This OEM contactor (part number HN52TC040) is the factory-specified replacement for the Carrier GC048HSRCDET1XX1 packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to supply line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will either fail to start entirely, run continuously without shutting off, or trip the breaker repeatedly.
Compatibility: Engineered specifically for the Carrier GC048HSRCDET1XX1 packaged unit. Confirm your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our team is available to verify fitment — contact us before you buy if you have any questions.
