got a new fridge, learned an energy saving tip from the old one - Page 2

Another thing to watch out for if you want to overinsulate your unit is that many fridges and freezers have a highside tube at the front of the fridge where the door seal is.
If you feel this area you can actually feel the warmth on some units especially sub zeros and jennair (they tend to get hot actually)

I too have thought about adding foam to the fridge because of how cold to the touch the outside feels. FYI I posted a link in another forum here with lab numbers on how much the foam degrades over time. The conductivity goes up quite a bit in the first two years.

Another thing that can be applying the heat to the door seal is a resistive heater. If your fridge draws 10 to 20 watts for no apparent reason it's likely heating the door seals.

I cleaned out and turned off the deep freezer a few months ago.
The warmer weather and no deep freezer running just about cut the power bill in half.
But since its warmer I have been running air compressors almost non stop some times when powering sand blaster and orbital sander.
The thing that cuts the power bill are the deep freeze and little to no needd for a heater. Running air compressors doesnt hurt the power bill very much.
