Refrigerator won’t work on propane

[marcee]

We just got back from a 10 day trip from California to Oregon. Driving to Oregon the refrigerator works on gas. While connected to electric at the campsite the refrigerator worked fine. However when we disconnected the electricity the refrigerator did show it automatically went into gas. We could not hear the pilot turn on and the refrigerator never worked on the way home. The propane worked for the stove so it appears it's just the refrigerator not working. The propane tanks are not empty, the trailer is level any idea what is happening? 21BHS
