OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PF4MNA024T00AAAA

This is the factory-specified OEM replacement single run capacitor for the Carrier PF4MNA024T00AAAA fan coil and air handler system. Rated at 7.5 MFD (microfarad) at 370V, this oval-style capacitor is responsible for sustaining the continuous operation of the blower or fan motor. When this capacitor degrades or fails, you'll typically notice symptoms such as a humming motor that won't spin up, intermittent motor starting, or the system shutting off shortly after startup due to motor overload. Replacing it promptly prevents secondary damage to the motor windings.

• Specs: 7.5 MFD (µF) | 370V rated (440V-compatible replacement acceptable) | Oval case | OEM part number P291-0753 | Cross-references: HC91CA007, GE/Genteq 27L566 (C307L)
• OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory MFD tolerance (±5%), ensuring stable motor performance and longevity. Generic aftermarket units commonly run at ±10% or wider tolerances, which can accelerate motor wear over time.
• Install Difficulty: 1/5 — This is one of the simplest HVAC repairs. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (to verify capacitance before and after). Always discharge the old capacitor by bridging terminals with an insulated screwdriver before handling, and photograph all wiring connections prior to removal.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
