OEM Carrier Contactor 2-Pole 24V Coil for Model PH13NR04800GAAAA

This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Carrier PH13NR04800GAAAA heat pump / condensing unit. The contactor is a high-voltage relay that acts as the main power switch for your system — when the thermostat calls for cooling or heating, the 24V control circuit energizes the contactor coil, closing the high-voltage contacts and sending line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioning system that won't turn on, hums without starting, or runs continuously without shutting off.

  • Specs: 2-Pole design | 24V AC coil voltage | Factory-rated amperage matched to OEM specification | Direct drop-in replacement for Carrier OEM part HN51KC024
  • OEM vs Generic: This OEM contactor uses factory-grade contact materials and coil windings that meet exact Carrier tolerances. Generic contactors may use lower-grade contact alloys, leading to premature pitting, arcing, and compressor damage over time.
  • Install Difficulty: 2/5 — Always disconnect and lock out power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Replacement typically takes 20–30 minutes.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier PH13NR04800GAAAA 4-ton heat pump condensing unit. Always verify coil voltage and pole configuration on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists are available to confirm fitment before you buy — same-day shipping on all in-stock orders.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR04800GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR04800GAAAA. 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 PH13NR04800GAAAA?
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?
