OEM Carrier Single Run Capacitor P291-1503 for Model G2RR125C20

This is the genuine OEM single run capacitor (part number P291-1503) factory-specified for the Carrier G2RR125C20 system. A single run capacitor provides the continuous electrical charge required to keep the motor running after startup — whether that's the condenser fan motor or the compressor. When this component fails, you'll notice symptoms such as a humming unit that won't start, a motor that runs hot and shuts off on thermal overload, or a system that trips the breaker shortly after startup. Replacing a failed run capacitor promptly prevents secondary damage to motors and compressors, which are far more costly to replace.

  • Specs: Single run capacitor | OEM part number P291-1503 | Factory-matched MFD and voltage rating | Round case design | ±5% tolerance for precise motor protection
  • OEM vs Generic: This is a genuine Carrier OEM capacitor, not an aftermarket substitute. OEM units are manufactured to exact factory tolerances, ensuring proper motor run current and extended service life. Generic capacitors often carry ±10% MFD tolerances that can accelerate motor winding wear over time.
  • Install Difficulty: 2/5 — A single run capacitor is one of the more straightforward HVAC repairs. Required tools: 1/4" nut driver, insulated needle-nose pliers, and a multimeter capable of capacitance testing. Always discharge the capacitor fully before handling terminals, and photograph all wiring connections before removal.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed specifically for the Carrier G2RR125C20. Before ordering, verify the MFD and voltage ratings printed on your existing capacitor or on the unit's data plate to confirm this part matches your system's exact specification. Our HVAC parts specialists are available to verify fitment — contact us before you order if you have any questions. Orders placed today ship same business day.

Frequently Asked Questions

Does this Capacitor fit my Carrier G2RR125C20?
Yes. This is the factory-specified OEM capacitor for the Carrier G2RR125C20. 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 G2RR125C20?
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.
