OEM Carrier Single Run Capacitor P291-1003 for Model PY1PEA048120AFBA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PY1PEA048120AFBA packaged heat pump unit. A single run capacitor maintains a consistent phase-shifted electrical current to keep either the compressor or the fan motor running smoothly after startup. When this capacitor weakens or fails, you'll typically notice symptoms such as a humming compressor that won't start, frequent short-cycling, elevated amp draws, or a complete failure to cool or heat — all classic signs of capacitor degradation.

  • Specs: Single run capacitor | Factory-matched MFD rating and voltage | Oval or round case (verify against unit data plate) | Manufactured to OEM ±5% tolerance standards
  • OEM vs Generic: This is a genuine OEM Carrier part. Generic capacitors commonly carry ±10% MFD tolerance, which causes premature motor and compressor wear. OEM ensures the exact electrical characteristics Carrier engineered into the PY1PEA048120AFBA.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to confirm discharge. Photograph all wiring connections before removal. This is a common DIY-friendly repair for experienced homeowners or any certified HVAC technician.
  • Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our warehouse when placed before 3 PM local time.

Compatibility: Engineered for the Carrier PY1PEA048120AFBA packaged heat pump. Always cross-reference the MFD rating and voltage printed on your existing capacitor's label and the unit's data plate before ordering to confirm fitment. Our HVAC parts specialists are available to verify compatibility before you buy — just reach out before placing your order.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PEA048120AFBA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PEA048120AFBA. 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 PY1PEA048120AFBA?
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.
