OEM Carrier 3-Pole Contactor 40A 120V Coil for Model 07EA022521

This is the factory-specified OEM replacement contactor for the Carrier 07EA022521 commercial and applied HVAC equipment. The contactor is the high-voltage switching relay that energizes the compressor and associated loads when the control circuit signals a call for cooling. When it fails — whether due to pitted contacts, a burned coil, or a welded/stuck contact — symptoms include the system failing to turn on at all, compressor lockout, or in some cases the compressor running continuously with no thermostat signal. Replacing a worn contactor promptly protects the compressor from costly damage.

• Specs: 3-Pole | 40 Amps | 120VAC (115V) Coil Voltage | 50/60 Hz | OEM Part Number HN53CD115 | Replaces legacy Carrier part numbers HN53CC115, HN53LB235, HN52LB242, HN52LB245, HN53LC202, and more
• OEM vs Generic: This is a genuine Carrier OEM contactor, manufactured to exact factory coil pull-in voltage and contact rating tolerances. Generic contactors may use lower-grade silver-alloy contacts that pit faster under compressor load cycling, dramatically shortening service life.
• Install difficulty: 3/5 — Requires complete system lockout/tagout (LOTO) before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter for coil continuity verification. Always photograph existing wiring before disconnecting terminals. Recommend megohm test on compressor windings while system is open.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model 07EA022521. This contactor supersedes multiple legacy Carrier part numbers — verify your unit's existing contactor pole count, amperage rating, and coil voltage on the data plate or wiring diagram before ordering.
