OEM Carrier Single Run Capacitor 30 MFD 440V for Model 09DE146C100

This OEM single run capacitor (Totaline P291-3004) is the factory-specified replacement for the Carrier 09DE146C100. The run capacitor maintains a continuous phase-shifted current to keep the motor running smoothly after startup. A failed or weak capacitor is one of the most common HVAC service calls — symptoms include a loud hum with no motor movement, intermittent short-cycling, or the unit tripping on thermal overload shortly after startup.

• Specs: 30 MFD (microfarad) | 440V rated | Oval case | Factory-matched ±5% tolerance | 50/60 Hz | Non-PCB dielectric fluid
• OEM vs Generic: This is the genuine Totaline OEM capacitor sourced directly from Carrier's supply chain. OEM units are manufactured to exact factory tolerance, ensuring reliable motor protection and full rated service life. Generic aftermarket capacitors often carry ±10% MFD variance, which accelerates motor winding stress and reduces compressor longevity.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling — use an insulated resistor or discharge tool across the terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph existing wiring before disconnecting terminals. Installation takes approximately 15–20 minutes.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model 09DE146C100. Always verify the MFD rating and voltage printed on your existing capacitor's data label before ordering to confirm fitment. Need help? Our HVAC parts specialists verify compatibility before you order — reach out via chat or phone.
