OEM Carrier Single Run Capacitor 5 MFD 370V for Model PG9MAB036060LBSA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAB036060LBSA gas furnace. The run capacitor provides the sustained electrical charge required to keep the indoor blower motor running at full efficiency. When this capacitor degrades or fails, the blower motor may struggle to start, run intermittently, overheat, or stop altogether — resulting in poor airflow, uneven heating, or a system lockout fault. Replacing a failing run capacitor promptly protects the blower motor from burnout and avoids a far more costly repair.

  • Specs: 5 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | 50/60 Hz | OEM Part # P291-0503 (superseded by P291-0504) | Cross-references: P2910503, 97F5705
  • OEM vs Generic: This OEM-spec capacitor is manufactured to exact Carrier factory tolerances (±5% MFD). Generic aftermarket capacitors often carry a wider ±10% tolerance, which accelerates blower motor wear and can shorten motor life — especially in high-run-time furnace applications.
  • Install Difficulty: 2/5 — Always discharge the capacitor before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify discharge and confirm MFD rating). Photograph all wiring connections before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAB036060LBSA gas furnace indoor blower motor circuit. Always verify the MFD and voltage rating on your existing capacitor's data label before ordering. Cross-reference OEM part numbers P291-0503 and P291-0504. Need help confirming fitment? Our HVAC parts specialists verify compatibility before every order — contact us today and get your furnace back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG9MAB036060LBSA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG9MAB036060LBSA. 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 PG9MAB036060LBSA?
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.
