OEM Carrier Single Run Capacitor P291-1003 for Model PF1MNC030000AAAA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PF1MNC030000AAAA fan coil and associated condensing equipment. A single run capacitor maintains a continuous phase-shift in the motor winding to keep the motor running at rated torque and efficiency. When it degrades or fails, common symptoms include a loud humming with no motor movement, intermittent motor start failures, or the system tripping on thermal overload shortly after startup.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Round hermetically sealed case | ±5% tolerance per OEM specification — verify exact MFD on your unit data plate before ordering
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances. Generic alternatives often deviate ±10% MFD, which accelerates motor winding wear, reduces efficiency, and can shorten compressor or fan motor life significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before removing terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting anything.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our climate-controlled warehouse — arrive faster, fix faster.

Compatibility: Designed specifically for the Carrier PF1MNC030000AAAA. Always cross-reference the MFD rating and voltage on your unit's data plate to confirm an exact match prior to installation. Our HVAC parts specialists are available to verify fitment before you order — no guesswork, no return hassles.
