OEM Payne AC Run Capacitor Replacement for Model PA4GNXB30000AA

This genuine OEM Payne run capacitor is built specifically for the PA4GNXB30000AA air conditioning condenser. The run capacitor delivers the steady electrical charge that keeps the compressor and condenser fan motor turning at full torque throughout each cooling cycle. A bulging, leaking, or out-of-spec capacitor is the number-one reason an outdoor unit hums but won't spin up, trips the breaker, or short-cycles during peak heat. Matched precisely to the microfarad rating and voltage of the PA4GNXB30000AA, this part installs as a true drop-in replacement. Swapping a run capacitor is an easy, beginner-level repair that most people finish in about 15 minutes using a screwdriver and nut driver — just cut power and safely discharge the old capacitor first. Protecting your compressor with a precision OEM capacitor avoids the early failures and weak starts that generic substitutes often cause. Don't let a few-dollar part take out an expensive compressor. In stock now and ships same-day when you order before 3PM CST.

Frequently Asked Questions

Does this Run Capacitor fit my Payne Model PA4GNXB30000AA?
Yes. This is the factory-specified OEM run capacitor for the Payne Model PA4GNXB30000AA. 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 PA4GNXB30000AA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
