That is what I would do....

Thanks Jim, I did ask and Krista said they put as much insulation in the cabinet as it will hold and that there is an exterior fan. The only additional thing we can do is add a battery operated fan on the inside of the fridge.

Update On Replacement RMD8555

Since I originally started this post last fall and subsequently received a replacement RMD8555, I thought I should give an update...

We have made three trips since receiving the replacement RMD8555 and have been very happy with it thus far. It doesn't leak air like our previous unit! Also, it appears to cool down and recover much quicker than our last unit.

While we haven't camped with temperatures out of the 80s yet, the fridge has mostly been in the 33 to 36 degree range (unless we put a bunch of hot stuff in it). It has even gotten colder than 32 degrees on several occasions. We have even stored ice cream in the freezer.

Also, we are now able to run the unit on propane when traveling without experiencing blowouts. It was 33 degrees in the fridge and 9 degrees in the freezer when we pulled into the driveway this past Sunday afternoon after being on the road for over four hours.

We will see if this performance continues as the summer heat and humidity is just around the corner.

What did you have to do to get a replacement fridge?
We just picked up our trailer after two weeks with the Dometic repair man. He said Dometic is very reluctant to ship out replacement parts. His contact at Dometic told him to disconnect the thermistor . So now we have a refrigerator with the thermistor disconnected. The refrigerator seems too cool better but this does not seem like a permanent fix. I emailed Dometic and asked if it was OK to have the thermistor disconnected. The reply from Dometic was he should not have disconnected it.
Did your replacement refrigerator have the same climate rating of SN?
I am waiting for a reply from Dometic on what our next step should be.

The thermistor is the same as the thermostat on the wall in your house. It tells the cooling unit to turn on and off. The distance from the cooling elements sets the 'coupling' just like your house thermostat.

I could imagine a person telling a tech to disconnect the thermistor temporarily to see how cold the unit can get to. But never to leave it that way.

Sorry to say but you need to find a different shop.

Hi Mary- at Tollroad county park south of Hood River. Outside temps driving from Bend were 87. Fridge now at 47 On electric now so will see if that makes any difference. Never before had this bad of performance in last 18 months.

I question the wisdom and safety of disconnecting the thermistor, but the refrigerator does seem to be working. I could not deal with 40+ degree temperatures.
I am dealing with Dometic right now through email so I have everything in writing!
Since my refrigerator is new and under warranty it should be their problem not mine!

Rousse another thing to do is take the thermistor out of it's holder and I have mine just hanging there . Did you change to the newer 2 door ? If you haven't you could remove freezer that will also help . Hope you have a fan inside too . Pat

Hi Klem can you please tell me the thermistor out of it's plastic holder is Ok ? Mine is short so it is in the general area anyway . Or are we talking literally to disconnect thermistor ? Not Ok ? Pat

I noticed the picture only showed the disconnected wire going to the thermistor. Here is a picture with the thermistor attached to the fins. If we were not under warranty maybe we would try something like this http://dinosaurelectronics.com/Dom_adj.htm
If we stay with Dometic as our refrigerator it will always be under warranty.
Our fridge is on the #3 setting @ 35°
