OEM Carrier 2-Pole Contactor 40 Amp 24V for Model PH12NA06000GAGAA

This OEM Carrier contactor (part number HN52KD020) is the factory-specified high-voltage relay for the Carrier PH12NA06000GAGAA heat pump system. The contactor acts as the main power switch for your outdoor unit — when the thermostat calls for cooling or heating, the 24V control board energizes the contactor coil, closing the high-voltage circuit to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an outdoor unit will not respond at all, hum with no startup, or intermittently lose power mid-cycle. Pitted or burned contacts from arcing are the telltale sign it's time to replace.

  • Specs: 2-Pole | 40 Amp (50A resistive rated) | 24V AC coil | 50/60 Hz | Factory-matched contact gap and spring tension
  • OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. Generic contactors often use lower-grade contact alloys that pit and burn faster, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and the disconnect box before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH12NA06000GAGAA. Also replaces legacy part numbers HN52KD025, HN52KD025A, and 3100-30Q1028TT. Verify pole count, amperage, and coil voltage against your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier PH12NA06000GAGAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH12NA06000GAGAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier PH12NA06000GAGAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
