Fridge cools better on 110v than propane? any Ideas

Thanks for all help in advance, I have a 1992 Scamp 16 footer. The 2-way fridge has not been used mucht in the past 2-3 years (old Owner) I fired it up in gas and it did cool, but not very well. It would cool to 48-50 F in the fridge, now outside temps were running 60 lows to 80's for the high, I was not using any heating or air in the camper. I turned the fridge to 110 and and it has been keeping the fridge temp at 38 to 40 for the past 2 or so months, unless the outside temps are super high. Had way to many days over 100 and the camper is parked, so no a/c running in camper. I do understand that if its 107 F outside the inside temp of my camper is prob. closer to 120 F and the frige will have a hard time keeping up. I just dont understand why it would work better on 110v than propane. The camper is level both front to back and side to side. Thanks again Jim

Not sure how long you waited while on propane but sometimes it may take 6-12 hours for it to totally cool down. try switching it over to propane now that you have it cooled down and see if it changes any.

Some refrigerators have a hi/lo flame connected to the gas thermostat. You might check and see if the gas thermostat is set to max and look to see if the flame has both the high and low level working.
If you have a Dometic, there is a master service and troubleshooting manual available on-line that is very user friendly and covers most models over the past 30 yeasr

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.)
