The contactor is a high-voltage relay that switches power to the compressor and condenser fan motor each time your thermostat calls for cooling. When it fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the outdoor unit simply will not energize, leaving you with warm air and a running air handler with no cooling effect. In some cases a failed contactor will weld shut, causing the outdoor unit to run continuously regardless of thermostat demand.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | Heavy-duty silver-alloy contacts | Rated for residential split-system compressor loads | Direct OEM replacement for part number HN51KB024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM contactor is wound and rated to exact Payne specifications.
