Mine is a 2015 grey wolf 21rr. Can't tell you the maker of the fridge freezer but it only has one button, on or off. It will automatically source to 110 when present instead of propane. When no 110 it will go to propane. When operating properly on 110 the light will be solid green, when propane amber, red is a problem. If the led is flashing on propane I think it means low propane
