I mounted my two fans directly above the burner so they blow the entire length and width of the back.

Direct wired heat element all night. 20 hr's. Only got down to 40 in frig. Guess heating element is the problem? Time to take it in for service.

dcheatwood, what fridge do you have? I have a Dometic RM 1350. I have notice temp getting up to 45 deg on hot days.
I did add screens to my openings in the vents top and bottom. Wondering if Im restricting too much air movement.
My fans do blow upward. I have no wall or baffle in my top vent like in your pic.
Just a note on that: dealer had to make a wall of caulking (1 1/2" high) to stop rain water from coming in the top vent and running down on my floor inside.

A good airflow across the back of the unit is much needed to dissipate the heat.

Mine is the dometic 2652 if I'm reading it correctly. Thats the number on the tin plate blocking the flue. I've made several mods trying to get it to cool like my others did. The new thermistor is the only one that made an obvious instant improvement. I'm still waiting for a hot day to test it.

Have you tried the dual fans on the back?

Yes. I posted pictures and step by step details of the mod. Didn't seem to help. I have the ori fan still on its auto system and manual switch on the two new fans. I really believe I had a bad thermistor but can't be sure until weather gets hot here again. With the new thermistor, on factory setting, it's holding down to 28 at night and up to 35 in day but cool days have been in mid 70s all week with rain and cloud cover. Should warm up today and tomorrow.

Yours is unique as the 1st I've heard with 2 or 3 fans blowing CONTINOUSLY on the back did not lower the inside box temperature.

They'll surely matter on a hot day but it would not come down cold like it is now.

My fridge is a DM2862. I hadn't seen any cooling problems, but, it hasn't really got hot yet. I threw this computer fan in there right before we left the other day. Just mounted it to a piece of aluminum flat bar I had and screwed it to the frame work. Tight fit, but it doesn't touch anything. I just mounted a toggle switch for now. Hope to put a thermostat switch and neaten up the whole deal later on.

Only fridge I had problems with as far as cooling goes, was the one in our forester, in the slide. In that case, replacing the thermistor with the adjustable one (snipthetip.com) did the trick.
