Have a Dometic fridge in a 2000 Terry but doesn't like to light. Can turn it on inside but the delay between propane supply and spark seems to be a touch to long and by the time it trys to ignite the propane blows it self out because of the "mini exposion" Just like when lighting a propane torch with the gas turned to high. Also likes to go out easily at times. Can take a lighter and it will light just fine. Could my regulator be going bad or any other suggestions.
