OEM Carrier 3-Pole Contactor 25A 115V Coil — HN53CB115 for Model 09DK094600

The Carrier HN53CB115 is the factory-specified OEM 3-pole contactor for the Carrier 09DK094600 commercial HVAC unit. The contactor is the high-voltage switching relay that energizes the compressor and associated load circuits when the control board sends a 24V signal. A failing contactor is one of the most common causes of compressor lockout — symptoms include the system not responding to a call for cooling, burned or pitted contacts causing arcing noise, or the unit cycling on and off erratically without reaching setpoint.

• Specs: 3-Pole | 25A FLA / 35A RES | 115V (120VAC) Coil Voltage | Factory OEM replacement for Carrier part number HN53CB115 | Cross-references: HN53TB115, HN52KC016, HN72AZ301
• OEM vs Generic: This is a genuine Carrier OEM contactor manufactured to exact factory contact-gap, coil-pull-in, and temperature-rise specifications. Aftermarket contactors often use lower-grade silver-alloy contacts that pit and weld faster under compressor inrush current, shortening service life significantly.
• Install Difficulty: 3/5 — Requires disconnecting high-voltage power at the disconnect box and verifying zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wiring connections before removal. Label each wire to its terminal for accurate reinstallation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
