OEM Carrier Single Run Capacitor 15 MFD 370V for Model PH1RPA048000AAWB

This OEM single run capacitor is the factory-specified replacement for the Carrier PH1RPA048000AAWB heat pump system, sold under Carrier part number P291-1503 (superseded by P291-1504). The run capacitor provides a continuous phase-shifted current to keep the fan motor or compressor running smoothly after startup. A failing run capacitor typically causes the motor to hum without spinning, draw excessive amperage, overheat, or cause the system to short-cycle and trip on thermal overload.

  • Specs: 15 MFD (microfarad) ±5% | 370V AC rated | Oval case | 50/60 Hz | UL-approved current interrupter | Non-PCB dielectric fluid
  • OEM vs Generic: This is the genuine OEM Totaline/Carrier capacitor meeting exact factory tolerance. Generic replacements often run ±10% MFD deviation, which accelerates motor winding stress and shortens component life. Note: Carrier sources capacitors from third-party manufacturers — the capacitor label will show the manufacturer name, not Carrier.
  • Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before removal.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM ship same business day from our warehouse.

Compatibility: Designed for the Carrier PH1RPA048000AAWB heat pump system. This part number (P291-1503) has been superseded by P291-1504 — our listing ships the current active replacement. Always verify the MFD rating and voltage on your unit's data plate before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH1RPA048000AAWB?
Yes. This is the factory-specified OEM capacitor for the Carrier PH1RPA048000AAWB. 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 PH1RPA048000AAWB?
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.
