The run capacitor gives your Carrier compressor and condenser fan motor the steady phase shift they need to run efficiently after start-up. As it weakens, it can no longer hold the proper charge, and the motors struggle. When a run capacitor fails you'll hear a loud hum from the outdoor unit with no fan rotation, the compressor tries to start and trips the breaker, the AC blows warm air, or you'll see a bulged or leaking top on the old capacitor. Failed capacitors are the single most common no-cooling cause in summer. This OEM run capacitor is rated to Carrier's exact MFD (microfarad) and voltage values — typically 370V or 440VAC — and holds a tight ±5% tolerance so the motor receives the precise running torque it was engineered for. Correct capacitance keeps amp draw and operating temperature in spec. Why OEM matters here: generic capacitors often ship with ±10–15% tolerance and lower-grade dielectric film, so even a 'matching' MFD can drift out of range. The wrong capacitance forces the compressor windings to run hotter and draw more current, shortening compressor life and risking a far more expensive failure. The OEM part holds rating under heat and time. Installation difficulty: 2/5. Tools needed: a 1/4" and 5/16" nut driver, an insulated screwdriver, a multimeter with capacitance mode, and needle-nose pliers; photograph the terminals (HERM/FAN/C) first. #1 safety warning: a capacitor stores a lethal charge — discharge it across the terminals with an insulated resistor and cut power at the disconnect and breaker before touching it. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.
This part is compatible with Carrier model YAC60140YAC101C. Always verify the part number against your unit's data plate before ordering.
OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
