OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PPA060090AA

This is the factory-specified OEM single run capacitor for the Carrier PY3PPA060090AA packaged rooftop unit. The run capacitor stores and releases electrical energy to keep the fan motor running smoothly and efficiently throughout each cooling or heating cycle. When this capacitor weakens or fails, you'll notice symptoms such as a fan motor that hums but won't spin, a motor that overheats and trips on thermal overload, or a unit that short-cycles and fails to maintain setpoint — all signs it's time for an immediate replacement.

• Specs: 4 MFD (microfarad) | 370 VAC | Oval case | OEM part numbers: P291-0403 / P291-2503 | Also replaces: HC90AA004, HC91CA004, 97F5704
• OEM Quality Advantage: Built to Carrier factory tolerances with high-grade metallized polypropylene film, UL-approved pressure-sensitive interrupter, and 100% electrical testing. Generic capacitors often run out of spec, accelerating motor wear and voiding equipment warranties.
• Install Difficulty: 1/5 — One of the easiest HVAC repairs. Shut off power at the disconnect, wait 5 minutes for the capacitor to fully discharge, photograph existing wiring, swap terminals one at a time, and restore power. Tools needed: flathead or 1/4" nut driver, needle-nose pliers, and a multimeter to verify capacitance before and after.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time to go out today.
