There are really two issues at play. The substandard err subnormal refer and ETI failure to follow the dometic installation instructions during the installation. Failure to insulate around the frig and building a baffle to obtain a one inch space behind the frig to create a good thermal chimney.

Well for what's it worth they will work some effort. Just returned from 4 days of 95+ degree miserably hot camping. Fridge side of camper was in direct sun in the afternoon. Freezer was removed and only the Dometic fan running outside and a 12 volt fan running inside. All food was cooled down before putting it in the fridge. When we opened the fridge I would think about what we needed and get it all out in one opening and put anything that needed to go back in back before it had a chance to warm up. I would shut the 12 volt inside fan off before opening the door so as not to blow the cold air out.

Set on 4 bars we had a high of 36 degrees and a low of 32 degrees

I did get to work on a fridge but it was on a Casita and not mine for a change.

Dometic RM8551 insuffucent cooling

Tom, I think your post as well as many others proves one thing: there's nothing wrong with the cooling units on these fridges. The problem lies with a lack of insulation within the fridge cabinet itself (necessitating the addition of exterior added insulation), and inadequate airflow over the back. Really good to know it can be made to work. It's just a shame that it takes such mods to accomplish that.

C'mon Dometic. Sell a properly insulated T-rated fridge in North America.

Hi Tom . ? Your outside fan - how long did you run it . Remember I am in complete control of the fan . Should I watch temp back there until it reaches a temp ? Or turn it on and keep it going until it cools down outside at night . Any more idea's ? Pat

While all of the data to date is antedotal, I'm coming to the same conclusion, Robert. The logic of better insulation and more effective and efficient airflow at the back of the unit is kinda hard to argue with.

I have not installed the snip the tip. I have just pulled the sensor out of the bracket and have it hanging in the air. When it was taped to the wall I think the wall affected it. Seems to work better just out in the air. (This one is for you Parker )

I would run the fans all day and shut them off when I went to bed and turn them back on in the morning.
