The run capacitor gives both the compressor and the condenser fan motor the phase-shifted jolt of stored energy they need to start turning and to keep running efficiently. As it weakens, the motors struggle to draw their rated current. Homeowners typically notice a hard hum from the outdoor unit that won't start spinning, fans or compressors that need a manual push to begin, short-cycling, warm air from the vents, or the breaker tripping. A failing capacitor often shows a bulged or domed top and may leak oil — a sure sign it's done. This is a dual-round run capacitor, commonly rated around 35/5 MFD at 370/440V, with HERM and FAN terminals feeding the compressor and fan motor respectively. OEM specification holds a tight ±5% tolerance and a 10,000-hour insulation rating. Match the exact MFD values and voltage stamped on the old can — voltage may be equal or higher, but MFD must match. Why OEM matters: capacitor performance lives or dies on tolerance. Cheap aftermarket capacitors are often built to ±10–15%, so a 35 MFD can may actually deliver 30 or 40. Wrong capacitance starves or overdrives the compressor windings, causing overheating, increased amp draw, and premature compressor failure — by far the most expensive part in the system. A tight-tolerance OEM cap protects that compressor. Install difficulty: 2/5. Tools needed: 1/4" nut driver, needle-nose pliers, a multimeter with capacitance mode, and an insulated screwdriver. #1 safety warning: a charged capacitor stores a lethal jolt even with power off — kill the breaker and discharge the capacitor across all terminals with an insulated resistor before disconnecting a single wire. Photograph the wiring first. 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 PY1PPB036060NBAA. 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.
