Jim, have you done the insulation fix in the door? It seems to me that right now that is our best hope until Reace gets something back from Dometic

Pushing air around all the hardware will create a fair amount of turbulence that could reduce the net airflow compared to pure convection and a more laminar flow; when I get my 21 home I plan to put fans at the top vent and see if sucking the air out helps.

Before you spend to much time mounting a fan up high which requires either removing the fridge or roof vent, try installing one in the lower part of the fridge which is much easier and try it.

I installed one high and one low and have found the low one by itself works as well as the upper one. I was kind of surprised by the result of the upper one and expected it to work better then the lower one.

If you getting the Texas fridge option I'm not sure where ETI mounts the fan.

Also yesterday I open the fridge door and drove the fridge temps up from 31 to 39 and in the heat of the afternoon (88 degrees, 87% humidity) I was able to pull it back down to 31 in 3 hours.

I have exterior fans but have not ran them so I could see what it would do. I have had a little interior fan running.

Maybe its just wishful thinking but the fridge seems to be working better.
Tom, Just wondering if you continued your experiment,and if so, what the results are today. Thanks.

Currently 92 outside, 88 inside, fridge on electric @ 4 of 5, 40 degrees in refer and 3 in the freezer, completely stock unit. Oh yea, the fridge side is in direct sun since about noon, also have had the ceiling fan on all day on exhaust. Of all the testing and mods many have been doing, has anything actually made a difference?

I did the plug at the bottom of the door but not the entire panel removal yet. My Maxxfan is not running right now. Have not done the candle test yet.

I figured I'd take off the vent cover and see what I have to work for space for mounting the exhaust fan on the outside of the bug screen. The screen itself blocks a lot of airflow, so if a fan makes a measurable difference without the bug screen blocking airflow, seems like a flapper style exhaust (like used on clothes dryer vents) might provide a higher flow volume when the fan is on but still close to keep the bugs out when the fan is off. I didn't order the Texas fan option.

Yelp, fridge is still running but I do have freezer removed. We have decided that because we don't use the freezer that much we would rather have the additional fridge space, extra shelfs, and added cooling capacity. I have left it on 5 bars most of the time and it has been sitting on 30-31 degrees for 3 days now. No exterior fans running, small interior fan running inside the fridge. Max ceiling fan is still running. If I drop it to 4 bars it runs around 35 and 3 bars runs 38-39. If I was to run a outside fan I think I could actually get it to 29 if I wanted a big freezer because my thermometer has max/min readings on it and it has shown 29 degrees once. These reading are on the door which should be the warmest place in the fridge.

Outside temps have been around 90 degrees and 70%-80% humidity.

It appears the latch fix has done more to help the fridge then anything else I have tried and I have tried a lot. I am fairly confident from doing previous test before the latch fix that even with the freezer installed we would be able to get good cooling below 95 degrees. Above 95 degrees who knows, I don't plan to camp when it's that hot if I can avoid it.

Hi: KountryKamper... This sounds most promising. I'm looking for some foam to fill the latch rod space on our fridge. Maybe with that done I can turn it down a few bars!!! Alf

I should open a website and sell the stuff. We have several 3'X4' sheets of it left over from a job we did. One sheet would probably fix 50-75 campers. Problem is it cost more to ship then it's worth.

Maybe Dometic will supply it as a fix someday already cut out.
