The contactor is a high-voltage relay that closes the circuit between the 24V control board signal and the high-voltage power supply to the compressor and condenser fan motor. When the contactor fails, the most common symptom is an air conditioner that simply will not turn on — the thermostat calls for cooling, but nothing happens. You may also notice pitted or burned contact points on the old unit, or hear a clicking or chattering sound as the coil attempts to pull in without making solid contact.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole configuration | 24V coil voltage | Rated for high-amperage compressor loads | OEM part numbers \u003cstrong\u003eHN53CB115\u003c\/strong\u003e and \u003cstrong\u003eHN53CD115\u003c\/strong\u003e — both are factory-authorized replacements for this model\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier contactors are manufactured to exact coil pull-in voltage tolerances and contact gap specifications.
