OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C48ZG070200

This is the factory OEM replacement contactor for the Carrier C4850C48ZG070200 packaged or split-system unit. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to energize the compressor and condenser fan motor. When it fails — due to pitted or burned contacts, coil burnout, or contact welding — your system may hum without starting, fail to cool entirely, or run continuously without shutting off. Replacing the contactor is one of the most common and cost-effective HVAC repairs available. OEM part numbers HN53CB115 and HN53HF122 are both factory-authorized replacements for this model.

  • Specs: 2-Pole configuration | 24V control coil | 30–40A contact rating | Direct OEM replacement for Carrier part numbers HN53CB115 and HN53HF122
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic substitutes frequently use lower-grade alloys that pit and burn faster, leading to premature failure and potential compressor damage.
  • Install Difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is absent with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring connections before removal. Swap wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered specifically for the Carrier C4850C48ZG070200. Cross-references OEM part numbers HN53CB115 and HN53HF122. Always verify pole count, coil voltage, and amperage rating on your unit's data plate before ordering. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C48ZG070200 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C48ZG070200 | 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 C4850C48ZG070200 | 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?
