OEM Payne Run Capacitor for PA4ZNA036000AA AC Condenser Unit

The run capacitor in your Payne PA4ZNA036000AA condensing unit stores and releases a precise phase-shifted electrical charge that keeps the compressor and condenser fan motor spinning at full torque every second they run. When it weakens or fails, you'll notice the classic symptoms: the outdoor unit hums but the fan won't spin, the compressor tries to start and trips the breaker, the system short-cycles, or warm air blows from the registers on the hottest afternoon. A swollen, leaking, or bulging top cap is a dead giveaway it's time to replace it. This is a dual-run capacitor rated for both the compressor (HERM) and fan (FAN) terminals, typically supplied in the 35/5 to 45/5 MFD range at 440 VAC for this tonnage. The critical spec is microfarad (MFD) capacitance, and a genuine OEM unit holds a tight ±5% tolerance so the motor windings see exactly the charge they were engineered for. Why OEM matters here: cheap aftermarket capacitors often run ±10–15% tolerance and use thinner foil and lower-grade dielectric. A capacitor that drifts out of spec forces the compressor windings to draw excess amperage, overheat, and fail years early — turning a $30 part into a $1,800 compressor replacement. OEM specification protects the most expensive component in your system. Installation difficulty: 2 of 5. Tools needed: 1/4" nut driver, insulated flathead screwdriver, and a multimeter to confirm the failed reading. SAFETY — capacitors hold a lethal charge even with power off: kill the disconnect AND discharge the capacitor across the terminals with an insulated screwdriver before touching any 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.

Compatibility

This part is compatible with Payne model PA4ZNA036000AA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

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.

Shipping & Returns

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.
