OEM Carrier 2-Pole Contactor for Model C48A306011 Packaged Unit

This OEM replacement contactor is the factory-specified part for the Carrier C48A306011 packaged unit. The contactor is a high-voltage relay that connects and disconnects power to the compressor and condenser fan motor when signaled by the 24V control circuit from your thermostat. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will either fail to turn on entirely, run continuously without shutting off, or trip the breaker repeatedly. Replacing a worn contactor is one of the most common and cost-effective AC repairs available.

  • Specs: 2-Pole configuration | 24V coil voltage | Replaces OEM part numbers HN53CB115 and HN53HF122 | Factory-matched contact ratings for compressor load
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contact tips rated for the exact amperage draw of the C48A306011 compressor. Generic contactors often use lower-grade contacts that pit faster under high inrush current, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Disconnect all power at the breaker and verify with a multimeter before beginning. Tools needed: 1/4" and 5/16" nut drivers, flathead screwdriver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed by 3PM ship same business day from our stocked warehouse.

Compatibility: Designed for the Carrier C48A306011 packaged unit. This contactor replaces both OEM part numbers HN53CB115 and HN53HF122 — verify your existing part number against either before ordering. If you are unsure of fitment, our team is available to confirm compatibility before you purchase. In-stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier C48A306011 — Ships Today?

How do I replace the contactor on my Carrier C48A306011 — Ships Today?
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.
