OEM Carrier 2-Pole Contactor 40 Amp 24V Coil — HN52KD020 for Model PY1RJA060074AAWA

This OEM contactor (part number HN52KD020) is the factory-specified high-voltage switching relay for the Carrier PY1RJA060074AAWA packaged unit. The contactor acts as the primary electrical switch that closes when the thermostat calls for cooling, routing 240V power to the compressor and condenser fan motor. A failing contactor is one of the most common causes of an air conditioner that simply won't turn on — or one that hums loudly, trips the breaker repeatedly, or starts and stops erratically. Burned or pitted contacts are a telltale sign it's time to replace.

  • Specs: 2-Pole | 40 Amp (50 Amp Resistive) | 24V coil voltage | Direct OEM replacement for HN52KD020 — also replaces HN52KD025, HN52KD025A, 3100-30Q1028TT
  • OEM vs Generic: This is a genuine Carrier factory-authorized part engineered to exact contact gap, coil pull-in voltage, and amp rating specifications. Aftermarket contactors often use thinner contact material that pits faster under high inrush current, shortening service life significantly.
  • Install Difficulty: 2/5 — Disconnect all power at the breaker and outdoor disconnect before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting terminals. Discharge any capacitors in the unit before working nearby.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY1RJA060074AAWA packaged unit. Cross-references include HN52KD025, HN52KD025A, and 3100-30Q1028TT. Always verify pole count, amperage, and coil voltage against your unit's data plate before ordering. Have a fitment question?

Frequently Asked Questions

Does this Contactor fit my Carrier PY1RJA060074AAWA?
Yes. This is the factory-specified OEM contactor for the Carrier PY1RJA060074AAWA. 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 PY1RJA060074AAWA?
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.
How fast does National HVAC Parts ship?
