OEM Payne Contactor HN51KC024 for Model PA4ANG042000BBAA

This genuine Payne contactor (HN51KC024) is the electrical switch that powers your Payne PA4ANG042000BBAA condensing unit on and off in response to the thermostat. When the 24-volt control coil energizes, the contactor closes its line-voltage contacts to feed the compressor and fan motor; worn or pitted contacts cause chattering, no-cool calls, and welded-closed units that never shut off. This OEM contactor is matched to the PA4ANG042000BBAA's amperage and coil voltage for a direct, reliable replacement with no modification. Installation is straightforward for confident DIYers and pros alike, taking roughly 20-30 minutes: disconnect power, photograph the wiring, transfer leads one at a time, and secure the new contactor in place. Genuine Payne parts guarantee correct contact rating and long service life under repeated switching cycles. Replacing a burnt contactor restores dependable cooling and protects your compressor from damaging voltage drops. Backed by our parts guarantee and expert support. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Payne Model PA4ANG042000BBAA?
Yes. This is the factory-specified OEM contactor for the Payne Model PA4ANG042000BBAA. 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 Model PA4ANG042000BBAA?
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.
