General Assist Parts Reference

Parts Not Listed in the System

Legacy R22 and R410A air-conditioning systems
Reference list for low-volume legacy parts, including wiring looms, step motors, thermistors, PCBs and other components that may not appear in the normal ordering system.
Quick answer: A part not appearing in the ordering system may still be identifiable or available. Search this article by part number or model number, then contact Spare Parts to confirm current availability, price, supersession and lead time before committing to a customer.
Important: This is a legacy reference list, not confirmation of stock. Many listed components relate to older R22 or early R410A products and are not ordered regularly. Some may be discontinued, superseded or available only by special order.

How to request a listed part

1Confirm the complete indoor or outdoor model number from the unit rating label.
2Search the table below using the model number, part number or component description.
3Provide Spare Parts with the model, serial number, required component and any part number located.
4Wait for confirmation of availability, supersession, price and lead time before placing or promising an order.

Interpretation and ordering notes

  • Model references have been reproduced from historical working records and may include abbreviated, grouped or alternate model formatting.
  • A model appearing beside a part indicates a recorded association only. Always validate compatibility against the serial number, exploded parts list or advice from Spare Parts.
  • Where the part number is shown as Not listed, the source record contains a description but no confirmed orderable part number.
  • Special-order electrical components such as wiring looms, thermistors and PCBs may have extended lead times and may not be returnable.
  • Refrigerant type does not by itself confirm component compatibility. Use the full equipment model and serial number.
Do not substitute parts based only on appearance. Electrical ratings, connector arrangements, sensor characteristics and PCB programming can differ between visually similar components.
