OEM Payne Contactor PA4GNAA42000AA for Model PA4GNAA42000AA

This OEM Payne contactor is a direct replacement for the electrical switching relay in Payne model PA4GNAA42000AA condensing units. The contactor controls power to your compressor and condenser fan motor, closing whenever the thermostat calls for cooling and opening when the cycle ends. Constant electrical arcing eventually pits or welds the contacts, producing symptoms like a unit that won't start, fails to shut off, or buzzes at the disconnect box. Installing this genuine factory-spec contactor restores clean, dependable switching and shields your compressor from harmful voltage irregularities. The job is moderate in difficulty—a qualified technician usually finishes in 20 to 30 minutes once power is off and the wiring is labeled. For safety, we recommend a licensed HVAC professional perform all electrical repairs. Built to your unit's exact specifications, this contactor ensures reliable operation for years to come. In stock and ready to ship right away. Orders placed before 3PM CST ship same-day, so your air conditioning system is back to cooling your home with minimal downtime.

Frequently Asked Questions

Does this Contactor fit my Payne Model PA4GNAA42000AA?
Yes. This is the factory-specified OEM contactor for the Payne Model PA4GNAA42000AA. 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 PA4GNAA42000AA?
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.
