OEM Carrier Single Run Capacitor P291-1503 for Model PG8JAA036045ACJA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PG8JAA036045ACJA packaged gas/electric unit. The single run capacitor provides the continuous phase-shifted voltage needed to keep the blower or condenser fan motor running efficiently after startup. When this capacitor weakens or fails, you'll typically notice symptoms such as a humming motor that won't spin, intermittent shutdowns, sluggish motor starts, or the unit tripping on thermal overload due to motor strain.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case | OEM tolerance ±3% for precise motor protection
  • OEM vs Generic: This is the genuine OEM Carrier part, built to exact factory specifications. Generic aftermarket capacitors frequently carry a wider ±10% MFD tolerance, which accelerates motor winding wear and can shorten the service life of your blower or fan motor significantly.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, and a multimeter capable of MFD testing. Photograph all wiring connections before disconnecting to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3PM local time.

Compatibility: Designed for the Carrier PG8JAA036045ACJA packaged gas/electric unit. Always verify the MFD and voltage ratings printed on your existing capacitor's label or your unit's data plate before ordering to confirm fitment. Not sure? Our HVAC parts specialists are available to verify compatibility before you place your order — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor P291-1503 — PG8JAA036045ACJA?

How do I replace the capacitor on my Carrier OEM Carrier Single Run Capacitor P291-1503 — PG8JAA036045ACJA?
Difficulty: Easy (20–30 min)

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?
