The outside of my refrigerator is hot?

Question

in a few areas

Answer 1

It's supposed to be.  The fridge doesn't just "make cold" - it makes one area cold at the expense of making another area (the outside) hot.

Like your a/c, basically what it does is:

1) Compress some air, which makes that air hot

2) Cool that compressed air back down

3) Uncompress that air, which makes it cold
