OEM Carrier Single Run Capacitor 7.5 MFD 440V for Model TJACCYCRPWREXH008A10

This OEM Totaline by Carrier single run capacitor (part# P291-0754) is the factory-specified replacement for the Carrier TJACCYCRPWREXH008A10 system. The run capacitor stores and releases the precise electrical charge needed to start and sustain the blower or fan motor throughout its operating cycle. When this component fails, you may notice the motor humming without turning, the blower overheating and shutting down prematurely, or the unit failing to run altogether — common symptoms that point directly to a failed run capacitor.

  • Specs: 7.5 MFD (microfarads) | 440V AC rated | Oval form factor | ±6% capacitance tolerance | 50/60 Hz compatible | UL approved & RoHS compliant
  • OEM vs Generic: This is the genuine Totaline by Carrier OEM part, engineered to exact factory specifications. Generic alternatives often carry a wider tolerance (±10% or more), which can accelerate motor wear and reduce component lifespan. OEM ensures a precise match every time.
  • Install difficulty: 1/5 — One of the simplest HVAC repairs available. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (recommended to verify discharge). Always discharge the old capacitor before handling and photograph existing wiring before disconnecting.
  • Warranty: 1-year OEM warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model TJACCYCRPWREXH008A10. Also replaces superseded part numbers P291-0753 and HC91CA007. Always verify the MFD and voltage rating on your unit's data plate before ordering to ensure a proper match. Have questions about fitment? Our HVAC parts specialists confirm compatibility before you buy — reach out before placing your order.

Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 7.5 MFD 440V — TJACCYCRPWREXH008A10. 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 OEM Carrier Single Run Capacitor 7.5 MFD 440V — TJACCYCRPWREXH008A10?
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.
