OEM Payne Start Capacitor P281-1766 for Model PA4ANG018000BBAA

This is the factory OEM start capacitor (part number P281-1766) for the Payne PA4ANG018000BBAA split-system air conditioner. The start capacitor delivers the high-torque electrical boost the compressor motor needs to overcome inertia and reach operating speed. When this component fails, you'll notice symptoms such as a humming condenser unit that never fully starts, repeated tripped breakers, or a compressor that struggles to kick on and quickly shuts back down on thermal overload.

  • Specs: OEM-matched microfarad (MFD) rating | Factory-specified voltage rating | Designed for single-phase compressor start duty | ±5% tolerance per factory specification for reliable compressor engagement
  • OEM vs Generic: This is a genuine OEM replacement carrying the exact electrical specifications Payne engineered for the PA4ANG018000BBAA. Aftermarket start capacitors frequently ship with wider MFD tolerances that place undue stress on compressor windings, shortening equipment life and potentially voiding manufacturer warranties.
  • Install Difficulty: 3/5 — A start capacitor carries a dangerous residual charge even after power is disconnected. Always discharge the capacitor using an insulated resistor or discharge tool before handling any terminals. Tools required: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify the old capacitor has fully discharged. Photograph all wiring connections before removal.
  • Warranty: Backed by a 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered specifically for the Payne PA4ANG018000BBAA 1.5-ton split-system air conditioner. Always verify the MFD and voltage ratings printed on your existing capacitor's label or your unit's data plate before completing your order. Our parts specialists are available to confirm fitment — reach out before you buy for total peace of mind. In stock and ready to ship today.

Frequently Asked Questions

Does this Capacitor fit my Payne PA4ANG018000BBAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA4ANG018000BBAA. 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 PA4ANG018000BBAA?
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.
