OEM Carrier Dual Run Capacitor P291-6073RS for Model HB1BJX048000AAAA

This OEM dual run capacitor (part number P291-6073RS) is the factory-specified replacement for the Carrier HB1BJX048000AAAA packaged or split-system unit. The dual run capacitor serves a critical role in your HVAC system — it stores and delivers the electrical charge required to start and continuously run both the compressor and the condenser fan motor. When this component fails, common symptoms include a loud humming noise with no motor movement, the system short-cycling within the first few minutes of operation, or the condenser fan spinning slowly or not at all. Left unaddressed, a failing capacitor places extreme stress on the compressor, potentially leading to costly compressor replacement.

  • Specs: OEM part number P291-6073RS | Dual run configuration | Factory-matched MFD rating and 370V/440V voltage rating | Round case design | ±3% tolerance for precise motor protection
  • OEM vs Generic: This is a genuine OEM Carrier capacitor engineered to exact factory specifications. Generic aftermarket capacitors frequently operate at ±10% MFD tolerance, which accelerates motor winding wear, increases compressor stress, and shortens the overall service life of your system.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals to avoid serious electrical shock. Recommended tools: 1/4" nut driver, needle-nose pliers, insulated screwdriver, and a multimeter to verify discharge. Photograph all wiring connections before removing the old unit to ensure correct reinstallation.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships the same business day from our warehouse so your system is back up and running fast.

Compatibility: Designed for the Carrier HB1BJX048000AAAA unit. Always verify the MFD and voltage ratings printed on your existing capacitor's label or your unit's data plate before ordering to confirm an exact match. Not sure if this is the right part? Our HVAC parts specialists are available to verify fitment before you order — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier HB1BJX048000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier HB1BJX048000AAAA. 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 HB1BJX048000AAAA?
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.
