OEM Payne Run Capacitor PA4ANG018000BAAA for Model PA4ANG018000

Keep your Payne PA4ANG018000BAAA air conditioner running efficiently with this genuine OEM run capacitor. The run capacitor provides the continuous electrical phase shift needed to keep the compressor and condenser fan motor turning smoothly, improving energy efficiency and protecting the system from overheating. A weak or failed capacitor is one of the most common causes of a unit that hums but won't start, or that trips the breaker on a hot day. This exact-fit replacement is matched to the PA4ANG018000BAAA model for correct microfarad and voltage rating, so you get reliable starts and full cooling capacity. Installation is a moderate DIY job for the comfortable homeowner — disconnect power, discharge the old capacitor, note the wiring, and swap it in within 20 minutes. We recommend a licensed HVAC technician if you're unsure about capacitor discharge safety. Every order placed before 3PM CST ships the same day so you can get cooling back fast. Buy with confidence: genuine OEM Payne parts, in stock and ready to ship.

Frequently Asked Questions

Does this Run Capacitor fit my Payne Model PA4ANG018000?
Yes. This is the factory-specified OEM run capacitor for the Payne Model PA4ANG018000. 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 run capacitor on my Payne Model PA4ANG018000?
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 run 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 run 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.
