OEM Carrier Single Run Capacitor P291-1503 for Model PG8JAA036045ADJA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PG8JAA036045ADJA packaged gas/electric unit. The run capacitor provides the continuous phase-shifted voltage needed to keep the blower or condenser fan motor running efficiently after startup. When this capacitor degrades or fails, symptoms include a humming motor that won't spin, intermittent shutdowns, overheating, or a complete no-start condition on the affected motor circuit.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case | ±5% tolerance per OEM specification — verify exact MFD on your unit's data plate
  • OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances. Aftermarket/generic capacitors frequently carry ±10% MFD variance, which accelerates motor winding wear, reduces efficiency, and can void equipment warranties.
  • Install Difficulty: 2/5 — Single run capacitors are among the most straightforward HVAC repairs. Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship the same business day from our warehouse.

Compatibility: Designed for the Carrier PG8JAA036045ADJA packaged gas/electric unit. Always cross-reference the MFD and voltage rating on your existing capacitor and equipment data plate before ordering to confirm fitment. Our HVAC parts specialists are available to verify compatibility before you buy — same-day shipping on all stocked orders.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8JAA036045ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8JAA036045ADJA. 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 PG8JAA036045ADJA?
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.
