OEM Carrier Single Run Capacitor 7.5 MFD 440V for Model TJACCY50DP900111

This is the genuine OEM single run capacitor (P291-0754) factory-specified for the Carrier TJACCY50DP900111 packaged HVAC unit. The run capacitor stores and delivers the precise electrical charge required to start and sustain the blower motor during every cooling and heating cycle. When this component degrades or fails, the blower motor may become audibly noisy, overheat under load, run sluggishly, or stop operating entirely — leaving your system unable to move conditioned air through the ductwork.

• Specs: 7.5 MFD (µF) | ±6% tolerance | 370/440VAC dual-rated | 50/60 Hz | Oval case (CBB65A) | Factory OEM part number P291-0754
• OEM vs Generic: This is a genuine Carrier (Totaline) OEM capacitor, manufactured to exact factory tolerances. Aftermarket capacitors often carry a wider ±10% MFD tolerance, which increases motor stress, reduces efficiency, and shortens the service life of both the motor and the capacitor itself.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify discharge. Photograph all wire connections before removal. Observe correct terminal orientation on reinstallation.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse when ordered before the daily cutoff.
