Did a service call last night on an old Trane heatpump. The circuit breaker would trip after the outdoor unit ran for an hour. I checked the temp and pressures everything was in order. But, when I checked the run amps 10.4 A from the nameplate, one leg was was at 10.3 the other was at 6.4 A. The unit is 240V/1 phase.
Being it was getting close to 11 PM I couldn't stay to see the breaker trip. I believe the compressor is on its last leg. Is this correct?
