As I mentioned in my introduction, I consider myself a meatball surgeon who wants to go from "Just keep 'em running" to a more service tech line of thought i.e. fix the problem not just patch it.
Yes I'm Type 3 certified and, yes I've been doing this for going on 10 years but, in the end, my real servicing experience would probably make a first year journeyman giggle. The property I learned on was over 15 years old so, when a unit died, the rule was simply replace it with a new one, then scrap out the old. I did over 40 change outs on that property in that manner.
The problem is that now I'm on a relatively new property and have been here almost 7 years. Service has been pretty much limited to capacitors, fan boards, the occasional leaking coil and a squirt of R22 here and there. I've changed out 5 units here, primarily from hurricane damage. My hardest challenge was finding the shorts that would blow the 5 amp fuses on my Carrier fan boards (wires rubbing inside the condenser would wear thru, shorting against the cabinet).
I now face my first possible compressor failure, something I've never learned to diagnose before. Because the units are around 8-9 years old, I don't want to unjustly send it to an early grave without properly evaluating whether the compressor is truly dead. Could someone walk me through the basics? I'd really appreciate it.
