OEM Payne Run Capacitor PA1ZNA042000AAAA for Model PA1ZNA042000AAAA

This OEM Payne run capacitor is the genuine factory replacement component for the PA1ZNA042000AAAA 3.5-ton air conditioning condenser. The run capacitor delivers a steady phase shift of electrical current to keep both the compressor and condenser fan motor running smoothly and efficiently, preventing hard starts, overheating, and premature motor failure. A weak or bulging capacitor is one of the most common causes of an outdoor unit that hums but won't start. This dual-rated capacitor is engineered to the exact microfarad and voltage specifications Payne built into the PA1ZNA042000AAAA, ensuring a precise electrical match and reliable cooling performance. Installation is straightforward for an experienced HVAC technician and typically takes under 30 minutes with the power disconnected; discharge the old capacitor before removal. Using a genuine OEM part protects your system warranty and avoids the fitment guesswork of generic substitutes. Orders placed before 3PM CST ship same-day. Keep your Payne system cooling all season with the correct factory capacitor.

Frequently Asked Questions

Does this Run Capacitor fit my Payne Model PA1ZNA042000AAAA?
Yes. This is the factory-specified OEM run capacitor for the Payne Model PA1ZNA042000AAAA. 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 PA1ZNA042000AAAA?
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?
