Insulating compressor housing
Next mod was to add a heat shield insulation above the compressor. It's directly under the warm shelf area in the fridge. When the compressor turns off and condenser reaches room temp the large metal compressor stays hot. This heat goes straight up to the bottom of the shelf.
Not real scientific but in an air conditioned house the compressor ran at 115F and cools to only 104F after 25 minutes. All that time between cycles that heat is migrating into the fridge. The compressor is a big chunk of metal so it is what it is. It cools slow.
I finally found the rattle that this thing has had since I pulled it new out of the box. A rouge screew was inside the compressor housing. Everthing was tight and well made so no worry.
Next I basically cut foam and covered it with reflective copper tape to keep the heat off of the shelf inside the fridge.
I used what I had on hand. Above the compressor is a perfect 1/2" high recess that is the floor of the shelf. The foam flooring I had fit well.
Basic shape of the foam when cut to fit.
The only glue I had that was not dried up in this Arizona heat was 3M 5200. It fit so nice with compression and the fridge parts holding it up I'm not even sure it needed the glue. I covered it with the copper tape as a radiant reflector. And stuck it up. The last picture in my airflow post shows how well it fit.
A small 3" piece fit above the electronic box on the other side of the compressor to finish it up.
There are a few straight forward screews you can loosen to gain a little more clearance. They are on the brackets and bottom of the fridge. Loosening makes fitting the insulation a little easier. I could not find any thing that was cold to the touch in the compressor housing that needed insulation or anything else that was not perfect. It's great stock but I feel sorry for the abuse I give it in this Arizona heat and hope I helped it out.
