We in the commercial cooking equipment business are experiencing a reduced quality in parts, due to the fact that most replacement parts are now assembled in other countries such as China, Taiwan, Mexico, and others. There's very little attention invested in quality, only quantity. I recently had a run of six faulty thermostats on a Wolf griddle.
The popping noise at the surface burners is common to propane operation, and it's harmless, unless there's a constant flame at the orifice hole. If there is, it will cause soot buildup in the burners.

When the oven failed to light the pilot was still operating. Just now I tried to light the pilot without sucess. Is it possible that the T/C's have failed? T/C $10.25 vs tstat $175.63.
OK, When I press the Pilot button no gas comes out for the pilot to light. I held button while appling a flame for about one minute.
Here's what I have done so for to check pilot/Tstat oeration.
1. Checked T/C connections on both ends. Pressed pilot button. No pilot gas.
2. Disconnected pilot supply tube from safety valve, pressed pilot buttton. No gas.
3. Reconnected to valve and disconnected pilot supply tube from pilot assembly, pressed button. No gas.
4. Cleaned pilot orifice (per your instructions), pressed pilot button. No gas.
5. Placed candle under the T/C and waited 5 mins. Turn oven tstat to On . No gas flow.
6. Turned on second oven (separate valve). operation normal.
Can you think of anything else to try before before I purchase the overpriced chinese crap?
Thanks for your help. Your answer is acceptable.
