OEM Carrier Contactor 2-Pole 24V Coil for Model TCHC2550HECMRAY102

This is the OEM factory-specified contactor for the Carrier TCHC2550HECMRAY102 system, sold under OEM part number HN52TC040. The contactor is the high-voltage switching relay that connects utility power to the compressor and condenser fan motor every time a cooling call is made. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — the result is an outdoor unit that refuses to energize, hums without starting, or runs continuously even with no thermostat call.

  • Specs: 2-pole configuration | 24V control coil | Factory-rated ampacity to match compressor load on TCHC2550HECMRAY102 | Direct OEM drop-in replacement for HN52TC040
  • OEM vs Generic: This OEM contactor uses silver-alloy contact tips rated to Carrier's exact factory specification. Aftermarket units often use lower-grade contacts that arc and pit faster under high-inrush compressor loads, leading to premature failure and potential compressor damage.
  • Install Difficulty: 3/5 — Work must be performed with the disconnect pulled and capacitor discharged. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Always photograph all wiring connections before removal. Verify coil voltage at the thermostat terminals before condemning the contactor.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day when ordered before cutoff.

Compatibility: Engineered specifically for the Carrier TCHC2550HECMRAY102. Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering to ensure proper fit. Our fitment team is available to confirm compatibility before you buy — no guesswork required. Order today and get back up and running fast with same-day shipping from NationalHVACParts.com.

Frequently Asked Questions

Does this Contactor fit my Carrier TCHC2550HECMRAY102?
Yes. This is the factory-specified OEM contactor for the Carrier TCHC2550HECMRAY102. 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 TCHC2550HECMRAY102?
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?
