OEM Carrier 3-Pole Contactor 25A 115V (HN53CB115) for Model 09DK074600

This is the genuine OEM factory-specified 3-pole contactor for the Carrier 09DK074600 commercial HVAC unit. The contactor acts as the high-voltage switching relay that closes the circuit to energize the compressor and condenser fan motor when the 24V control board sends a call for cooling. When this contactor fails — due to pitted contacts, a burnt coil, or welded poles — the system will fail to start, experience intermittent lockouts, or run continuously without shutting off. Replacing it with the correct OEM part restores factory-matched electrical performance and protects downstream components from voltage irregularities caused by worn generic contactors.

• Specs: 3-Pole | 25A FLA / 35A RES | 115V (120VAC) Coil | Definite Purpose Contactor | Factory OEM Part Number HN53CB115
• OEM vs Generic: This genuine Carrier OEM contactor is manufactured to exact contact-gap, coil-pull-in, and heat-dissipation tolerances. Generic contactors frequently use inferior contact alloys that arc and pit prematurely, shortening compressor life and causing nuisance lockouts.
• Install Difficulty: 3/5 — Requires disconnecting main power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter for coil continuity verification. Always photograph all wiring connections before removal. Confirm coil voltage on the unit data plate matches 115V before ordering.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
