I'm guessing, with no real knowledge, that the compressor went. There
was a burning smell, the fuse blew, and when I ran an extension to the

at the bottom. So, I'm guessing compressor. Is that likely?

If so, a new compressor is around $180, much cheaper than a new
refrig. The parts guy (Sears) says that anyone can replace the
compressor, that I can get a do-it-yourself guide for $15.

A new model would be around $600 and a big pain. Is replacing a
compressor so hard?

The choice is not exclusively between a (modest) $600 fridge and a $150
repair.

Check Craigslist for used fridges. Often they are free.
