OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PPA048120AFBA

This is the OEM-specified single run capacitor for the draft inducer motor assembly on the Carrier PY1PPA048120AFBA packaged unit. Cross-referenced under primary assembly part number HC30GB230 and discrete capacitor part number P291-1003, this capacitor provides the continuous run voltage that keeps the inducer blower motor spinning at proper speed throughout every heating cycle. When this capacitor weakens or fails, the draft inducer motor will hum without starting, run erratically, or cause the furnace to lock out on a pressure switch fault — symptoms often misdiagnosed as a failed motor or faulty pressure switch.

• Specs: 4 MFD (microfarad) | 370VAC rated | Single run capacitor | Factory-matched tolerance for inducer motor HC30GB230 | OEM part numbers: HC30GB230 (assembly), P291-1003 (capacitor)
• OEM vs Generic: This OEM capacitor is manufactured to exact Carrier factory tolerances (±3% MFD). Generic capacitors often carry a ±10% tolerance, which can cause the inducer motor to run hot, shorten motor life, and void equipment warranties.
• Install difficulty: 2/5 — Disconnect power and allow capacitor to discharge fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify capacitance). Photograph existing wiring before disconnecting terminals. Always confirm MFD and voltage ratings on the original capacitor before installation.
• Warranty: 1-year OEM factory warranty on parts. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Designed for the Carrier PY1PPA048120AFBA packaged unit equipped with the HC30GB230 draft inducer motor assembly. Verify the 4 MFD and 370V ratings against your existing capacitor's data label before ordering. Not sure it fits? Our HVAC parts specialists will verify fitment before you purchase — no guesswork required.
