OEM Carrier 3-Pole Contactor 115V 40A — HN53CD115 for Model 07EA022411

This OEM Carrier contactor (part number HN53CD115) is the factory-specified high-voltage switching relay for the Carrier 07EA022411 packaged or commercial HVAC unit. The contactor acts as the primary electrical switch that energizes the compressor and fan motor circuits whenever the thermostat calls for cooling. When a contactor fails, the most common symptoms are a system that won't start despite the thermostat signaling demand, audible buzzing or chattering at the contactor terminals, or burned/pitted contact points that cause intermittent or complete loss of cooling.

• Specs: 115V coil voltage | 40 Amp rating | 3-Pole configuration | OEM-matched contact gap and spring tension for full electrical isolation
• OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory specifications. Generic aftermarket contactors often use lower-grade silver-alloy contacts that pit and arc faster under load, shortening service life and risking compressor damage from voltage drop.
• Install difficulty: 3/5 — Always disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter for coil continuity check, and camera/phone to photograph wiring before removal. Label all wires prior to disconnecting terminals.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered as a direct OEM replacement for Carrier model 07EA022411. Verify your unit's coil voltage and pole configuration on the data plate or existing contactor label before ordering. Our HVAC parts specialists are available to confirm fitment before you purchase — no guesswork, no returns.
