OEM Payne Start Capacitor P281-1766 for Model PA3ANA048000BBAA

This is the genuine OEM start capacitor (part number P281-1766) factory-specified for the Payne PA3ANA048000BBAA 4-ton split-system air conditioner. The start capacitor delivers the high-voltage electrical boost the compressor motor needs to overcome inertia and reach operating speed. When this component fails, you'll notice symptoms such as the compressor humming but not starting, repeated tripped breakers, hard-start attempts, or the outdoor unit failing to energize entirely — even when the thermostat is calling for cooling.

  • Specs: OEM start capacitor | Factory-matched MFD and voltage rating | Engineered to exact Payne tolerances | Round case design for direct drop-in fitment on PA3ANA048000BBAA units
  • OEM vs Generic: This genuine Payne OEM capacitor is manufactured to strict ±5% MFD tolerances, ensuring reliable compressor starts and protecting motor windings from stress. Off-brand replacements frequently drift outside tolerance, causing premature compressor wear and shortened equipment life.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals — stored charge can cause serious injury. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed and verified for the Payne PA3ANA048000BBAA 4-ton (048) split-system air conditioning condenser. Always cross-reference the MFD rating and voltage stamped on your existing capacitor or the unit's data plate before ordering to confirm fitment. Have a question about compatibility? Our HVAC parts specialists verify fitment before you buy — reach out before placing your order and we'll confirm the correct part for your unit.

Frequently Asked Questions

Does this Capacitor fit my Payne PA3ANA048000BBAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA3ANA048000BBAA. 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 PA3ANA048000BBAA?
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.
