OEM Carrier 3-Pole Contactor 208/240V 40A for Model RSA1000M5J

This is the factory OEM replacement contactor for the Carrier RSA1000M5J packaged or split-system unit. The contactor is the critical high-voltage relay that receives a low-voltage signal from the control board and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to worn contacts, pitting, or a burned coil — the unit will fail to energize at all, hum without starting, or trip the breaker repeatedly. Replacing the contactor with the correct OEM part restores factory-specified performance and protects your compressor investment.

• Specs: 3-Pole | 208/240V coil | 40A FLA (Full Load Amps) | 50A RES (Resistive) | 24VAC-compatible control circuit | OEM Part # HN53CD209
• OEM vs Generic: OEM contactors use factory-grade silver-alloy contact tips rated for exact load cycles. Generic aftermarket contactors often use lower-grade contacts that pit faster under the high inrush current of scroll compressors, leading to premature failure.
• Install Difficulty: 3/5 — Line voltage is present in the condenser panel. Always shut off power at the disconnect AND breaker before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, non-contact voltage tester. Photograph all wiring before disconnecting terminals. A licensed HVAC technician is recommended for this repair.
• Warranty: 1-year OEM manufacturer warranty. In-stock — ships same business day from our warehouse.
