OEM Carrier 2-Pole Contactor 40 Amp 24V Coil — HN52KD020 for Model PH10JA06000GABAA

This is the genuine OEM replacement contactor for the Carrier PH10JA06000GABAA packaged HVAC unit. The contactor is a high-voltage relay that controls power delivery to the compressor and condenser fan motor. When the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the high-voltage contacts and allowing the compressor to start. A failed contactor is one of the most common causes of an air conditioner that hums but won't start, trips a breaker, or simply won't turn on at all — even when the thermostat is calling for cooling.

  • Specs: 2-Pole | 40 Amp (50 Amp Resistive) | 24V Coil | OEM Part Number HN52KD020 | Replaces HN52KD025, HN52KD025A, 3100-30Q1028TT
  • OEM vs Generic: This is a factory-authorized Carrier part, matched exactly to the contact gap, coil pull-in voltage, and amp rating specified for the PH10JA06000GABAA. Generic contactors may use lower-grade contact materials that pit and burn faster, causing repeat failures within a single cooling season.
  • Install Difficulty: 2/5 — Always disconnect power at the breaker and wait 5 minutes before servicing. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire terminations before removal. Wires transfer one-to-one from old to new contactor.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before 3PM ship same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier PH10JA06000GABAA packaged units. Verify pole count, amperage, and coil voltage on your unit's data plate before ordering. Not sure if this is the right part? Our HVAC parts specialists verify fitment before every order — call or chat now and we'll confirm.
