The run capacitor stores and releases electrical energy to keep the compressor and condenser fan motor running smoothly and efficiently. As it ages, its capacitance drifts and it loses the ability to deliver the phase shift those motors depend on. Homeowners notice a humming outdoor unit whose fan won't start, a compressor that buzzes and trips the breaker, warm air from the vents, hard starting or clicking, and creeping electric bills as the motors draw excess current. A weak capacitor forces motors to run hot, dramatically shortening their life — a $20 part left failing can kill a compressor. This OEM run capacitor is rated to the exact microfarad (MFD/µF) and voltage your motors require — commonly a dual round capacitor such as 35/5 MFD at 370 or 440 VAC with HERM (compressor) and FAN terminals — though you must match the rating stamped on your existing capacitor. OEM capacitors hold a tight ±5% tolerance and use 10,000-hour-rated film dielectric for long, stable service in high heat. Capacitance is everything here. Generic capacitors often carry ±10-15% tolerance, so a labeled "35 MFD" part may actually deliver 30 or 40 — either way the motor runs off its design point, drawing more current and overheating its windings. Under-rated voltage or cheap dielectric bulges and fails in the first hot summer. The OEM part's tight tolerance and high-temperature film keep your compressor and fan motor within spec. Install difficulty: 2/5. Tools: insulated screwdriver, 1/4" nut driver, and a multimeter with capacitance (MFD) mode. #1 safety warning: a charged capacitor holds a dangerous, potentially lethal voltage — kill the disconnect and breaker, then discharge it across its terminals with an insulated-handle screwdriver before touching it. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.
This part is compatible with Carrier model PY1PNA060100AEBA. Always verify the part number against your unit's data plate before ordering.
OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
