OEM Carrier 2-Pole Contactor 24V 40A — HN52PD024 for Model PH3ANA060000BAAA

This OEM Carrier contactor (part #HN52PD024) is the factory-specified high-voltage relay for the Carrier PH3ANA060000BAAA packaged unit. The contactor is the critical electromechanical switch that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When contactors fail — through pitted contacts, a burned coil, or a mechanically stuck plunger — the most common symptom is an air conditioner that simply won't turn on, even when the thermostat is calling for cooling. Secondary symptoms include visible arcing, chattering, or a unit that runs continuously and won't shut off.

• Install difficulty: 3/5 — Line voltage is present inside the unit. Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wire connections before removal.
