I was thinking a better set up would be too keep the fridge doors the same height but add the compressor and condenser on top after all our ceilings are 8 ft high.

"mnrenovator are you sure your's blows air out the front?"

Yes, when I cleaned the coils a couple of months ago I took a good look. The coils are the full width of the refrigerator compartment. There is a fan that pulls the air through the coils and the exhausts it under the freezer side and out it flows out the front. Basically the freezer side is like a duct. This also helps with passing the warm air over the defrost water to evaporate it out quicker. The back of the fridge has no vents its a solid chunk of brown masonite or similar material in that area so the air doesn't have a way of readily going to out the back.

Looks like I'm going to have to pull my fridge out too now! I don't know if the coils are on the bottom or back... I too couldn't put insulation around the sides of my fridge, but I could probably put some on the back/bottom.

How are you measuring the fridge on cycle time?

I timed the run time and off duration with the wall clock for a week, compiling a 10 page collection of run times in the process.
It is a high resolution measurement.

Also in the morning when its 15c inside the fridge will stay off for 3 hours and run for 30 min.

The bottom and back are the real problem areas.
I tested the fridge with just the bottom of the fridge from the kick panel to the compressor/condenser insulated for a few days and noted a shorter run duration consistently of 2 - 3 minutes and a 10 -15 minutes longer off time.

Now I'll really really have to do it. Every time I look at my TED data logs I can see the fridge turning on and off all day long...

Haha it was dedication!, I actually tested each layer of insulation and its effect, the on time shortened and the off time lengthened predictably with each layer, i may yet add more layers down the road, but first i want to conduct more tests.

Your TED will be liking the fridge insulation, I also wanted to mention that if you could, insulate the refrigerators top as the freezer section could use the extra insulation.
