OEM Carrier 2-Pole Contactor HN52KC025 for Model PH1PPA060000AABA

This is the OEM factory-specified replacement contactor for the Carrier PH1PPA060000AABA packaged heat pump unit. The contactor is a high-voltage relay that switches line-voltage power to the compressor and condenser fan motor each time your thermostat calls for cooling or heating. A worn or failed contactor is one of the most common causes of a packaged unit that powers on at the thermostat but won't actually start — symptoms include buzzing or chattering at the contactor, pitted or burned contact points, or a unit that simply won't respond to thermostat demand.
