OEM Carrier Single Run Capacitor 5 MFD 370V for Model PG9MAB036040ABSA

This is the genuine OEM Carrier single run capacitor (part number P291-0503) factory-specified for the Carrier PG9MAB036040ABSA gas furnace. The run capacitor provides the sustained electrical charge needed to keep the indoor blower motor spinning at rated torque and efficiency. When this capacitor weakens or fails, you'll typically notice the blower motor humming without starting, running sluggishly, drawing excess current, or shutting off intermittently — all of which can lead to overheating and premature motor failure if left unaddressed.

  • Specs: 5 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | CBB65-V type | 50/60 Hz | Factory-matched ±6% tolerance
  • OEM vs Generic: This genuine Carrier/Totaline OEM capacitor is manufactured to exact factory tolerances. Generic capacitors often carry ±10% MFD variance, which accelerates blower motor wear and can cause nuisance faults or repeat failures.
  • Install difficulty: 2/5 — Always discharge the capacitor terminals before removal using an insulated resistor or discharge tool. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old capacitor.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse in original factory packaging.

Compatibility: Designed as the direct factory replacement for Carrier model PG9MAB036040ABSA gas furnaces. Note: P291-0503 has been superseded by P291-0504 — both are fully interchangeable at the same 5 MFD / 370V specification. Always verify the MFD and voltage rating on your unit's data plate before ordering. Our team is available to confirm fitment prior to purchase.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG9MAB036040ABSA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG9MAB036040ABSA. 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 PG9MAB036040ABSA?
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.
