Dometic refir not cooling well

[bumpersbird]

God, I love this web site. I have all of the symptoms you guys have
been describing and then some, the ice maker also leaks when turned
on! Turn it off and the leak stops. Freezer works great. Never cool
enough in the fridge for safe long term food storage.
My PT42 has an angled fridge and the compartment it is mounted in is
cavernous.
According to this site, http://www.rvmobile.com/Tech/Trouble/vent.htm
This configuration is not good. There is too much area for the
convection process to do its job.

I was in the process of installing cooling fans in the engine
compartment and inverter bay, so I guess I'll just keep moving around
the coach to the fridge compartment.
According to the above web site, they state that direct cooling of
the coils is not appropriate. But there is a problem with this! The
specs given for a proper installation are less than 1" from the coils
up to the roof, so you would have to put in ductwork and maybe some
baffles from the side vent up to the roof vent. Not really what I
wanted to hear. The space is so large behind the fridge that I
believe direct cooling with small fans is the only practical way of
venting this set up. Some of guys on this post are doing this and
they are having good results with it. In addition some type of power
vent in the roof to extract the hot air would also be good. A max air
would defiantly do it, but mounting it in place of the fridge vent on
my coach does not look encouraging at the moment.

I believe it will have to be a set up on the inside of the fridge
compartment. Not really a problem I have to pull the fridge to fix
the ice maker water leak anyway. And there is enough space behind the
fridge to mount just about any type of fan system you need. I may be
wrong but I think a fan in the side vent won't help as much as a fan
in the roof vent. The idea being that it's a convection system and
moving air past the coils and extracting it from the compartment is
how this was designed to work.

I'll be watching these posts with great interest, any thoughts or
ideas would be greatly appreciated. As soon as I'm done with the new
engine compartment fans I'll post the results and pics, this may not
be practical but they were fun to put together. 2 - 16" 2500 CFM fans
on the louvered door curb side, 1 small fan in the opening between
the inverter compartment and the engine compartment. 2 – 14" 2000 CFM
fans on the Air Cooler and Radiator, and 1 or 2 fans on the A/C
condenser size yet to be determined, all fans are thermostatically
controlled with manual over ride. Oh yea, fans in the A/C compartment
