OEM Carrier 3-Pole Contactor 120V 35A — HN53CB115 for Model 09DK084600

The Carrier HN53CB115 is the factory-specified OEM 3-pole contactor for the Carrier 09DK084600 commercial HVAC unit. The contactor acts as the high-voltage switching relay that energizes the compressor and fan circuits when the 24V control board sends a call for cooling. When this contactor fails, the system will not respond to a thermostat demand — you may hear the control board click but the compressor and condenser fan remain completely off, or the unit may fail to de-energize, causing continuous operation and eventual burnout.
