I installed a NorCold RV refrig, tempararily until I could finish my built
in frig/freezer sysem... The OEM insulation is about 1" think and the door
gasket doesn't seal very well.

However I had some of that foil and foam insulation blanket material (multi
layers, in a 1/2" blanket). I wrapped the outside with this and moved the
refrig condenser coils back enough to get a layer between it and the back of
the box..

I was surprised that the run time cyles were reduced by 25% and I hadn't
done anything to the door or it's gasket seal problem..

I plan to do the same thing to a NorCold chest freezer I found at a thrift
shop. It really runs a lot if I have it set below 10 deg above zero.
(however, it really does a nice job of keeping the ice cream and meat
frozen.) Hopefully a similar wrap with this foil and foam blanket stuff will
improve performance.
