OEM Carrier 3-Pole Contactor 40A 24V for Model YAC60140YAC102AT — Part HN53CD025

This factory-authorized OEM contactor is the exact replacement specified for the Carrier YAC60140YAC102AT. The contactor is the high-voltage switching relay that completes the 240V power circuit to the compressor and condenser fan motor every time the thermostat calls for cooling. When it fails, the most common symptoms include the outdoor unit not energizing at all, the compressor dropping out mid-cycle, or visible pitting and welding of the contact points that cause the unit to run continuously even when the thermostat is satisfied.

• Specs: 3-Pole | 40 Amp | 24V AC Coil | 50/60 Hz rated | Lug-style terminals | Factory-matched OEM replacement for part number HN53CD025
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, not an aftermarket substitute. OEM contactors use silver-alloy contact tips rated for the exact load profile of this unit — generic contactors often use inferior alloys that pit and weld prematurely, leading to repeat failures.
• Install difficulty: 3/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and insulated wire terminals. Photograph all wiring connections before removing the old contactor. A 3-pole contactor has more wire terminals than a standard 2-pole — take care to label each line and load terminal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: This contactor is the OEM-specified replacement for Carrier model YAC60140YAC102AT. Verify your existing contactor's pole count (3-pole), amperage (40A), and coil voltage (24V) against your unit's data plate and existing part before ordering. Not sure?
