    The troubleshooting exercise everyone said was difficult turned out to be...a bad run capacitor to the condensing fan on a four door reach-in freezer. The condensing unit clearly had power to it, and it tripped on high head pressure due to the fan not running (heat not removed from condenser). Just by looking at it, I could tell that the problem had to be a bad fan motor or run capacitor. A microfarad reading with my multimeter quickly proved the run capacitor was bad. I solved this "hard" example in a matter of minutes. People need to remember the basics!

        @metaltao The HVAC education is proving to be most valuable. :) my instructor has noted that being quick at some of this stuff indicates we are getting good at doing this. Hopefully this will give me an edge when it comes to next month's job interview.

      @m14brony The basics are pretty darn Fundamental, Good you remembered them!

        @metaltao Indeed. I was a bit disappointed when this exercise didn't turn out to be as challenging as I anticipated. Nonetheless, it does show the importance of the basics: one can sometimes narrow things down rather well just by observing HVAC equipment instead of immediately digging into one's toolbox.
