Amana PTH123G35AXXXAA: 12,000 BTU Packaged Terminal Heat Pump PTAC Service
The Amana PTH123G35AXXXAA is a packaged terminal heat pump air conditioner combining cooling, heat pump heating, and 3.5 kW electric heat strip backup in a self-contained chassis. The PTH designation distinguishes this heat pump model from PTC electric-heat-only PTAC configurations. Annual filter cleaning every two weeks during heavy use prevents the airflow restriction that leads to evaporator coil icing and reduced heating and cooling capacity.
Most Replaced Parts on the Amana PTH123G35AXXXAA
Run Capacitor for the Amana PTH123G35AXXXAA
A failed run capacitor prevents the compressor from starting. Test the capacitor with a digital capacitance meter before ordering any other component.
Control Board for the PTH123G35AXXXAA
A board fault typically presents as the unit not responding to the thermostat, running continuously, or displaying fault codes. Read any displayed error codes before ordering a replacement.
Thermistor for the Amana PTH123G35AXXXAA
The thermistor provides the indoor temperature reading used by the control board to cycle the compressor. A failed thermistor causes the unit to overheat or undercool the room.
Fan Motor for the PTH123G35AXXXAA
The fan motor circulates indoor air across the evaporator coil and outdoor air across the condenser coil. Test the run capacitor before ordering a replacement motor.

The Amana PTH123G35AXXXAA is a 12,000 BTU Packaged Terminal Air Conditioner and Heat Pump unit from Amana. PTAC units are self-contained heating and cooling systems installed through exterior walls, commonly found in hotels, apartments, and multi-unit residential buildings.
What does the PTH designation mean on the Amana PTH123G35AXXXAA?
The PTH designation identifies this as a heat pump PTAC unit, capable of both cooling and heating. The 12 identifies approximately 12,000 BTU cooling capacity, 3G identifies the chassis generation, and 35A identifies the 3.5 kW electric heat strip backup.
Why is my Amana PTH123G35AXXXAA not heating or cooling?
A PTAC unit not heating or cooling is most commonly caused by a failed run capacitor preventing the compressor from starting, a failed control board not completing the heating or cooling cycle, or a thermistor providing an incorrect temperature reading. Test the capacitor before ordering a control board.
How often should I clean the filter on the Amana PTH123G35AXXXAA?
Clean the washable filter every two weeks during heavy use. A clogged filter restricts airflow across the evaporator coil and can cause the coil to ice over, reducing both heating and cooling capacity.
