Mark,
Quit referring to CJ great and best reputation from others and worry about yourself only to be fair.
If you want response FAST call SALES department first like you want to purchase a new unit than start asking tough questions to whoever picks up the phone. I always know that it’s BEST shortcut to get to the conversation. You can even start asking technical details of the unit that you want to get instead of your FUBAR and if sales person doesn’t find an answer, one will connect you to either specialist or the owner himself.
...and yes, labor to replace large power capacitor should not be over $100. so part is $50 + labor $100 (a-bit over an hour job) should be $150 and not $579.xx
