Newbie with Propane Fridge Issue

I am new to RV'ing (just bought 1997 Damon Hornet Class C this week!) and I have a fridge problem. When I switch to propane, nothing happens. Everything else in the RV that runs on propane is working (furnace, Oven, Stove) but there is no gas, flame or spark getting to the fridge. Where do I start?

Thanks,
Dave "the new guy" In Rhode Island.
