Dometic RM2607 Refrigerator problem

just .02cts takes about ten hours for ours to cool. and your in a hot area.

Try putting a bag of ice in it to help speed up the cooling process. An empty fridge takes longer to cool down than a full fridge.

Let it run 24hrs first.

Check the refrigerators door for air leaks

Read the manual. The fridge part temperature is adjusted by sliding the thermistor on internal fin on my model.

Thank you for the replies. I put ice in the bottom drawers of the reefer and a bag of ice on the top rack, turned the reefer onto propane and started driving. When I got to my destination 4 hours later the thermometer in the reefer was at 40 degrees and it is still at 40 degrees this afternoon with the temperature hovering right at 100 degrees. It just surprised me that the reefer wouldn't cool as well on 120 volts as it did on propane. Wonder why? (and yes, the thermistor on the fins is up as far as it can go)

I had the same problem with a Dometic in my old Class C and replaced the thermister with this

Snip the tip

It made a world of a difference..Problem solved...

We've discovered (like the OP) ambient conditions can significantly change the amount of time it takes these fridges to do their initial cool-downs. We've seen our Dometic DM 2663 cool down to 40F within 4-5 hours with ambient temps below 75, and as long as 12-16 hours with ambient temps above 100.

FWIW, our 18-month old DM2663 3-way fridge cools equally well on propane, 120vac, and 12vdc. It reaches 190C deg (375F) flue temps using all 3 power sources.

Interesting reading. I've been having similar issues.

I did some fridge testing couple years ago and 120V and propane had not noticeable differences in cooling.
12V element was lower output thought.
I recheck my thermistor and it is all the way down. I think your should go down too.
