OEM Carrier 2-Pole 40 Amp 24V Contactor (HN52TC040) for Model TCHC2550HECMRAY103

This is the genuine OEM replacement contactor for the Carrier TCHC2550HECMRAY103 heat pump system. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes the circuit to supply line voltage to the compressor and condenser fan motor. When the contactor fails, you'll typically see the outdoor unit fail to energize entirely, hear a chattering or humming at the contactor, or notice pitted and burned contacts from repeated arcing — all resulting in a no-cool or no-heat condition.

  • Specs: 2-Pole | 40A FLA (Full Load Amps) | 24V 50/60Hz Coil | 240/277V Load Voltage | OEM Part Number: HN52TC040
  • OEM vs Generic: This is a genuine Carrier OEM contactor with factory-spec coil resistance and contact ratings. Generic contactors often use lower-grade silver-alloy contacts that pit and fail faster under the high-inrush current of compressor startup.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier TCHC2550HECMRAY103 heat pump system. Verify your existing contactor's pole count, amp rating, and coil voltage against your unit's data plate before ordering. Have a fitment question?

Frequently Asked Questions

Does this Contactor fit my Carrier TCHC2550HECMRAY103?
Yes. This is the factory-specified OEM contactor for the Carrier TCHC2550HECMRAY103. 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 TCHC2550HECMRAY103?
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?
