OEM Carrier Single Run Capacitor P291-1503 for Model PH3PEA048000AA

This is the factory-specified OEM single run capacitor for the Carrier PH3PEA048000AA 4-ton packaged heat pump unit. Unlike a dual run capacitor, a single run capacitor is dedicated to one motor — either the compressor or the condenser fan — providing the precise phase-shifted electrical charge needed to start and sustain motor operation. When this capacitor weakens or fails, the affected motor may hum and refuse to start, trip its thermal overload, or cause the entire unit to short-cycle and shut down on a protection fault. Replacing it promptly prevents costly motor burnout.

  • OEM Part Number: P291-1503 | Factory-matched MFD and voltage rating for the Carrier PH3PEA048000AA | Round or oval case (verify orientation on your unit's data plate)
  • OEM vs Generic: This is a genuine Carrier OEM capacitor held to exact ±3% MFD tolerance. Aftermarket alternatives commonly run ±10%, which accelerates motor winding stress and can void your compressor warranty.
  • Install Difficulty: 2/5 — Always disconnect power at the breaker and discharge the capacitor fully before handling. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, insulated discharge resistor or screwdriver, multimeter. Photograph all terminal wiring before disconnecting leads.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed as a direct OEM replacement for the Carrier PH3PEA048000AA packaged heat pump (4-ton, R-410A). Always confirm the MFD rating and voltage printed on your existing capacitor's label before ordering — these specifications must match exactly for safe operation.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH3PEA048000AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH3PEA048000AA. 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 PH3PEA048000AA?
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.
