OEM Payne Run Capacitor PA2PNB042000AA-RC for Model PA2PNB042000AA

This OEM Payne run capacitor is the genuine factory replacement for the PA2PNB042000AA 3.5-ton air conditioner condensing unit. The dual run capacitor provides the steady electrical phase shift that keeps both the compressor and outdoor fan motor running smoothly, preventing hard starts, high amp draw, and premature compressor failure. A bulging, leaking, or weak capacitor is the most common reason an outdoor unit hums but won't start or trips the breaker. Manufactured to the exact microfarad and voltage ratings of your PA2PNB042000AA, this capacitor is a guaranteed electrical match for reliable cooling and proper motor performance. Installation is an easy 15-30 minute repair for an experienced DIYer or technician using basic hand tools—just safely discharge the old capacitor and disconnect power first. Always confirm MFD ratings against your existing part before installing. Backed by genuine Payne quality for long, dependable service life. In stock and ships same-day on orders placed before 3PM CST. Order now from NationalHVACParts.com.

Frequently Asked Questions

Does this Run Capacitor fit my Payne Model PA2PNB042000AA?
Yes. This is the factory-specified OEM run capacitor for the Payne Model PA2PNB042000AA. 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 PA2PNB042000AA?
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?
