OEM Carrier Round Dual Run Capacitor for PY3PEA048115NA Furnace

The run capacitor provides the constant phase shift that keeps your blower motor (and on packaged units, the compressor and condenser fan) spinning efficiently. It stores and releases energy on every cycle to keep the motor's start and run windings in proper phase. When a capacitor weakens or fails, you'll hear a loud hum from the motor that struggles to start, notice warm or weak airflow, see the breaker trip, or find a motor that gets hot and cuts out on its thermal overload. A bulged or leaking top is a sure sign of failure, but many capacitors drop in value silently while overworking the motor. This is the genuine Carrier round dual run capacitor. Match the printed MFD (microfarad) rating and voltage — typically 370V or 440V on this platform — exactly to your old part. OEM capacitors are built to a tight ±5% tolerance, so a 45 MFD section actually delivers 45 MFD across its rated temperature range. OEM matters because capacitor value directly controls motor torque and current. Generic aftermarket capacitors often carry ±10–15% tolerance and lower-grade dielectric film, so a capacitor labeled 45 MFD may actually deliver 38 — that wrong value stresses the motor windings, raises amp draw, and shortens compressor and blower life. The genuine part protects the expensive motor it serves. Install difficulty: 1/5. Tools needed: 1/4" nut driver, insulated screwdriver, and a multimeter with capacitance mode. #1 safety warning: a charged capacitor can deliver a dangerous shock — discharge it by bridging the terminals with an insulated screwdriver after killing power, before disconnecting any wires.

Compatibility

This part is compatible with Carrier model PY3PEA048115NA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

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.

Shipping & Returns

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.
