Not sure of your type of oven pilot, however there was a time when gas ovens had a constant pilot light & when you turned the oven temp control on, it turned a secondary heater pilot , which in turn heated up the oven safety valve. Once the safety was heated, this in turn made the gas flow to the oven burner. When this system first came out we had a lot of calls as people would turn the oven on thinking the oven burner should come on. When it didn't they of course turned the burner off, thinking gas would be leaking into the oven. you may want to look at the (2nd) pilot light to see if a small tube is in the flame. If so, & the oven burner does not come on, then the safety is shot. I really hestitate giving suggestions regarding LP gas, as if not handled correctly, can cause serious harm. PLEASE, IF YOU DO NOT FEEL QUALIFIED OR COMFORTABLE,THEN TAKE IT TO A REPAIR SERVICE.
