OEM Carrier 2-Pole Contactor 40 Amp 24V — HN52KD020 for Model PH12NA06000GABAA

This OEM 2-pole contactor is the factory-specified replacement part for the Carrier PH12NA06000GABAA heat pump system. The contactor is the high-voltage switching relay that controls power delivery to the compressor and condenser fan motor. When the 24V thermostat signal energizes its coil, the contactor closes and allows line-voltage power to flow. A failed contactor is one of the most common reasons an air conditioner or heat pump compressor won't start — symptoms include a humming sound with no compressor operation, a unit that won't respond to the thermostat, or visibly burned/pitted contacts.

  • Specs: 2-Pole | 40 Amp | 50 Amp Resistive | 24V AC Coil | Replaces HN52KD025, HN52KD025A, 3100-30Q1028TT
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact factory tolerances. Generic aftermarket contactors often use lower-grade contact materials that pit and arc faster, leading to premature compressor failure.
  • Install Difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Direct OEM replacement for Carrier model PH12NA06000GABAA. Always verify your existing contactor's pole count, amperage rating, and coil voltage against your unit's data plate before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions.
