OEM Payne Single Run Capacitor P291-1503 for Model PA2PNB042000AB

This is the factory-specified OEM single run capacitor (part number P291-1503) for the Payne PA2PNB042000AB split-system air conditioner. A single run capacitor provides the continuous electrical charge needed to keep either the compressor or the condenser fan motor running at peak efficiency. When this capacitor fails, you'll notice symptoms such as a humming unit that won't start, a fan or compressor that stops shortly after startup, or a system that trips the breaker due to excessive amp draw. Replacing this component promptly prevents costly secondary damage to the motor or compressor.

  • Specs: OEM-matched MFD rating and 370V/440V rated | Round or oval case as factory-specified | Tight ±3% tolerance for reliable motor performance | Verify exact MFD value on your unit's data plate before ordering
  • OEM vs Generic: This genuine OEM capacitor is manufactured to Payne's exact factory tolerances. Aftermarket capacitors commonly deviate ±10% MFD, which increases motor operating temperatures, accelerates wear, and can void equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor before handling terminals. Required tools: 1/4" nut driver, needle-nose pliers, and a multimeter to confirm full discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In stock and ships the same business day from our dedicated HVAC parts warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA2PNB042000AB split-system condenser (4-ton, R-410A). Always cross-reference the MFD rating and voltage printed on your existing capacitor or unit data plate to confirm fitment before installation. Our parts specialists are available to verify compatibility before you order — same-day shipping ensures you get your system back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Payne PA2PNB042000AB?
Yes. This is the factory-specified OEM capacitor for the Payne PA2PNB042000AB. 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 capacitor on my Payne PA2PNB042000AB?
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 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 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.
