The 3 way refrigerator in my rv has always put out low temperatures prior to traveling or sitting in one spot for a long period of time. I've added 2 fans in the condensor area, a fan inside the unit which is blowing against the evaporator all to no avail. I'm pretty sure that the problem has to do with a heat soak issue because the refrigerator is mounted about one inch above the floor and that floor area has the muffler underneath it. I've recorded a bit over 100 degrees Fahrenheit in this floor area from inside the coach. There's nothing I can do to try to insulate the floor either above or blow it because there's simply not enough clearance. So I'm just living with it.
