Refrigerator warms up when driving

Thanks Doug, I suspected bad air over the top and bottom vents when driving since my awning arm sticks out about 3 inches and is about 5 inches in front of the two vents which would creat a lot of turbulence. So last night I got out the ladder and removed the upper vent cover and there was a lot of heat up there but the factory fans were not running so I installed a jumper wire to make the fans run constantly and the refrigerator cooled down faster the usual and I will see how it does on the way home tomorrow.
P.S. I almost went residential fridge a few weeks ago since it stopped working on me but I figured while I was pulling it out I much as well try turning it upside down before just replacing it and it started working again. I already did all the measurements to see what would fit but since it started working again I figured I would save my money for the moment.
Thanks I will let you know if it keeps temp better with the fans on, if it does I might relocate the fans up to the grill.

You are confusing the operation of the refer with your problem. LACK of ventilation or a air flow problem will NOT cause such a drastic interior temp rise after driving a few hours or even all day. Your problem is the refer is pulling in outside air. There are 2 ways for the refer to do this. The 1st is what I stated earlier. The 2nd(if the CU had been replaced) would be inadequate CU to the box sealed correctly. If it is the original CU, then this is not the case. IF the CU has been replaced, then this may be the case. On a correctly functioning RV refer you could turn it OFF and drive and probably have negligible temp rise in transit especially 20 degrees in the freezer. Remember, YOUR model is a rarity in that the Freezer has an outside egress for drainage of water and 99% of RV refers the freezer has no such hole. Doug
