OEM Payne 2-Pole Contactor 24V Coil for Model PA4RNG048000BAAA

This is the OEM factory-specified contactor (part number HN51KC024) for the Payne PA4RNG048000BAAA 4-ton split-system air conditioner. The contactor acts as the high-voltage relay that allows the low-voltage (24V) thermostat signal to switch on the high-voltage (240V) power to the compressor and condenser fan motor. When the contactor fails — due to worn contacts, pitting, or a stuck/burned coil — your air conditioner will either fail to start entirely, run continuously without shutting off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V coil voltage | 40A rated contacts | Direct OEM replacement, factory-matched to Payne PA4RNG048000BAAA specifications
  • OEM vs Generic: This OEM contactor uses factory-grade contact materials that resist arcing and pitting far longer than generic alternatives. Generic contactors often use lower-grade alloys that fail prematurely under high cycling loads common in 4-ton systems.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker panel 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. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Payne PA4RNG048000BAAA 4-ton split-system condenser. Always verify coil voltage and pole configuration on your unit's data plate before ordering. Not sure if this is the right part? Our HVAC parts specialists verify fitment before you buy — just reach out before placing your order.

Frequently Asked Questions

Does this Contactor fit my Payne PA4RNG048000BAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA4RNG048000BAAA. 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 Payne PA4RNG048000BAAA?
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 Payne 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 Payne 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?
