My
refrigerator did the same thing . 120 VAC worked great , gas would not get cold (48 t0 55 Deg F). Turned out that the gas pressure regulator was set at 8 oz and the
refrigerator needs 11 oz. . P.O. had screwed with the regulator and lowered the gas pressure because he thought the stove flame was too high? Now the
refrigerator when running on gas and the thermostat is set at 4 stays about 34 to 38 Deg F (Dometic 2 way 4.6 cu ft.)
