OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50Z3070100

This OEM replacement contactor is the factory-specified part for the Carrier C4850C50Z3070100 packaged unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the thermostat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't turn on, hums continuously without starting, or shows visible pitting and burning on the contact points. OEM part numbers HN53CB115 and HN53HF122 are both factory-authorized replacements for this unit.

  • Specs: 2-Pole configuration | 24V coil voltage | Factory-rated amp capacity | Direct OEM replacement for Carrier part numbers HN53CB115 and HN53HF122
  • OEM vs Generic: OEM contactors use silver-alloy contact points rated for the exact load demands of your Carrier unit. Generic contactors often use lower-grade contacts that arc and pit faster, shortening compressor life and increasing failure frequency.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and verify voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before 3PM EST ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier C4850C50Z3070100 packaged unit. Cross-references OEM part numbers HN53CB115 and HN53HF122. Always confirm coil voltage and pole configuration on your unit's data plate before ordering. Our fitment team is available to verify compatibility prior to purchase — reach out before you order if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50Z3070100 — Ships Today?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50Z3070100 — Ships Today. 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 C4850C50Z3070100 — 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.
