OEM Carrier Single Run Capacitor 370V (P291-0403 / P291-1003 / P291-1503) for Model PY1PEB048115AAAA

These OEM single run capacitors are the factory-specified replacements for the Carrier PY1PEB048115AAAA packaged gas/electric unit. The PY1PEB048115AAAA uses three individual oval single run capacitors — one for the compressor motor, one for the condenser fan motor, and one for the indoor blower motor — rather than a combined dual run unit. When any one of these capacitors fails, you'll typically notice a humming sound with no motor movement, a motor that starts slowly and then trips, or an outright no-cooling/no-airflow condition. Replacing the failed capacitor with the correct OEM-rated unit restores proper torque, motor efficiency, and compressor longevity.

  • Part Numbers & Specs: P291-0403 — 4 MFD / 370V Oval Single | P291-1003 — 10 MFD / 370V Oval Single | P291-1503 — 15 MFD / 370V Oval Single | All oval case, 50/60 Hz, UL-recognized, RoHS compliant
  • OEM vs Generic: These are genuine Totaline/Carrier OEM capacitors manufactured to ±5% MFD tolerance and tested to 60,000 service hours. Generic capacitors often run at ±10% tolerance, accelerating motor wear and reducing compressor life — especially critical on a 4-ton packaged unit running in high-ambient conditions.
  • Install Difficulty: 2/5 — Always disconnect and lock out power before servicing. Discharge the capacitor terminals using an insulated screwdriver or bleed resistor before touching leads. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting. Match the MFD rating exactly — never substitute a different value.
  • Warranty & Shipping: 1-year OEM factory warranty against defects. Ships same business day from our warehouse. Verify the MFD and voltage rating on your unit's wiring diagram or data plate before ordering — the PY1PEB048115AAAA uses all three capacitors listed; order the specific rating for the motor circuit you are replacing.

Compatibility: Fits Carrier model PY1PEB048115AAAA packaged gas/electric unit (4-ton, 115 MBH gas heat). Cross-references: HC90AA004, HC91CA004, HC91CA010, HC91CA015, GE/Genteq C304L (27L571), C310L (27L669), C315L (27L567). Questions about which capacitor rating your specific motor circuit requires?

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PEB048115AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PEB048115AAAA. 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 PY1PEB048115AAAA?
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.
