Thank you Gentlemen!
Steve & Jage I read your posts about refrigerators before posting.
Jage thank you for your idea of pulling the fridge out 2" and doing a test. That wouldn't have occurred to me. I'm going to do that.
Steve thank you for directing me to the part of your post that said the 2nd fan made an improvement. The coils on my 2007 fridge unit (1994 van) are flat across the back of the unit. Not like the ones that are in the corner. Also there is not a back to cabinet just A/C ducts up against the insulated van wall. They just shoved the fridge into the ducts. You can see the indentations in the A/C ducts. Hmmm, just gotta wonder? Oh well, if there is an improvement with the unit pulled out 2" then I'll look at a your 2nd fan idea.
Thanks guys for the great ideas!! This will help.
