OEM Carrier Single Run Capacitor P291-1503 for Model PH1ZPA048000ABAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PH1ZPA048000ABAA packaged heat pump system. A run capacitor provides the continuous phase-shifted electrical boost that keeps either the compressor or condenser fan motor spinning at full efficiency. When it fails, you'll typically notice a loud humming with no motor movement, intermittent shutdowns, or a complete no-start condition — all signs the capacitor can no longer hold its charge.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V or 440V rated (verify on unit data plate) | Cylindrical case | OEM-spec ±5% tolerance for precise motor protection
  • OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory specifications. Generic alternatives often carry a wider ±10% MFD tolerance, which can accelerate motor winding stress and reduce compressor lifespan over time.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling — it can hold a lethal charge even when power is off. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all terminal wiring before disconnecting.
  • Warranty: Backed by a 1-year OEM manufacturer warranty. Ships same business day from our fully stocked warehouse.

Compatibility: Engineered specifically for the Carrier PH1ZPA048000ABAA 4-ton packaged heat pump unit. Always cross-reference the MFD and voltage ratings printed on your original capacitor and unit data plate before ordering to confirm an exact match. Need help verifying fitment? Our HVAC parts specialists confirm compatibility before you buy — no guesswork, no returns.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH1ZPA048000ABAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH1ZPA048000ABAA. 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 PH1ZPA048000ABAA?
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.
