Our Norcold refrigerator in our 2005 Holiday Rambler runs on electric but does not run on gas.....we were driving back home after a great few days out, and while on the road it started beeping, before we left it did start to run on propane. We tried to re ignite it, but it would not ignite, we could hear the clicking trying to ignite but no luck. We are not out of propane....any suggestions??
