Upon arrival for evaluation homeowner had system off because outdoor condenser was not coming on and he didn't want to cause damage He mentioned that he reset indoor breakers and outdoor breakers to unit to see if that would fix it and no change I started my turning unit on and checking indoor unit to see if I had power and fan once I verified that I did I moved to outdoor unit Upon arrival I flipped disconnect and removed service panel Flipped disconnect back up and found that I had an L6 error code which led me to the capacitor I checked capacitor and it was very out of tolerance called dispatch to check warranty and found that homeowners have PnL still so I replaced capacitor under warranty and went to turn unit back on Control board was still showing L6 error code so I verified again that capacitor was good which it was so I went inside and reset unit from air handler. After delay condenser kicked on and system started cooling I checked Delta and had 21° of cooling Left system
