This OEM contactor (part number HN53CD115) is the factory-specified replacement for the Carrier CP50P250P206020CP packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When a contactor fails — due to burned or pitted contacts — the most common symptom is the system failing to start entirely, or intermittent cooling with the outdoor unit unresponsive even when the thermostat is calling for cooling.
Compatibility: This contactor is designed specifically for the Carrier CP50P250P206020CP packaged unit. Before ordering, verify coil voltage and pole configuration on your unit's wiring diagram or data plate. If you have any questions about fitment, our HVAC parts specialists confirm compatibility before your order ships — no guesswork required.
