This is the genuine OEM replacement contactor for the Carrier 09DE084100, factory part number HN52KC052. The contactor is the high-voltage switching relay that energizes the compressor and condenser fan motor every time your thermostat calls for cooling. When the contactor fails — due to burned contacts, a stuck plunger, or a failed 120V coil — the system simply won't start, or it may hum loudly without the compressor or fan ever engaging. Replacing it with the factory-specified OEM part restores precise, reliable switching and protects the compressor from the voltage irregularities that generic contactors can introduce.
Compatibility: Verified fit for Carrier model 09DE084100. Confirm coil voltage (120V) and amperage rating on your unit's data plate before ordering — some configurations may use a 24V coil variant. Not sure? Our HVAC parts specialists verify fitment before your order ships. Order today and get back up and running fast.
