Performed AC diagnostic on two year old Goodman system. Upon my diagnostic client stated that system is not able to drop temperature throughout the day and was able to get to 67° in the past and now it doesn’t get below 75. Found at the outdoor condensing unit to do a secondary motor control has become Defective on the hermetic side terminal which means the compressor wasn’t on. Installed new duel secondary motor control system is cooling with a 15° split differentials and refrigerant pressures look good at this moment. Part was covered under warranty and upon departure system is fully operational and cooling.
