Captn America, Ours acted like it could have been the thermister, but in the end it was strictly condenser ventilation. Any easy way to force some air across your condenser?

Billcin Have you tried running it with the cover off? If it works like that you've diagnosed the problem and can move on to working on a solution.

To both: Ours is a smaller trailer, no slide and vents through the side of the trailer at the bottom and top of the reefer. Removing the top vent grate fixed the reefer. If you can't get rid of condenser heat you can't get evaporator coolth.

What kind of trailer do you have? In my last post I posted a picture of the top vent of my refrigerator. Does your top vent look the same with the cover off?

Wildwood 195BH. Vents look similar. About the same width but not as tall. You look in the top vent hole directly at the fins on the condenser.

The problem seems to be the design of the vent openings, guess they were trying to keep bees, wasps and water out. It's most effective at restricting air circulation. I couldn't even get fans to push enough air through it.

I've got a floor register cover I'm about to install in place of the vent that will let me flip the lever and open or close the slats. That should let more air through and also let me close the slats to keep rain and bees out. I'll post a picture if it works.
.
In the meantime, pulling the vent cover like in your picture does the trick, but it ain't pretty.

Thanks Lefty665. I agree, the ventilation set up is flawed.

That's being very polite.

First time we ran into it was at Arches in July a couple of years ago. I pulled the cover to see what was going on and the blast of hot that hit me in the face was diagnostic. Neither DW or I were very happy. However, with the cover off the heat dumped quickly. A half hour later temps were getting better in the reefer and I'd solved the immediate problem. There was nothing else to do for it in the middle of the desert except relax and enjoy the scenery. We both did have some less polite words for the design geniuses at Forest River. At least they let me get the vent cover off without tools. Guess they knew it would be a frequent happening.

I wonder how many Dometic reefers have taken the hit for Forest River's failure?

Exactly! My first refrigerator was a victim and I wonder how long until the brand new one perishes from the design flaw?

Forrest River finally said they will replace it! July 5th my trailer went in and picked it up on July 15. Dometic had the dealer test the unit on gad and electric to make sure the refrigerator works. It worked fine probably aware of the ventilation issues and when this new refrigerator fails, as I am sure it will, Dometic will then say it was installed incorrectly. Which I think it is. I will let you know how it goes, as of now refrigerator is at 38 degrees with outside Temps of 90 degrees. What year and model is trailer?
UPDATE Ok, Forrest River and Dometic did replace my DM2652 as promised on July 14th. 1 small fan installed just below the black canister on the bottom of the refrigerator. So far the temperature fluctuates between 33-44 depending on ambient temperature. I am happy for the time being.

Thanks TURBS! I just saw this today. Talked with a dometic rep. Gave me some suggestions. unplug thermister etc. Did not try them. FW is actually headed back to factory. Having them look at it. This has been put aside by me for now. Thanks again TURBS!
