2013 Goodman heat pump system w/ 16x25x1 filter. Arrived to find main breaker tripped for the outdoor a/c unit. After a few attempts the breaker cooperated, however when asking the system for cooling, the compressor does not engage, neither does blower motor, and only the outdoor fan motor comes on. During visit I got proper voltage into/out of contactor and no issue with capacitor. Customer to be scheduled for a return tech visit to dive further for diagnosis. Customer watches home for homeowners, but system is barely ran and nobody to have been in the home to note when the problem started occurring.
