OEM Carrier 3-Pole Contactor 24V 40A for Model YAC48110YAC204AC

This OEM 3-pole contactor is the factory-specified replacement for the Carrier YAC48110YAC204AC packaged HVAC unit. The contactor acts as the high-voltage relay that closes when the thermostat calls for cooling or heating, sending 240V power to the compressor and fan motors. When the contactor fails — due to pitted contacts, a burned coil, or contact welding — the unit will fail to energize, hum without starting, or refuse to shut off. Replacing a worn contactor is one of the most impactful and cost-effective repairs you can make on a packaged unit.

  • Specs: 24V AC coil | 3-pole configuration | 40A rated | Max 600V load side | Screw-mount terminal design | OEM Part Numbers: HN53CD024 (primary) / HN53HF212 (alternate)
  • OEM vs Generic: This is a genuine Carrier factory-authorized contactor manufactured to exact contact gap and coil pull-in tolerances. Aftermarket contactors frequently use lower-grade silver alloy contacts that pit faster under high cycling loads, leading to premature repeat failures.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify voltage is absent with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, camera or phone to photograph existing wiring before removal. Transfer one wire at a time to avoid miswiring.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Direct OEM replacement for Carrier model YAC48110YAC204AC. Cross-references OEM part numbers HN53CD024 and HN53HF212. Verify pole count (3-pole), coil voltage (24V), and amperage (40A) on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you order — contact us any time.

Frequently Asked Questions

Does this Contactor fit my Carrier YAC48110YAC204AC?
Yes. This is the factory-specified OEM contactor for the Carrier YAC48110YAC204AC. 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 YAC48110YAC204AC?
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?
