OEM Carrier 2-Pole Contactor 40 Amp 24V for Model TCHC2550HECMRSH501

This OEM Carrier contactor (part number HN52TC040) is the factory-specified replacement for the Carrier TCHC2550HECMRSH501 heat pump system. The contactor is the high-voltage relay that bridges 240V line power to the compressor and condenser fan motor each time the thermostat calls for cooling or heating. When the 24V control circuit energizes the coil, the contactor pulls in and closes the high-voltage circuit. A failing contactor is one of the most common causes of a system that hums but won't start, trips a breaker, or simply has no response from the outdoor unit.

  • Specs: 2-pole | 40 FLA (Full Load Amps) | 24V 50/60Hz coil | Definite-purpose contactor | Factory OEM direct fit for TCHC2550HECMRSH501
  • OEM vs Generic: OEM contactors use factory-spec contact material and coil winding, ensuring pull-in voltage thresholds and contact durability match original design. Generic contactors often use lower-grade contact alloys that pit and weld faster under high-cycle heat pump loads.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph existing wiring before disconnecting any leads. The contactor mounts with two screws and wires terminate on labeled screw lugs.
  • Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Engineered as a drop-in OEM replacement for the Carrier TCHC2550HECMRSH501 heat pump. Always verify the pole count, amp rating, and coil voltage on your existing contactor's data label before ordering. Our fitment team is available to confirm compatibility prior to purchase — same-day shipping on all in-stock orders.

Frequently Asked Questions

Does this Contactor fit my Carrier TCHC2550HECMRSH501?
Yes. This is the factory-specified OEM contactor for the Carrier TCHC2550HECMRSH501. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier TCHC2550HECMRSH501?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
