OEM Carrier 2-Pole Contactor 24V Coil 30A for Model C48A306052

This is the factory OEM replacement contactor for the Carrier C48A306052 packaged unit. The contactor is the high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will appear completely unresponsive: the thermostat calls for cooling, but nothing happens. In other cases, a welded contactor causes the unit to run continuously even when cooling is not demanded. Replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120.

  • Specs: 2-pole | 30A load rating | 24V AC coil | Factory-matched contact material and plunger travel for reliable pull-in and release
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for tens of thousands of cycles. Generic contactors frequently use lower-grade alloys that pit and weld prematurely, leading to repeat failures within one or two seasons.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and verify with a non-contact voltage tester before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring connections before removal. Line-voltage terminals remain energized from the disconnect — confirm both legs are dead before touching.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier C48A306052 packaged unit. This contactor directly replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Verify pole count, coil voltage, and amperage rating on your existing contactor's label before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required. Order before 3 PM EST for same-day shipping.

Frequently Asked Questions

Does this Contactor fit my Carrier C48A306052 (HN53CB115) | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C48A306052 (HN53CB115) | National HVAC Parts. 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 C48A306052 (HN53CB115) | National HVAC Parts?
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?
