OEM Carrier Totaline Single Run Capacitor 370V for Model PY2PEB048090AA

These genuine Carrier Totaline single run capacitors are the factory-specified replacements for the Carrier PY2PEB048090AA packaged unit. A run capacitor stays in the circuit continuously while the compressor or fan motor operates, stabilizing voltage and ensuring efficient motor performance. When a run capacitor weakens or fails, you'll notice symptoms such as a humming or buzzing with no motor movement, the system blowing warm air, short-cycling, or a complete no-start condition. Replacing the failed capacitor with the correct OEM-rated unit restores proper motor torque and prevents premature compressor wear.

  • Specs & Part Numbers: P291-0403 — 4 MFD | 370V | Oval | For inducer/secondary motor circuits  |  P291-1003 — 10 MFD | 370V | Oval | For condenser fan motor  |  P291-1503 — 15 MFD | 370V | Oval | For compressor run circuit. All three are Oval case, 370 VAC rated, 50/60 Hz compatible.
  • OEM vs Generic: Genuine Carrier Totaline capacitors are factory-tolerance matched (±5% MFD) and reliability-tested to 60,000 service hours. Generic aftermarket capacitors often carry a ±10% tolerance, which accelerates motor wear, increases heat buildup, and shortens compressor service life.
  • Install Difficulty: 2/5 — Always disconnect power at the disconnect box and wait at least 5 minutes for the capacitor to self-discharge before touching any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removing the old capacitor. Match replacement MFD and voltage to the failed unit — do not substitute a higher or lower MFD rating.
  • Warranty & Shipping: 1-year OEM factory warranty. Ships same business day from our warehouse. Verify which MFD rating is needed by cross-referencing the part number on the failed capacitor or the equipment data plate on your PY2PEB048090AA unit.

Compatibility: Designed for use in the Carrier PY2PEB048090AA packaged gas/electric unit. Cross-references include HC90AA004 (P291-0403), HC91CA010 (P291-1003), and HC90AA015 / HC91CA015 (P291-1503). Carrier sources these capacitors from Totaline, its replacement components division — the writing on the capacitor body will reflect the capacitor manufacturer's name, not Carrier. Always verify the MFD rating on your failed part before ordering. Questions? Our HVAC parts team confirms fitment before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 4/10/15 MFD 370V — PY2PEB048090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 4/10/15 MFD 370V — PY2PEB048090AA. 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 OEM Carrier Single Run Capacitor 4/10/15 MFD 370V — PY2PEB048090AA?
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?
