My sister and I have just returned from our first trip, in our new to us, 2001 coachman pastiche 5005/5. For some reason the fridge would not run off the gas. It has an automatic ignition system which just kept on ticking and flashing. We checked the safety valve, but still had no joy. Given that we are two women, please keep the answers simple but any thoughts before we call someone out to take a look would be appreciated.
