OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C48ZN055200

This OEM replacement contactor is the factory-specified part for the Carrier C4850C48ZN055200 packaged unit. The contactor acts as a high-voltage relay, receiving a 24V signal from your thermostat or control board to close its contacts and send line-voltage power to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or mechanical wear — the unit will not respond to a call for cooling, leaving you with a system that hums or does nothing at all despite a working thermostat signal.

  • Specs: 2-pole configuration | 24V control coil | Line voltage contacts rated for compressor and fan motor loads | Direct OEM replacement for part numbers HN53CB115, HN53HF122, and HN53HG120
  • OEM vs Generic: OEM contactors are manufactured to Carrier's exact coil pull-in voltage and contact material specifications. Generic alternatives often use inferior contact alloys that pit and burn faster, causing premature re-failure within a single cooling season.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and verify zero voltage with a multimeter before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter, and insulated wire labels. Photograph all wiring before disconnecting terminals to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. In stock and ships the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier C4850C48ZN055200 packaged unit. Cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Verify coil voltage and pole configuration on your unit's data plate before ordering. Our parts specialists are available to confirm fitment prior to purchase — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C48ZN055200 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C48ZN055200 | 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 C4850C48ZN055200 | 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?
