OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1RPA060074AAWB

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1RPA060074AAWB packaged unit's draft inducer motor circuit. Sourced under Carrier OEM part numbers P291-0403 and HC30GB230, this oval 4 MFD 370V capacitor provides the sustained electrical charge that keeps the inducer motor spinning at proper speed. When this capacitor degrades or fails, the draft inducer motor may hum without starting, run erratically, or fail to prove airflow — triggering a pressure switch lockout and a no-heat condition.

• Specs: 4 MFD (microfarad) | 370V AC rated | Oval case | Single run capacitor | 50/60 Hz | Factory-matched tolerance
• OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor — tested to 60,000 service hours with UL-approved pressure-sensitive interrupter protection. Generic capacitors often run outside tolerance, accelerating inducer motor wear and triggering nuisance lockouts.
• Install difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring before disconnecting. Verify MFD and voltage ratings against the motor data plate before installation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PY1RPA060074AAWB packaged units. Also cross-references OEM part numbers P291-0403 and HC30GB230. Supersedes HC90AA004, HC91CA004, HC90AB004, HC96FG004, HC96FU004, and HC97CF004. Verify 4 MFD and 370V ratings on your unit's capacitor data label before ordering. Our team is available to confirm fitment prior to purchase.
