OEM Carrier 3-Pole Contactor 115V 40A (HN53CD115) for Model 07EA022511

This OEM 3-pole contactor is the factory-specified replacement part for the Carrier 07EA022511 commercial HVAC system. The contactor functions as the primary high-voltage switching relay, receiving a low-voltage signal from the control board and closing its poles to deliver line voltage to the compressor and other high-draw loads. When a contactor fails — due to pitted or burned contacts, coil burnout, or contact welding — the unit will either fail to start entirely, run continuously without cycling off, or trip breakers repeatedly. Replacing with the correct OEM part ensures factory-matched performance and long-term reliability.

• Specs: 115V coil voltage | 40 Amp rating | 3-Pole configuration | OEM part number HN53CD115 | Direct factory replacement
• OEM vs Generic: OEM contactors feature factory-spec contact materials and coil windings matched to the 07EA022511's control voltage. Generic alternatives may use lower-grade silver alloy contacts prone to accelerated pitting, especially under compressor inrush loads.
• Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, multimeter, needle-nose pliers. Photograph all wiring connections before removing the old contactor.
• Warranty: 1-year OEM factory warranty included. In-stock and ships same business day from our warehouse.
