This is the genuine OEM Carrier contactor (part number HN53HF122), the factory-specified replacement for Carrier commercial refrigeration and HVAC equipment including the 06EW033610. The contactor is a high-voltage switching relay that energizes and de-energizes compressor and motor circuits on command from the 120V control circuit. When a contactor fails, the most common symptoms include the unit failing to start entirely, chattering or buzzing noises from the electrical panel, welded or pitted contacts causing the compressor to run continuously, or a complete loss of cooling or heating output.
Compatibility: Designed for Carrier model 06EW033610 commercial compressor/HVAC applications. Cross-references include OEM part numbers HN53HE122, HN53HF120, HN53LF212, HN53LE226, and Siemens 42EF35AFA. Verify pole count, amperage, and coil voltage against your unit's data plate and wiring diagram before ordering. Need fitment assistance? Our team confirms compatibility before you buy — ships same day.
