My gas stove top burners are dying. I only have a large burner left, with no plans to replace the stove top until the last burner dies.
My problem with the large burner is I exceed the amount of pressure needed. I did green bean quarts-12lbs for 25min. but the with the burner on the lowest setting it was creeping up to 14-15 lbs. the only way to lower, was to turn on and off the gas to maintain at 12lbs.

It it dangerous for me to be turning off the gas? If the pressure stays above 12lbs, it's still maintaining the heat, right?
