R U sure it is dead? They don't make them like they used to, but a non-compressor based RV fridges can work for 50 years, no sweat. It is usually is not dead unless it has blown ammonia refrigerant outside (or inside where your life would be endangered and no insect would survive/reinhabit for years). If you didn't get a whiff of ammonia, it may be sick but isn't dead. Wiring contacts can come loose, and one or two red faced members have gone shopping for a new fridge only to realize the plug had shaken loose while traveling, or a lead had come loose from a circuit board .... duh. Free fix!
To my limited knowledge, the cooling unit on ALL RVmodels can be replaced with a refurbished unit easily, and for a fraction of the cost of replacing the whole box.
Today is a gift, that's why they call it the present.
