OEM Carrier Single Run Capacitor 7.5 MFD 370V — P291-0753 for Model PF1MNC018005AAAA

This is the factory-specified OEM single run capacitor for the Carrier PF1MNC018005AAAA fan coil and air handler system. Rated at 7.5 MFD (microfarad) at 370 VAC in an oval case, this capacitor provides the continuous electrical charge required to keep the blower or fan motor running at proper efficiency. When it begins to fail, you'll notice symptoms such as a humming motor that won't start, sluggish fan spin-up, intermittent shutdowns, or a complete motor no-start condition — all of which can quickly lead to overheating and secondary motor damage if left unaddressed.

• Specs: 7.5 MFD (µF) | 370 VAC rated | Oval case form factor | ±5% factory tolerance | Cross-references: HC91CA007, GE/Genteq 27L566 (C307L)
• OEM vs Generic: This OEM Carrier capacitor is built to exact factory tolerances. Generic replacements commonly run ±10% MFD deviation, which increases motor amp draw, accelerates winding wear, and shortens component life — especially critical in a sealed air handler environment.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Disconnect power at the breaker. Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old capacitor.
• Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
