OEM Carrier Draft Inducer Single Run Capacitor 4 MFD 370V for Model PY1RPA060115AAWB

This is the factory-specified OEM single run capacitor for the draft inducer motor in the Carrier PY1RPA060115AAWB furnace. Cross-referenced under OEM part numbers HC30GB230 and P291-0403, this oval 4 MFD 370V capacitor is dedicated to sustaining the inducer motor's run winding during normal furnace operation. When the inducer motor capacitor fails, the furnace will typically attempt to start, fail to prove proper venting, and lock out — triggering a pressure switch fault code. In some cases, the inducer motor hums but does not spin, or intermittently drops out mid-heating cycle.

• Specs: 4 MFD (microfarad) | 370V AC rated | Oval case | Single-section run capacitor | 50/60 Hz | OEM part numbers: HC30GB230, P291-0403
• OEM vs Generic: This OEM unit is factory-matched to the Carrier PY1RPA060115AAWB inducer motor's exact capacitance tolerance (±5%). Generic capacitors often run ±10–15% MFD, which can cause the inducer motor to overheat, underperform, and fail prematurely — especially at low ambient temperatures during winter startup.
• Install difficulty: 2/5 — Discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver or flat-head screwdriver, needle-nose pliers, multimeter (capacitance mode). Always photograph the original wiring before disconnecting. Capacitor is typically located on or adjacent to the inducer motor housing inside the blower compartment.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY1RPA060115AAWB furnace draft inducer motor assembly. Note that P291-0403 has been superseded — verify your unit's data plate and existing capacitor MFD and voltage ratings before ordering.
