OEM Carrier 2-Pole Contactor 30 Amp 24V — Replaces HN52KC025 for Model PH2PEB042000AB

This OEM Carrier 2-pole contactor is the factory-specified replacement for the Carrier PH2PEB042000AB condensing unit, superseding original part number HN52KC025 (current OEM successor: HN52KC024). The contactor is a high-current relay that uses a low-voltage 24V thermostat signal to switch 240V power to the compressor and condenser fan motor. When it fails, your system may refuse to start, short-cycle, run continuously without shutting off, or produce an audible chattering or humming at the outdoor unit — all clear signs the contactor's contacts are pitted, welded, or the coil has failed.

  • Specs: 2-Pole | 30 Amp FLA | 24V AC Coil | 50/60 Hz | Definite-purpose contactor | Factory-matched drop-in replacement for HN52KC025 / HN52KC024
  • OEM vs Generic: OEM contactors use factory-spec silver-alloy contact points rated to exact load tolerances. Generic contactors often use thinner contacts that pit and weld faster under high-cycle residential loads, shortening compressor life and risking a locked-out system mid-season.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter. Always photograph existing wiring before removing any leads. Discharge any residual capacitor charge nearby before working in the electrical compartment.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PH2PEB042000AB. Original part number HN52KC025 has been superseded by HN52KC024 — both are fulfilled by this listing. Verify pole count (2-pole), amperage (30A), and coil voltage (24V) against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you purchase.

Frequently Asked Questions

Does this Contactor fit my Carrier PH2PEB042000AB?
Yes. This is the factory-specified OEM contactor for the Carrier PH2PEB042000AB. 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 PH2PEB042000AB?
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?
