OEM Payne Start Capacitor P281-8806 for Model PA4RNG018000BBAA

This is the factory OEM start capacitor (part number P281-8806) for the Payne PA4RNG018000BBAA split-system condenser. A start capacitor provides the short but powerful burst of electrical energy needed to get the compressor motor spinning from a dead stop. Unlike run capacitors, which stay energized continuously, the start capacitor drops out of the circuit once the motor reaches operating speed. When it fails, you'll typically experience hard-start attempts, a loud hum with no compressor engagement, tripped breakers, or a complete no-start condition — all symptoms that leave you without cooling on the hottest days.

  • Specs: OEM-matched microfarad (MFD) and voltage rating | Factory-specified ±5% tolerance | Designed for Payne PA4RNG018000BBAA 1.5-ton split-system condenser application
  • OEM vs Generic: This OEM unit is manufactured to Payne's exact electrical specifications. Aftermarket start capacitors commonly exceed ±10% MFD tolerance, placing undue stress on the compressor motor windings and shortening equipment lifespan — a false economy on a costly sealed compressor.
  • Install Difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to confirm discharge. Always photograph all wiring connections before removal. If you are unfamiliar with high-voltage components, consult a licensed HVAC technician.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered specifically for the Payne PA4RNG018000BBAA condenser unit. Always cross-reference the MFD and voltage ratings printed on your existing capacitor's label or the unit data plate before finalizing your order. Our parts specialists are available to confirm fitment — reach out before you order if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Capacitor fit my Payne PA4RNG018000BBAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA4RNG018000BBAA. 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 PA4RNG018000BBAA?
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.
