I have an older fridge that's no longer getting cold enough. The
temperature of the freezer is about 38 or so. Haven't checked the
actual temp of the fridge section but I doubt it's where it needs to be
either. It seems like it's running constantly. There's a fan in back
that is working. Is it the compressor? Any idea if this is worth
fixing?

The only brand name is "JCPenney" and judging by the harvest gold color
I'd say this was made in the 80's sometime.

Thoughts?
