OEM Carrier 2-Pole Contactor for Model C4850C50AY05151 Packaged Unit

This OEM contactor is the factory-specified replacement for the Carrier C4850C50AY05151 packaged unit. The contactor is a high-voltage relay controlled by the 24V signal from your thermostat or control board — when energized, it closes the circuit to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system hums, buzzes, or simply won't turn on at all. Burnt or pitted contacts, a stuck armature, or a failed coil are telltale signs this part needs replacement.

  • Specs: 2-Pole configuration | 24V coil voltage | High-amperage contacts rated for compressor load | Direct OEM replacement for part numbers HN53CB115, HN53HF122, and HN53HG120
  • OEM vs Generic: OEM contactors use silver-alloy contact tips engineered to exact factory arc-resistance tolerances. Generic contactors often use inferior contact materials that pit and weld prematurely, leading to repeat failures and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil continuity. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier C4850C50AY05151 4-ton packaged unit. This contactor supersedes and replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120 — all three part numbers are covered by this single listing. Verify coil voltage and pole configuration on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy. Order now and get same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AY05151 — Ships Today?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AY05151 — 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 C4850C50AY05151 — 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.
