This document provides repair parts information for the Amana PTH093G Series PTAC Heat Pump and the PTH094G Series PTAC Heat Pump. These are Packaged Terminal Air Conditioners (PTACs) designed for heating and cooling applications, commonly found in hotels, motels, and other commercial or residential settings requiring individual room climate control.

Function Description

The Amana PTAC Heat Pumps are self-contained heating and cooling units that offer year-round comfort. They operate as heat pumps, meaning they can reverse the refrigeration cycle to provide both heating and cooling. In cooling mode, the unit extracts heat from the indoor air and expels it outdoors. In heating mode, it extracts heat from the outdoor air (even in cold conditions) and transfers it indoors. This heat pump technology makes them energy-efficient compared to electric resistance heating alone. The units also include supplemental electric resistance heaters for periods when the outdoor temperature is too low for efficient heat pump operation or when rapid heating is desired.

Key functional components include:

Compressor: The heart of the refrigeration cycle, responsible for circulating refrigerant and compressing it to raise its temperature and pressure. The PTH093G series uses a RECHI compressor (44A202AS), while the PTH094G series also uses a RECHI compressor (44A202A).
Reversing Valve: Allows the unit to switch between heating and cooling modes by changing the direction of refrigerant flow. Both series utilize a 230V reversing valve assembly (0151P00000 for PTH093G, 0151P00001 for PTH094G).
Indoor and Outdoor Fan Motors: Circulate air across the indoor and outdoor coils to facilitate heat exchange. The PTH093G series uses 0131P00029s for indoor and 0131P00027s/0131P00033s for outdoor. The PTH094G series uses 0131P00028s for indoor and 0131P00030s/0131P00031s for outdoor.
Coils (Evaporator and Condenser): These are heat exchangers where the refrigerant absorbs or releases heat. The "Tubing Assy" diagrams show the evaporator and condenser coils as integral parts of the refrigeration circuit.
Control Board: Manages the operation of the unit, including fan speeds, compressor cycles, and temperature settings. Both series use a M61 control board (RSKP0010).
Thermistors: Temperature sensors used by the control board to monitor air and coil temperatures for precise control and protection. Various thermistors are listed, including discharge, indoor coil, and clip-type thermistors (e.g., 0130P00075, 0130P00086, 0130P00093 for PTH093G; 0130P00098, 0130P00086, 0130P00093 for PTH094G).
Electric Heaters: Supplemental heating elements (e.g., 0275P00019, 0275P00020S, 0275P00021S for PTH093G; 0275P00023, 0275P00040, 0275P00041 for PTH094G).
Capacitor: Stores electrical energy and provides a starting boost for the compressor and fan motors. Both series use a CAP, 2/25 MFD/450V/DUAL RD (CAP020250450RSS for PTH093G; CAP020250450RS for PTH094G).

Important Technical Specifications

The model numbers indicate various technical specifications, primarily related to heating and cooling capacity, voltage, and specific features. The "093G" and "094G" in the model numbers likely refer to the nominal cooling capacity in BTUs per hour (e.g., 9,000 BTU/hr). The subsequent characters denote voltage, amperage, and other configurations.

Voltage and Amperage: The units are designed for various electrical configurations, indicated by the model nomenclature. For instance, the cord specifications show different amperage ratings (15A, 20A, 30A) and voltage (250VAC) for the PTH093G series, and 277 VAC for the PTH094G series, suggesting different electrical requirements based on the specific model. Transformers (e.g., 0130M00149, 0130M00150 for PTH093G; 0130M00151, 0130M00152 for PTH094G) are used to step down voltage for control circuits.

Refrigerant: The PTH094G series explicitly states "This system uses R410A refrigerant." While not explicitly stated for PTH093G in the provided pages, it is highly probable that it also uses R410A, a common refrigerant in modern PTAC units due to its ozone-friendly properties.

Control System: Both series feature a control board (RSKP0010) and a variable speed terminal board (PCBEP100s), indicating advanced control capabilities for fan speed and overall unit operation.

Usage Features

Amana PTAC heat pumps are designed for user convenience and flexibility in various settings.

Individual Room Control: Each unit provides independent temperature control for a single room, allowing occupants to set their preferred climate without affecting other areas.
Heating and Cooling: The heat pump functionality provides both heating and cooling from a single unit, eliminating the need for separate systems. Supplemental electric heat ensures comfort even in colder climates.
User Interface: The "Front Assy" and "Partition Assy" diagrams show the control panel cover (RSKP0005) and a ribbon extension (131), suggesting a user-friendly interface for setting temperature, fan speed, and operating mode.
Quiet Operation: While not explicitly detailed in the parts list, PTAC units are generally designed with noise reduction in mind, especially for hospitality applications. Components like fan motors and compressor mounts contribute to this.
Easy Installation: PTAC units are designed for through-the-wall installation, making them relatively straightforward to integrate into building structures.

Maintenance Features

The provided repair parts manual is a critical resource for maintenance and service.

Modular Design: The breakdown of components into assemblies (Front Assy, Chassis Control Panel, Partition Assy, Indoor Assy, Tubing Assy) indicates a modular design, which simplifies troubleshooting and part replacement.
Accessible Components: The diagrams show that many components, such as the control board, fan motors, and coils, are accessible for inspection and replacement.
Detailed Parts List: Each component is listed with a part number and description, making it easy to identify and order the correct replacement parts. This is crucial for efficient repairs and minimizing downtime.
Troubleshooting Support: While not a troubleshooting guide itself, the detailed parts list, combined with the "Important Information" section, guides qualified technicians in identifying faulty components.
Qualified Technicians: The manual explicitly states, "This manual is to be used by qualified technicians only," and "Warranty service must be performed by an authorized technician, using authorized factory parts." This emphasizes the importance of professional service for safety, proper operation, and warranty validity.
Regular Cleaning: Although not explicitly listed as a part, regular cleaning of air filters and coils is a standard maintenance practice for PTAC units to ensure optimal performance and air quality. The "Front-Discharge Louvers" (0161P00033) and "Filter, Rack (QTY 2)" (0161P00035 for PTH093G; 0161P00035 for PTH094G) suggest the presence of air filtration.
Warranty Information: The "Important Information" section outlines warranty service requirements, emphasizing the use of authorized technicians and factory parts. It also notes that Goodman Company, L.P. is not responsible for personal injury or property damage resulting from improper service.

In summary, the Amana PTH093G and PTH094G Series PTAC Heat Pumps are versatile, self-contained units designed for efficient heating and cooling in individual rooms. Their modular construction and detailed parts documentation facilitate professional maintenance and repair, ensuring long-term performance and comfort.
