I couldn't agree more. I don't think these fridges are defective, they're probably operating within expected parameters given the various climatic conditions. If my beer isn't cold enough, I immediately transition to red wine.

Well, WD40 exists because the first 39 attempts weren't quite good enough......

What is WD40 good for? White lithium grease is a excellent lubricant. Graphite is best for locks. There are products for breaking rust. What does WD40 excel at, other than smelling bad and lingering?

Absorption frig design restrictions.
When we look at the location of the LP burner, the 124V and 12V heating units, they are below the condenser heat exchanger. Combustion gases and hot air rising from the heat required to phase change the refrigerant inhibits the heat that must be dissipated by the condenser above, for the evaporator to absorb heat.

Displacing water from distributor caps (do they still have those) was the only thong I ever used it for.

Gunking up firearms so they malfunction.

WD stands for Water Displacement. If you're not trying to lube something with water in the moving parts, you're using the wrong lube.

Texas Torture Test:
8/7
When I installed my Fridge-Fix fan, I thought I had found the answer to the cooling issue. Now that we have arrived in Texas (100 F), even the Fridge-Fix doesn't help. The temp in the bottom of the Dometic does not get down below 57 F.
8/8
Since most of my perishable food is now questionable, I decided to do another test. At 4:30am, I removed the freezer compartment unit to allow full cooling for the main area. I left the Fridge-Fix in and the fans on to maximize air circulation. By 7:00 AM the temp was 39 F. (looked promising) in the fridge Outside temp was 85F.
I have run the fridge on the maximum setting (120 AC) all day. It is now 2:50 pm and the outside temp in the shade is 105.5 F. The trailer has been shaded all day (trees) and I have been running the A/C, inside temp is 85 F and all cabinets are open. The temp inside the fridge is now 53.4 F
Doesn't look good for summer camping

I heard some people use WD40 to remove Coca Cola stains.

If the limiting factor in the fridge performance is the ability to dissipate heat from the condenser, especially in hot weather, then perhaps a design improvement might be to add a divider in the area behind the fridge so there are 2 distinct air columns, one to exhaust hot air from the burner and heating units, the other to absorb heat from the condenser.
I am also thinking that the performance of the larger 6.7 fridge could be worse than the 4.3, since there is more heat to dissipate. The air cavity is the same width and depth in both models, but taller for the 6.7.

Same thoughts here, the intent when I place exhaust fans at the roof vent will be to divide the airflow so as not to affect the burner flame and concentrate on the path across the external fins.

Somewhere I saw a photograph of a Dometic refrigerator designed for hotter climates that had an pipe over the burner. Looked like a chimney that piped the heat to the upper grill on the trailer.

A few posts ago I described my idea of re-wiring the Fridge Fix fans in series so they would run slower and quieter and maybe have less cooling effect on the thermistor. I gathered everything up today and headed off to the storage place where we keep the Escape with the intention of doing just that. I succeeded in taking the fans, switch, and fuse holder out of the plastic housing but after seeing the way it's set up, I decided to save it for another day. They're very nicely installed with computer style wire looms and connectors, and I would have to have done a lot of cutting and wiring to make the change. I decided to at least try the fans before proceeding.
I've read two or three instances, at least, on the forum of the Fridge Fix fans having a detrimental effect on fridge performance, including one from Reace. Some suspect that the fans are blowing too much cooled air over the thermistor, which causes the fridge to back off. I wonder if anyone would be willing to try placing a cotton ball or similar between the fins above the thermistor to see if that helps. It's going to be a couple of weeks before I can reasonably try something like that. Just curious to see if there is an easy fix for this issue.

I don't have my 21 yet, but what about covering half of each fan with paper to cut the net airflow down?

I think it would be worth trying. It would be pretty easy to put a piece of masking tape across a few of the openings in the back of the fun unit.

The way the fans are constructed, it would be better to put a piece of tape over some of the rear holes to cut down on the amount going over the fins without reducing the intake, any excess should come out back thru the fan motors

I wonder if someone would like to do an experiment with their Fridge Fix fan. This is my next "to do" but I won't be able to try it for several days. Someone who has found the fans to be detrimental to fridge performance, how about putting masking tape across all the hole on the backside of the plastic housing, and then removing the plastic cap inserts on the ends? This should direct the air down the walls of the fridge, which will at least help mix things up, perhaps better than the typical accessory portable fans. If this helps in some way, I think it's worth keeping the fans. If not, I'm probably going to remove mine. Looking for an eager volunteer!
