I believe the spark control module is bad on my range and need to get the part number off of the module. Before I strip the nut on the burner base which is under the burner cover, I wanted to make sure it's the correct way to remove the burners. Also,is there a special tool since this looks like a very thin nut made out of soft metal at the top of a sleeve that goes down into the bottom of the burner.

Sorry for the typo. The correct model is PRG304.

Thank you for the correct model number.

Did you perform any troubleshooting? Why do you believe that the spark module is the culprit?

The spark had been becoming intermittent for a couple of weeks since the multiple power outages we endured post Hurricane Sandy here in NY. Then the other night all four burners just quit. No spark, just gas. We've been lighting it the old fashioned way, with stick matches. I figure a power surge or spike took out the electronics. I did unplug the stove for a bit in the unlikely hope that it would miraculously start working! I can't troubleshoot any further until I can access the spark module, and that I believe requires removing the drip pans since it's shown in a box under the left side burners. I just can't get the venturi to budge with WD 40, box wreches, sockets, even vice grips.
I just consider it another of the many problems I've had with this overpriced stove that eats oven ignitors at least once a year, has had oven door problems and convection fan problems. Next breakdown will definitely prompt replacement. Thanks in advance for any advice you can offer.

Very likely the problem is a bad spark module but, before you will go further I would recommend to verify 120 VAC to the range.

Removing these venturies is a real headache. You can not force them too much because you can easy break the gas supply tubes. The best solution based on my experience is to cut off the venturies using a dremel tool. In such case you will need a new venturies and new jet holders.

Thanks for your help! I was afraid I might have to cut those. I have the dremel tool at the ready. Verified AC to the stove both by the fact that the oven does work and the oven light is on. Just to verify before I order, the et holders are listed in the parts list are burner bases? Not a stove guy so I just wanted to make sure. Second, is the 6 point re-igniter listed the correct part for my 4 burner unit with simmer control on the left burners? Thanks again

The jet holders are listed in the parts list "Burners & Grates" - #9. There is only one part number. If all burners are the same size then it's fine. If they are different, you better call APP CSR to verify it.

I found the 4 point re-igniter but I'm not sure if it will match up with the wire plug.

- The 4 point re-igniter Part number: 189323
