OEM Carrier 2-Pole Contactor HN53CD024 for Model PF1AJB072000AAGC

This OEM contactor (part number HN53CD024) is the factory-specified replacement for the Carrier PF1AJB072000AAGC packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or contacts that weld shut — your system will either refuse to start entirely, run continuously without cycling off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage matched to PF1AJB072000AAGC | OEM part number HN53CD024 | Screw-terminal connections for secure field wiring
  • OEM vs Generic: This OEM contactor meets Carrier's exact coil voltage and contact ampacity specifications. Generic contactors frequently use lower-grade contact materials that pit and arc faster under high-cycle loads, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed and tested for the Carrier PF1AJB072000AAGC packaged unit. Always confirm coil voltage and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to verify fitment — just reach out before you buy. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier PF1AJB072000AAGC?
Yes. This is the factory-specified OEM contactor for the Carrier PF1AJB072000AAGC. 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 PF1AJB072000AAGC?
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?
