OEM Carrier Single Run Capacitor 10 MFD 370V for Model PY1PPA048100AGBA

This is the OEM-specified single run capacitor for the Carrier PY1PPA048100AGBA packaged heating and cooling unit. Cross-referenced under part numbers HC30GB230 (Draft Inducer Motor w/ Capacitor assembly) and P291-1003 (Single Run Capacitor), this oval-style capacitor powers the draft inducer motor—the critical component responsible for venting combustion gases safely out of the heat exchanger. When this capacitor weakens or fails, you'll notice symptoms including a humming inducer motor that won't spin up to speed, a furnace that locks out before ignition, or a pressure switch fault code because the inducer never reaches full CFM. Replacing the capacitor first is the correct low-cost diagnostic step before condemning the entire inducer motor assembly.

• Specs: 10 MFD (microfarad) | 370–440V rated | Oval case | ±5–6% factory tolerance | 50/60 Hz | UL-approved current interrupter | Non-PCB dielectric fluid
• OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerance, ensuring the inducer motor receives the precise starting torque specified for the PY1PPA048100AGBA. Off-brand capacitors with loose ±10% tolerance can cause nuisance pressure switch faults and premature inducer motor bearing wear.
• Install difficulty: 1/5 — One of the simplest furnace repairs available. Tools needed: flathead screwdriver or needle-nose pliers to remove the spade terminals, and a multimeter to verify the failed unit reads below spec. Always shut off power at the disconnect and verify 0V before touching any terminals.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PY1PPA048100AGBA packaged unit. Note: P291-1003 has been superseded by P291-1004 (440V-rated upgrade); both are direct drop-in replacements.
