When an HVAC refrigeration system stops cooling, the compressor is often the first suspect. But the right fix might not be a full compressor at all. It could be a wiring harness, a used tested compressor, or an auxiliary unit with cosmetic damage. The choices here range from a $19.99 harness to a $375 auxiliary compressor, so knowing what each part is and what condition it's in matters before you buy.
Quick Take
For a complete compressor replacement with a known model number and tested status, the two Emerson Copeland scroll compressors are the core options. The ZP40K7E-PFV-130 is listed at $280 and the ZP24K6E-PFV-130 at $240, both used, 208/230 V, 1-phase, and black. If you only need the electrical connection, the Copeland wiring harness at $19.99 is an inexpensive component-level buy. The Freightliner auxiliary compressor sits at the top of the price range at $375 and is described as new other with cosmetic damage from handling and storage.

Product Notes
Freightliner Auxiliary HVAC Compressor Sierra01-0716Y3
This is the only auxiliary compressor in the group and the most expensive at USD 375.00. It is in new other condition, has never been used, and shows cosmetic damage to the plastic module plus oxidation and paint blemishes from handling. Choose it if you need a Freightliner auxiliary compressor and can accept cosmetic imperfections. The limitation is that it is not a pristine new unit and the listed manufacturer part number is none, so fit confirmation depends on the Sierra01-0716Y3 reference.
Copeland Molded Plug Wiring Harness 529-0243-02 HVAC Compressor Part
If the compressor itself is fine and you only need the electrical hookup, this harness is the low-cost option at USD 19.99. It is a Copeland molded plug wiring harness, model 529-0243-02, in new open box condition, multicolor, with unit quantity 1. Choose it for a component-level repair where the model number matches your setup. The limitation is that it is not a compressor, so it only solves a wiring problem, not a cooling or pressure problem.
Emerson Copeland / ZP40K7E-PFV-130 / HVAC Compressor / Tested
This used Copeland scroll compressor is listed at USD 280.00 and carries the model ZP40K7E-PFV-130. It is marked as tested, with black color, 208/230 V, 1 phase, and country of origin United States. Choose it if you need a mid-priced tested compressor with the model number and electrical specs stated. The limitation is that it is used, so the running history is a reasonable consideration when comparing it against a brand-new unit.
Emerson Copeland / ZP24K6E-PFV-130 / HVAC Compressor / Tested
At USD 240.00, this is the lower-priced of the two tested Emerson Copeland compressors. It shares the same scroll type, black color, 208/230 V, 1 phase, and used condition as its larger sibling, and is also marked as tested. Choose it if you want the tested-used route and the ZP24K6E-PFV-130 model suits your system. The limitation is that it is used, so it carries the same pre-owned considerations as the other tested unit.
Final Recommendation by Use Case
For an auxiliary compressor with new-other cosmetics, the Freightliner Sierra01-0716Y3 is the only auxiliary unit here, and its $375 price reflects that positioning. For a complete compressor replacement with a known model reference and tested status, the Emerson Copeland ZP40K7E-PFV-130 or ZP24K6E-PFV-130 offer two price points at $280 and $240. If your repair is specifically about the electrical connection, the Copeland wiring harness at $19.99 is the economical component choice.
The clearest split is between buying a whole compressor and buying a part. If you need to restore a full compressor system, the tested Emerson Copeland units give you the model and electrical data to match against your setup. If you already have the compressor and just need the wiring, the harness is the low-cost route. And if you want a Freightliner-specific auxiliary compressor and don't mind visible storage blemishes, the Sierra01-0716Y3 is the one to consider.
