OEM Carrier 3-Pole Contactor 25A 115V for Model 09DK094500

This genuine OEM Carrier contactor (part number HN53CB115) is the factory-specified replacement for the Carrier 09DK094500 commercial HVAC system. The contactor is a heavy-duty, high-voltage relay that energizes the compressor and fan motor circuits when the 115V control signal is received from the control board. When a contactor fails, symptoms include the system failing to start, a loud chattering or buzzing noise from the electrical panel, burned or pitted contact surfaces, or a tripped breaker caused by high-resistance arcing across worn contacts. Replacing a failed contactor promptly prevents cascading damage to the compressor and motor windings.

• Specs: 3-Pole | 25 Amps FLA | 115V AC Coil | 240/480/600V load side rated | Factory-matched OEM tolerances
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM contactors use factory-spec silver-alloy contact tips and coil windings that meet original design life targets. Generic contactors often use lower-grade contact materials that pit and fail prematurely under high-cycle commercial loads.
• Install Difficulty: 3/5 — Disconnect all power at the breaker and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or camera to document wiring positions prior to removal. Control wiring and load-side lugs must be re-terminated securely to spec torque.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
