OEM Carrier 3-Pole Contactor 25A 115V for Model 09DK074100

This is the genuine OEM replacement contactor for Carrier model 09DK074100 commercial HVAC equipment. The contactor is a high-voltage relay that controls power delivery to the compressor and fan motors. When it fails, the unit will typically not start, hum without engaging, exhibit burned or pitted contacts, or trip repeatedly — leaving you with no cooling or heating. Replacing a worn contactor promptly protects downstream components like the compressor from damaging voltage irregularities.

• Specs: 3-Pole | 25 Amp FLA | 35A RES rating | 115V / 120VAC coil voltage | Hartland Controls HCCY3XT01DT103 equivalent | Factory OEM part number HN53CB115
• OEM vs Generic: This is a genuine Carrier factory part — not an aftermarket substitute. OEM contactors are manufactured to exact coil pull-in voltage and contact gap specifications, ensuring reliable switching life and protection of your compressor investment. Generic contactors often use lower-grade contact alloys that pit and weld faster under load.
• Install difficulty: 3/5 — Always shut off power at the disconnect and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or a phone camera to photograph existing wiring before removal. Line-voltage terminals require torque to spec — do not over-tighten.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse. Free shipping on qualifying orders.
