OEM Carrier Run Capacitor Replacement for Furnace PG9MAA048080AEKA

The run capacitor stores and delivers the phase-shifted jolt of electricity that keeps your furnace's blower motor spinning smoothly through every heat and cool call. When it weakens or fails, the motor struggles to start or hold speed — you'll hear a steady humming or buzzing at the air handler, notice weak airflow from the registers, catch a hot-electrical odor, or find the blower dead while the furnace overheats and trips on its high-limit switch. A failing capacitor also forces the motor to draw excess amperage, which slowly cooks the windings if it isn't replaced. This is an OEM-spec run capacitor matched to the microfarad (MFD/µF) and voltage rating Carrier engineered for this blower motor — typically a 370V or 440V oil-filled metallized polypropylene cap held to a tight ±5% MFD tolerance. Always confirm the MFD and voltage stamped on your old capacitor or the unit data plate before ordering. MFD tolerance is everything with capacitors. An OEM cap holds ±5%, so the motor receives the exact phase shift it was designed for. Cheap aftermarket caps drift to ±10–15% and use lower-temperature dielectrics; the wrong MFD overdrives or starves the windings, raises operating temperature, and shortens motor life — turning a cheap part into a costly motor replacement. Install difficulty: 2/5. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify MFD. SAFETY: a charged capacitor holds a lethal shock even with the power off — kill the breaker and discharge the terminals with an insulated screwdriver laid across them before touching any wiring. Ships same business day from our stocked U.S. warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PG9MAA048080AEKA. 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.
