This is the factory OEM replacement contactor (part number HN52TC040) for the Carrier GC048CBRNDET1XX1 packaged unit. The contactor is a high-voltage relay that acts as the primary switch between your thermostat's 24V control signal and the high-voltage power circuit running the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an air conditioner that won't turn on at all, a unit that runs continuously without cycling off, or visible pitting and burning on the contactor contacts from normal electrical arcing over time.
Compatibility: Designed specifically for the Carrier GC048CBRNDET1XX1 packaged gas/electric unit. Always verify coil voltage and pole configuration on your unit's data plate or wiring diagram before ordering. Our fitment specialists are available to confirm compatibility before you purchase — same-day shipping on all in-stock orders.
