OEM Carrier Single Run Capacitor 4 MFD 370V for Payne PY3PEA060090AA Packaged Gas/Electric Unit

This is the factory-authorized OEM replacement single run capacitor for the Payne PY3PEA060090AA single-packaged gas heating/electric cooling unit — a 5-ton, 460V/3-phase, 90,000 BTU commercial-grade packaged rooftop system. Part number P291-0403 serves the condenser fan motor circuit, storing and releasing the electrical charge needed to start and sustain the motor on every cooling cycle. A companion capacitor, P291-2503 (25 MFD 370V), serves the compressor circuit on the same unit. When the run capacitor weakens or fails, you'll typically notice the condenser fan struggling to start, humming without spinning, overheating, or tripping the unit's high-pressure lockout — all leading to a no-cooling condition.

  • Specs (P291-0403): 4 MFD (microfarad) | 370 VAC | Oval case | ±6% capacitance tolerance | 50/60 Hz | Replaces HC90AA004, HC91CA004, HC90AB004, 97F5704
  • OEM vs Generic: Factory Authorized Parts (FAP) capacitors are manufactured to Carrier/Payne's exact tolerance spec and tested to 60,000 service hours. Generic units often run ±10% MFD variance, accelerating motor wear and risking compressor damage in a packaged commercial unit.
  • Install Difficulty: 2/5 — Always discharge the capacitor before touching terminals. Tools required: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring before disconnecting. Verify voltage rating matches your unit's data plate.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse in original manufacturer packaging.

Compatibility: Designed for the Payne PY3PEA060090AA single-packaged gas heat/electric cooling unit (5-ton, 460V/3Ø/60Hz, 90,000 BTU heat). Also compatible with other Carrier/Bryant/Payne models specifying a 4 MFD 370V oval single run capacitor — always verify MFD and voltage ratings on your unit's data plate before ordering.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PEA060090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PEA060090AA. 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 Carrier PY3PEA060090AA?
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 Carrier 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 Carrier 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.
