Around here stove top burners are commonly called 'eyes'.
I suspect that you have a failing regulator as well.
Will the furnace run?
Will the water heater run on propane?
Most local RV stores will have regulators in stock if you need one quickly. Most LP dealers will have them as well. Just make sure you get a high flow model and not a grill regulator.
While not strictly required in this situation, it usually helps to know the model of the RV and appliance we're dealing with.
