OEM Carrier 3-Pole Contactor 40A for Model YAC48110YAC104AC (HN53CD024 / HN53CD208)

This OEM Carrier 3-pole contactor is the factory-specified replacement for the Carrier YAC48110YAC104AC packaged unit. The contactor acts as a high-voltage relay, receiving a 24V or 208–240V signal from the control board to close its contacts and energize the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck/welded plunger — the system will either refuse to start entirely, run continuously without cycling off, or trip the breaker. This listing covers both OEM part numbers: HN53CD024 (24V coil) and HN53CD208 (208–240V coil). Verify your unit's control voltage on the wiring diagram or data plate before ordering.

• Specs: 3-Pole | 40A FLA / 160–240A LRA | Screw terminal connections | Coil options: 24V DC (HN53CD024) or 208–240V AC 50/60 Hz (HN53CD208) | Max switching voltage: 600V
• OEM vs Generic: OEM contactors use factory-spec copper alloy contacts rated for the exact load profile of your Carrier YAC48110YAC104AC. Generic contactors often use lower-grade contact materials that pit faster under inductive compressor loads, leading to premature failure and potential compressor damage.
• Install difficulty: 3/5 — Power must be fully disconnected at both the disconnect box and breaker panel before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify coil continuity and contact resistance), and a voltage tester. Always photograph all wiring before disconnecting. Verify coil voltage matches your unit before installation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered by cutoff time.

Compatibility: Designed for the Carrier YAC48110YAC104AC packaged unit. This contactor is also cross-referenced to Bryant and related ICP family units sharing the same electrical specifications. Double-check coil voltage (24V vs. 208–240V) against your system's wiring diagram before selecting the correct part number. Questions about fitment? Our team verifies compatibility before you order — ships same day.
