I took this range apart yesterday after one xlo burner would not ignite. It appeared the selenoid was not activating. I was in the process of swapping the pot wiring at the simmer control board when the pot #2 wire accidentally hit ground. This caused a spark at the pot and now xlo burner 1 and 2 are both dead with no gas or spark.

I see there is a rebuild kit that includes 2 pots and a new controller. AP3572616. Should this fix the problem and why does the item text recommend a factory service tech for this?

Just to make sure, I measured low and high voltges at the simmer board to make certain I did not nlow out something upstream. All fine.

I'm up for buying the kit if it will fix the problem. Just want to make sure I didn't cook anything else when that #2 pot wire hit ground and fried!

Thanks...hoping Gene the Thermador expert may lend some advice.
Much appreciated..Jim S.

Yes...silly me....I didn't pull the plug first!

I would have swapped at the selenoids but I did not spend anytime getting access from below....and decided to go the swapped pot route instead to see if the problem swapped. Oh well....poof it went.

I am, however, curious why spark quit at the #1 and #2 burners, though when I firied only #2. Spark was happening at #1 before I fried #2.

Not anymore...BUT...if the kit will fix the issue that's great and it looks like that's the only way I can get the pots now anyway. What would be a pain is if it was the selonoid all along and I have to replace that too after the kit..but so be it!

Thanks Gene....Jim.

I put in the replacement pack into my range. I found it relatively easy to do.

We're glad you were able to fix it.

Gene.

It could be a bad simmer control, but I've seen situations where the voltage going to the simmer control from the potentiometers has dropped to around 100vac or less. When the voltage is this low both exlo burners will quit with no spark or gas. The way to check this is to remove the wires on POT1, POT2 and Line-5V. Measuring from the wire to chassis(ground) you should have ~120vac. If you find an extremely low voltage you can trace the wire back to the potentiometer and check the connection. POT1 goes to the front and POT2 goes to the rear. Line-5v goes to both.
If you find a good 120vac from all the wires to chassis then install the kit, Thermador part number 497235.
