3. If I had to guess, I would say faulty/dirty flame dectector or wiring to it.

Modern gas burners have a safety feature of a optical light detector that shuts off the main gas flow if a flame is not "seen". it will allow the gas to come on when the burner is activated, but if it does not "see" a burner flame, it will shut down the gs flow to the burner. Basically to keep your house from filling with gas if the burner doesn't light or goes out for unknown reason.

That said, I'm no expert and I would have service person look at it.

That makes sense (and also might explain why banging on the glass might make a difference) hlthe2b Jan 2013 #4
