OEM Carrier 2-Pole Contactor 40 Amp 24V Coil — HN52TC040 for Model TCHC0250HEFMRAF501

This is the genuine OEM Carrier contactor (part number HN52TC040), factory-specified for the Carrier TCHC0250HEFMRAF501 system. The contactor is the high-voltage relay that closes the circuit between your disconnect and compressor/condenser fan motor every time a cooling call is made from the thermostat. When it fails — due to pitted contacts, a burned coil, or a seized plunger — the outdoor unit will not energize, leaving the system blowing warm air or failing to start entirely. You may also hear a continuous hum from the condenser cabinet as the coil energizes but the contacts refuse to pull in.

• Specs: 2-Pole | 40 FLA (Full Load Amps) | 24V 50/60Hz coil voltage | Definite purpose contactor | Direct OEM drop-in replacement
• OEM vs Generic: Genuine Carrier OEM contactors are wound and rated to exact factory specifications, ensuring proper pull-in voltage, correct contact gap, and long service life. Generic contactors may use thinner contact material and looser coil tolerances, risking premature failure and compressor damage.
• Install Difficulty: 2/5 — Always shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter. Photograph all wiring connections before removal. The contactor mounts with two screws and all wires are terminal-screw connections — typically a 15–30 minute job for a qualified technician.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
