Arrived to remedy an inoperable system. Turned system on and found that it would start up and run as designed. Checked the evaporator coil to ensure that the system is not freezing up. Checked system temperature split. Went outside and checked power consumption of the fan and compressor. Checked system refrigerant levels. All tests are within spec. When checking the capacitor in the condenser found that a wire connection was very loose and could have caused an amperage spike.
