OEM Carrier 2-Pole Contactor 30 Amp 24V for Model PH1PEB042000AAAA

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier PH1PEB042000AAAA packaged unit. The contactor acts as the critical switch between your thermostat's 24V control signal and the high-voltage circuit powering the compressor and condenser fan. When your thermostat calls for cooling, the 24V coil energizes, closing the contacts and sending line voltage to the compressor. A failed contactor is one of the most common reasons an air conditioner won't turn on, hums without starting, or trips a breaker repeatedly.

  • Specs: 2-Pole (Double Pole) | 30 Amp RES rating | 24V AC coil voltage | 50/60 Hz | Replaces OEM part number HN52KC025 (superseded by HN52KC024)
  • OEM vs Generic: OEM contactors are manufactured to exact Carrier factory tolerances for contact gap, silver alloy content, and coil pull-in voltage. Generic alternatives often use lower-grade contact materials that pit and arc prematurely under residential load cycling, shortening compressor life.
  • Install difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Discharge any capacitors in the cabinet before touching adjacent components.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered to fit Carrier model PH1PEB042000AAAA packaged units. Note that HN52KC025 has been officially superseded by Carrier part HN52KC024 — this listing ships the current OEM-approved replacement. Always 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 PH1PEB042000AAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH1PEB042000AAAA. 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 PH1PEB042000AAAA?
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?
