OEM Payne Single Run Capacitor P291-1503 for Model PA2PJB048000AB

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Payne PA2PJB048000AB 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 during normal operation. When it degrades or fails, common symptoms include a humming sound with no motor movement, intermittent shutdowns, or the unit tripping on thermal overload due to a struggling motor drawing excess current.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Round case design | ±5% tolerance to OEM specification — verify MFD value on your unit's data plate before ordering
  • OEM vs Generic: OEM part P291-1503 is manufactured to Payne's exact electrical tolerances. Generic aftermarket capacitors frequently ship with ±10% MFD variance, which accelerates motor winding wear and can shorten compressor service life by years.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify capacitance after install. Photograph all wiring connections before removal.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed specifically for the Payne PA2PJB048000AB 4-ton split-system air conditioner. Always cross-reference the MFD rating and voltage printed on your existing capacitor or equipment data plate to confirm correct fitment. Our parts specialists are available to verify compatibility before you order — get the right part the first time and avoid costly return shipping delays.

Frequently Asked Questions

Does this Capacitor fit my Payne PA2PJB048000AB?
Yes. This is the factory-specified OEM capacitor for the Payne PA2PJB048000AB. 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 PA2PJB048000AB?
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.
