Okay, before I divulge protected trade secrets for fixing refrigerators, I have to ask for your solemn vow of silence. Divulging this information to the profane can get me in big trouble with my Brethren in The Craft. I could get thrown out of the International Appliance Repair Guild! So, please, if you feel like sharing these secrets with someone, do so by forwarding them this entire newletter. That way, nothing can get taken out of context that might get me trouble with The Brethren. Domo!

2. Burned out compressor start relay (very fixable)
3. Bad or lazy condenser fan motor (very fixable)
4. Bad compressor or sealed system ("freon") leak (terminal event: go shopping)
As indicated, the first three causes are very fixable, even preventable. But the fourth one is a 4th Down Time to Punt event. That's because EPA's DuPont regulations have made doing sealed system work so expensive that it's not cost-effective to do it on most refrigerators... unless you paid so much for the box that you're married to it (a la Sub-Zero). So, lots of easily-repairable refrigerators choking up the landfills today.
Be that as it may, let's talk about the first three things that we can do something about...
