OEM Carrier 2-Pole Contactor 24V Coil for Model C50A502752

This OEM contactor is the factory-specified replacement for the Carrier C50A502752 packaged unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the stat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioner stops responding: you may hear a click with no compressor startup, notice pitted or fused contacts on inspection, or find the unit completely unresponsive to cooling calls. Replaces OEM part numbers HN53CB115, HN53CD115, HN53HF122, and HN53HG120.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage for compressor and fan load | Direct OEM drop-in replacement with matching terminal layout
  • OEM vs Generic: OEM contactors use silver-alloy contacts rated to exact factory specifications, resisting arcing and pitting over thousands of switching cycles. Generic contactors often use lower-grade contact materials that degrade faster under high inrush current loads.
  • Install difficulty: 2/5 — Disconnect all power at the disconnect box and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil continuity. Always photograph wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier C50A502752 packaged unit, cross-referencing part numbers HN53CB115, HN53CD115, HN53HF122, and HN53HG120. Confirm your unit's data plate voltage and amperage ratings match before installing. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Carrier C50A502752?
Yes. This is the factory-specified OEM contactor for the Carrier C50A502752. 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 C50A502752?
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?
