OEM Carrier 2-Pole Contactor 24V Coil for Model PY2PPB042060NB (HN52KC025)

This OEM replacement contactor is the factory-specified part for the Carrier PY2PPB042060NB packaged unit. The contactor is the high-voltage switching relay that closes the circuit to the compressor and condenser fan motor every time your thermostat calls for cooling. When a contactor fails — due to burned or pitted contact points, a stuck plunger, or a failed coil — the most common symptom is an air conditioner that simply won't turn on, even though the thermostat is calling and the circuit breaker is closed. In some cases, you may hear a buzzing or chattering sound as the coil struggles to pull in the contacts fully.
