OEM Payne AC Run Capacitor Replacement for Model PA4GNAB42000AA

This genuine OEM Payne run capacitor is the factory-correct replacement for the PA4GNAB42000AA air conditioning condenser. The run capacitor stores and releases the electrical charge that keeps the compressor and condenser fan motor running with proper torque every time your system calls for cooling. When the capacitor degrades, the most common symptoms are a humming outdoor unit that won't start, a fan blade that won't turn, nuisance breaker trips, and short-cycling during peak heat. Matched exactly to the microfarad rating and voltage of the PA4GNAB42000AA, this part is a direct drop-in with no modifications needed. Replacing a run capacitor is a simple, beginner-level repair most homeowners finish in around 15 minutes using a screwdriver and nut driver — always cut power and discharge the old capacitor first. Choosing a true OEM capacitor over a generic protects your compressor from hard starts and shortens downtime. In stock and ships same-day when you order before 3PM CST.

Frequently Asked Questions

Does this Run Capacitor fit my Payne Model PA4GNAB42000AA?
Yes. This is the factory-specified OEM run capacitor for the Payne Model PA4GNAB42000AA. 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 run capacitor on my Payne Model PA4GNAB42000AA?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this run capacitor 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 run capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
