OEM Carrier 2-Pole Contactor 24V Coil for Model C48A303552

This OEM contactor is the factory-specified replacement for the Carrier C48A303552 packaged unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the call for cooling comes in, the contactor closes to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioner won't turn on, hums without starting, or trips a breaker repeatedly. Compatible OEM part numbers include HN53CB115, HN53HF122, and HN53HG120.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage for Carrier C48A303552 | Direct OEM replacement with plug-and-play terminal layout
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic contactors frequently use inferior contact materials that pit and burn faster under high-amperage load, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always shut off power at both the disconnect box and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our climate-controlled warehouse.

Compatibility: Fits Carrier model C48A303552 packaged unit. Cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Always verify pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our fitment team is available to confirm compatibility prior to purchase — same-day shipping available on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Carrier C48A303552 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C48A303552 | 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 C48A303552 | 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?
