We have a G.E. 2-door refrigerator that's about 15 years old. It's never
had any problems. Recently, I noticed that the contents were warming up,
and the ice began melting. When I turned the main temperature control
wheel to "off" and then "on", the compressor started up, and it worked fine
for a few days. Today, it warmed up again. I turned it "off" and "on", and
it started working.

Any idea on what's going on?

Thanks!
