1. The LP on the refer. Only 3 things. A. Dirty Burner B. LOW LP pressure and you need a manometer test to determine that. C. If in a slide out room the Rubber LP line is being pinched.
2. There are some Trailers that have 3 AC units and even with 50 amp service, the OEM's install a 2 out of 3 Compressor run kit. Try running the malfunctioning AC alone and see if it cools. These kits prioritize the AC units. Usually the Bedroom ALWAYS has power to the Compressor. The LR and Garage AC, the FIRST one to be run that locks out the 3rd. This system is very rare. Only lasted for a few years. Odds are you have a problem with the AC unit. Doug
AS to the freezer versus the lower section of the refer. The freezer in an RV fridge will always get colder with a malfunctioning LP system. The Freezer will get down to 0 to 10 degrees. The main refer will be 32 to 38 degrees.
