OEM Carrier Contactor 2-Pole 24V Coil for Model 09DK054500

This is the factory-specified OEM replacement contactor for the Carrier 09DK054500 condensing unit, manufactured to Carrier's exact electrical specifications under part number HN53CB115. The contactor is the primary high-voltage switching relay in your system — it receives a 24V signal from the thermostat or control board and closes its contacts to send line voltage to the compressor and condenser fan motor. When a contactor fails, symptoms include the outdoor unit failing to energize on a call for cooling, a persistent audible hum with no compressor start, welded or pitted contacts causing the unit to run continuously, or complete loss of cooling with the air handler still operating normally.

• Specs: 2-Pole design | 24V AC coil voltage | Factory-matched amperage and contact rating for Carrier 09DK054500 | Constructed with silver-alloy contacts for superior conductivity and arc resistance
• OEM vs Generic: This is a genuine OEM Carrier part (HN53CB115), built to factory tolerances for coil pull-in voltage, contact gap, and thermal rating. Aftermarket contactors often use lower-grade contact alloys that pit or weld prematurely, leading to repeat failures and potential compressor damage.
• Install difficulty: 3/5 — Requires disconnecting power at the outdoor disconnect AND the main breaker before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, multimeter for voltage verification, needle-nose pliers. Always photograph or label all wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier 09DK054500 condensing unit. Always verify the OEM part number on the existing contactor's label and confirm coil voltage and pole configuration on your unit's data plate prior to ordering. Our technical team is available to confirm fitment before you buy — ensuring the right part arrives the first time.
