OEM Carrier 2-Pole Contactor 40 Amp 24V Coil for Model TCHC2550HECMRAY602

This OEM contactor (part #HN52TC040) is the factory-specified high-voltage relay for the Carrier TCHC2550HECMRAY602 system. The contactor acts as the primary electrical switch that closes the high-voltage circuit to your compressor and condenser fan motor every time the thermostat calls for cooling. When the contactor fails, you'll typically find the outdoor unit completely unresponsive — the system won't turn on at all, or it may hum under load with no mechanical response. Burned or pitted contacts, a coil that won't pull in on 24V, and premature compressor cutout are all classic signs this part needs replacement.

  • Specs: 2-Pole | 40 FLA (Full Load Amps) | 24V 50/60Hz coil | 240/277V load side | Factory OEM part #HN52TC040
  • OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory specifications. Generic contactors often use lower-grade contact materials that pit and erode faster under repeated switching, leading to premature failure and compressor damage.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire connections before removal. Discharge any residual capacitor voltage nearby before touching terminals.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for Carrier model TCHC2550HECMRAY602. Always verify your unit's data plate amperage and coil voltage match 40A / 24V before ordering. Our fitment team is available to confirm compatibility before you buy — order with confidence and get your system back up fast.

Frequently Asked Questions

Does this Contactor fit my Carrier TCHC2550HECMRAY602?
Yes. This is the factory-specified OEM contactor for the Carrier TCHC2550HECMRAY602. 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 TCHC2550HECMRAY602?
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?
