OEM Carrier Dual Run Capacitor for PG8MAA066110ABJA Gas Furnace

The run capacitor in your Carrier PG8MAA066110ABJA stores and releases electrical energy to keep the blower motor (and, on packaged units, the condenser fan and compressor) spinning efficiently. It provides the continuous phase shift these single-phase motors need to run smoothly. As the capacitor weakens, its stored charge drops and the motor struggles to start and hold speed. Homeowners typically notice a loud humming from the furnace or condenser, a fan that hesitates or won't start, warm air instead of cool, breakers that trip, and motors that run hot and short-cycle on thermal overload. A bulged or leaking top on the capacitor is a sure sign it has failed. This is a dual-rated run capacitor measured in microfarads (MFD/µF) at a specific voltage — typically 370V or 440V on Carrier packaged equipment. OEM capacitors are held to a tight ±5% tolerance, so a 45/5 MFD unit delivers very close to its rated value across its service life and operating temperature. Why OEM matters here: cheap aftermarket capacitors often carry ±10-15% tolerance and lower-grade dielectric film. A capacitor even a few MFD out of spec forces the motor to draw extra current, overheating compressor and blower windings and dramatically shortening their life. Undersized voltage ratings also fail early in hot attic and rooftop installations. Install difficulty: 2 of 5. Tools: 1/4" nut driver, needle-nose pliers, and a multimeter with a capacitance setting to verify MFD. SAFETY — capacitors hold a lethal charge even with power off: ALWAYS discharge the terminals through an insulated resistor or screwdriver before touching them, and kill the breaker first.

Compatibility

This part is compatible with Carrier model PG8MAA066110ABJA. 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.
