OEM Carrier 3-Pole Contactor 25A 115V — HN53CB115 for Model 09DK034500

This is the genuine OEM replacement contactor for the Carrier 09DK034500 commercial HVAC unit. The contactor is the high-voltage switching relay that energizes the compressor and fan circuits every time your system calls for cooling or heating. A failing contactor is one of the most common causes of a complete system no-start: you may hear a click or buzz from the control board with zero mechanical response, or experience intermittent lockouts and nuisance tripping under load. Replacing it with the factory-specified OEM part restores reliable, full-rated switching performance.

  • Specs: 3-Pole | 25A Full Load Amps | 115V (120VAC) Coil | 35A Resistive Rating | Definite Purpose Design | OEM Part # HN53CB115
  • OEM vs Generic: This is a genuine Carrier factory part manufactured to exact contact gap, coil pull-in voltage, and heat-dissipation specifications. Aftermarket contactors frequently use lower-grade silver-alloy contacts that pit and weld faster, shortening system life.
  • Install difficulty: 3/5 — Requires disconnecting line-voltage wiring from a multi-pole block. Always lock out/tag out power at the disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil continuity before re-energizing. Photograph all wiring before removal.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse.

Compatibility: Factory-matched replacement for Carrier model 09DK034500 commercial HVAC equipment. Cross-references include HN53TB115, HN52KC016, and HN72AZ301. Verify pole count, amperage, and coil voltage against your unit's data plate prior to ordering. Our fitment specialists are available to confirm compatibility before you buy — order today and ship the same day.
