This OEM Carrier 3-pole contactor is the factory-specified replacement for the Carrier ROA0750L2Y commercial rooftop/packaged unit. The contactor functions as a high-current relay, receiving a low-voltage signal from the control board and closing the circuit to deliver line voltage to the compressor and fan motors. When a contactor fails, you'll typically see the unit fail to energize at all, hear persistent chattering or buzzing from the contactor coil, notice pitted or burned contact tips, or find the system locked in an always-on condition that won't shut off.
Compatibility: Engineered as a direct OEM replacement for Carrier ROA0750L2Y commercial packaged equipment. This contactor supersedes OEM part number HN53CD209 under updated part number HN53HF212 — both are fulfilled identically. Verify your unit's data plate for 208/240V coil voltage and 3-pole configuration before ordering. Our fitment team is available to confirm compatibility before you buy.
