Dometic refer warms up on cool nights

[Kanga99]

We are camping this week at Mesa Verde NP where temps are ranging from mid 70's during the day to give or take 40 at night. Our Dometic refer runs great during the day keeping interior at about 30-36 degrees. Problem is that at night the interior temp actually goes up to about 40-42. DW is worried about spoilage. Freezer is fine. We are supplementing first thing in the AM with ice packs but should not have to do this. We do not tend to heat trailer overnight unless it drops below freezing, just turning on the furnace to get the chill off when we get up. We are running on AC. Cooling fans are cycling but not much at night. Roo 23IKSS. Any thoughts or suggestions?

That does sound unusual. There is generally little, if any variation in the fridge temperature during night and day. If any, it's a little colder overnight.

If you're currently running it on 120V; have you tried running the fridge on propane to see what happens?

Is there a fan in the outside rear of the fridge

Yes, there are 2 small fans and a thermo switch on the coils behind. The fans cycle less at night. I know that since they are so damn loud. BTW, My next upgrade is quiet fans. This fridge is in a slide out.

Thanks, will try this on next cold weather trip. For tonite will add ice in refer. Tomorrow, on to Moab so should not be a problem.

Thanks for the video link. Good information!

I've added an additional large throughput fan at the top of the stack. I did that, because we camp in very hot areas and the additional air flow makes a big difference during those hot temperatures. I debated whether to have it on all the time or come on with the sensor. I am now glad I decided to sensor it. We camp all year round, so having the fan off will help on the colder nights.
