OEM Payne Start Capacitor P281-8806 for Model PA4RNG018000BAAA

This is the factory-specified OEM start capacitor (part number P281-8806) for the Payne PA4RNG018000BAAA split-system air conditioner. The start capacitor delivers the high-voltage jolt needed to get the compressor motor spinning from a dead stop. Without a functioning start capacitor, the compressor will hum loudly, trip on overload, or fail to start entirely — leaving your system unable to cool. Replacing a failed start capacitor promptly protects the compressor from burnout caused by locked-rotor current draw.

  • Specs: OEM-matched capacitance (MFD) and voltage rating | Designed for Payne PA4RNG018000BAAA 1.5-ton split-system condenser | Factory tolerance ±3% for precise motor protection | Replaces OEM part number P281-8806
  • OEM vs Generic: This OEM unit is manufactured to exact Payne/Carrier factory specifications. Generic start capacitors frequently run outside ±10% tolerance, increasing compressor wear, hard-start events, and the risk of premature compressor failure — the most expensive repair in any system.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Payne PA4RNG018000BAAA 1.5-ton residential split-system condenser. Always verify the capacitance (MFD) and voltage rating on your existing capacitor's data label before ordering to confirm an exact match. If you have questions about fitment, our HVAC parts specialists will verify compatibility before your order ships — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Payne PA4RNG018000BAAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA4RNG018000BAAA. 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 PA4RNG018000BAAA?
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.
