OEM Carrier 3-Pole Contactor 25A 115V for Model 09DK024500

This is the genuine OEM factory-specified 3-pole contactor for the Carrier 09DK024500 commercial HVAC unit. The contactor is a high-voltage relay that closes the circuit between the 115V power supply and the compressor and fan loads whenever the control board sends a 24V signal. When this component fails, the unit will not respond to a thermostat call for cooling — you may hear a click at the thermostat or control board with no compressor or fan startup, or experience intermittent operation due to worn or pitted contact points.

• Specs: 3-Pole | 25 Amp FLA | 115V AC Coil | Replaces OEM part numbers HN53TB115, HN52KC016, HN72AZ301 | Compatible Hartland Controls model HCCY3XT01DT103
• OEM vs Generic: This is a genuine Carrier factory part (HN53CB115) engineered to exact contact gap, spring tension, and coil pull-in voltage specifications. Aftermarket contactors may use lower-grade contact alloys that pit and arc faster — shortening compressor life and causing nuisance lockouts.
• Install Difficulty: 3/5 — Requires disconnecting line-voltage power at the disconnect box before service. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, voltage tester, camera or phone to document wiring. Always verify power is OFF before touching terminals. Label all wires before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
