Performed Ac maintenance on 6 year old Carrier system. Cycled system for cooling. Pulled condenser fan motor and thoroughly washed out condenser coil inside and out with coil cleaner and water. Checked system electrical and components. Amp draws for compressor are within range. Condenser fan motor is close to over amping and has started to leak oil. Secondary motor control is out of range for condenser fan motor, which explains why amp draws are high and motor is leaking. Refrigerant levels are in range and system is producing proper temperature split. Went over findings and recommendations with homeowner. With approval went ahead and replaced secondary motor control. Homeowner had coupon for discounted maintenance promo. Cycled system, system is operational upon departure.
