OEM Payne Contactor PA3GNAA42000AA for Model PA3GNAA42000AA

This OEM Payne contactor is the electrical switch that powers up the compressor and condenser fan motor in your PA3GNAA42000AA air conditioning unit. Each time your thermostat calls for cooling, the contactor's coil pulls the contacts closed to deliver line voltage to the major components. Over years of cycling, the contacts can become pitted, corroded, or stuck — leading to a unit that won't start, buzzes loudly, or runs nonstop. Installing this genuine replacement restores clean, reliable switching. Manufactured to factory specifications, it matches the original coil voltage and amperage rating for a true drop-in fit, so no modifications are required. The repair is well within reach for a confident DIYer: disconnect power at the service disconnect, take a photo of the existing wiring, transfer the leads one terminal at a time, and mount the new contactor in place — usually around 20 minutes. Rely on OEM-grade durability designed for your Payne system. In stock and shipping same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Payne Model PA3GNAA42000AA?
Yes. This is the factory-specified OEM contactor for the Payne Model PA3GNAA42000AA. 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 PA3GNAA42000AA?
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.
