top griddle you can see a small line about 1/4 inch that runs from the main gas manifold to the pilot light about 6 inches back under the griddle top. You will need a tightly wrapped piece of paper or a long match or small wooden stick, like a chop stick. Light the end of your paper, or stick and put it through the hole all the way to the pilot light. It should catch on fire. Whenever the main gas line is on, the gas will flow through the pilot light. If it will not light, there is a pilot light adjustment that is a very small screw in the middle of a 1/2 inch square metal fitting that is screwed into the gas manifold. If the pilot won't light, this screw may be turned all the way in, thus cutting the gas off to the pilot light. If necessary take a very small flat blade screw driver and turn the screw counterclockwise a half turn. That will increase the gas flow to the pilot light. Another way to light the pilot is to put your burning stick or match into the hole near the burner under the griddle plate, then slowly turn the heat valve to the on position. The main burner will light and then the pilot will light off of it. Don't get your face too close to the griddle when you light it, gas can flash back into your face.

I just had a tech come to my house and he told me that I need a new glow plug, It's the box to the right of the flame. Looks easy to replace, his visit took 5 minutes and it cost me 143.95 (this doesn't include the cost for the part or to have him come fix it, that will be sometime next week) so if you can get the part and do it yourself I would suggest that.

If it's two burners on the same side that won't light, it is probably the igniter for that side. If so, remove the grates, griddle, and griddle sub pan, and then lift up the main "pan (if it's like mine, it's hinged at the back and lifts up). Now, if each burner on that side has a tube going to the middle between the burners, the igniter is in that middle section. Mine is a small plug-in ceramic and metal part (see photo). If yours looks like this, contact me at [email protected], I have a spare.

Make certain the burner and burner base are very clean by carefully washing in warm soapy water, using a plastic brush to scrub any residue off the surfaces. Also clean the spark ignition nub in this same way.

part number for the griddle is WB31K10140
partstore.com has it for $87.95 hope it helps

sounds like you have a bad switch. maybe on the large burner.. some of those switches can be replaced without the whole harness.

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.
