OEM Carrier 2-Pole Contactor 35A 208/240V for Model YAC48140YAC303T

This OEM contactor (part number HN52KC053) is the factory-specified replacement for the Carrier YAC48140YAC303T packaged unit. The contactor is a high-voltage relay that closes when the thermostat calls for cooling, sending line voltage to the compressor and condenser fan motor. When it fails — through pitted contacts, a burned coil, or a stuck-open position — the system will appear completely unresponsive: the compressor and outdoor fan won't start even though the thermostat is calling. You may also notice chattering, humming from the contactor box, or intermittent cooling failure on hot days when electrical demand is highest.

  • Specs: 35 Amps | 2-Pole | 208/240V coil | Factory OEM part number HN52KC053 | Replaces original Essex/Carrier contactor assembly
  • OEM vs Generic: OEM contactors are manufactured to exact Carrier electrical tolerances, with contact surface materials and spring tensions matched to the compressor load profile of the YAC48140YAC303T. Generic contactors often use lower-grade contact alloys that pit faster under repeated switching cycles, shortening service life significantly.
  • Install difficulty: 3/5 — Always disconnect and lock out power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify coil continuity and confirm 24V signal), and a camera or phone to photograph wiring before removal. Capacitor discharge is not required for this repair, but verify all line-voltage terminals are de-energized before touching.
  • Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Designed for the Carrier YAC48140YAC303T packaged unit. Always verify your unit's data plate voltage, amperage, and pole count before ordering to ensure a correct match. Our fitment team is available to confirm compatibility before you purchase — no guesswork required. Order today and get same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Carrier YAC48140YAC303T?
Yes. This is the factory-specified OEM contactor for the Carrier YAC48140YAC303T. 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 YAC48140YAC303T?
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?
