OEM Carrier Single Run Capacitor 3 MFD 250V — HC91PD001 for Model PG9MAA036040AEKA

This genuine OEM Carrier single run capacitor (part number HC91PD001) is the factory-specified replacement for the Carrier PG9MAA036040AEKA gas furnace. The run capacitor provides the sustained electrical charge required to keep the inducer draft motor spinning at proper speed throughout the heating cycle. When this capacitor weakens or fails, the inducer motor may hum, struggle to start, or fail to run entirely — causing the furnace to lock out before ignition ever occurs.

• Specs: 3 MFD (microfarad) | 250 VAC rated | Rectangular form factor | CSA listed | 50/60 Hz compatible | Factory-matched tolerance for precise motor performance
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not a knockoff. Generic capacitors are often rated at loose tolerances (±10% or worse), which causes the inducer motor to run hot, shortens motor life, and can trigger nuisance pressure switch faults. OEM means exact-fit, exact-spec, every time.
• Install Difficulty: 2/5 — Safe for confident DIYers. Always shut off power at the breaker before beginning. Discharge the capacitor using an insulated resistor or screwdriver across the terminals before handling. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter (to verify capacitance). Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PG9MAA036040AEKA gas furnace with inducer motor requiring a 3 MFD 250V rectangular run capacitor. Also used across a wide range of Carrier, Bryant, and Payne gas furnace platforms sharing the same inducer motor specification — verify MFD and voltage ratings on your existing capacitor or equipment data plate before ordering.
