OEM Carrier Dual Run Capacitor for Package Unit PY1REA120180ABWB

The dual run capacitor is the electrical heart of your Carrier PY1REA120180ABWB package unit, delivering the phase-shifted jolt that both the compressor (HERM) and the outdoor condenser fan motor (FAN) need to start and keep running efficiently from a single can. When it weakens or fails, you'll see the most common service-call symptoms in the field: the unit hums but won't start, the outdoor fan turns slowly or not at all, the compressor short-cycles or trips the breaker, and on a hot afternoon the system blows warm air while the contactor chatters. A bulging top or oily leak on the can is a dead giveaway. Specs: This OEM dual run capacitor matches the factory MFD and voltage ratings for the PY1REA120180ABWB (commonly a combined value such as 45/5 MFD at 440 VAC — verify against your unit's data plate). It holds a tight ±5% capacitance tolerance and is rated for 70°C operation with a 10,000-hour service life, exactly as Carrier specified. OEM vs Generic: Capacitor tolerance is not a detail you can compromise. Generic aftermarket cans often ship at ±10-15%, and a capacitor reading even 10% low under-energizes the compressor start windings, raising amp draw, heat, and the risk of an early compressor burnout — a failure that costs far more than a lifetime of capacitors. OEM holds the rating that protects your compressor. Install: Difficulty 2 of 5. Tools: 1/4-inch and 5/16-inch nut driver, insulated needle-nose pliers, and a multimeter to confirm the new reading. #1 safety warning: a charged capacitor stores a dangerous shock — kill the breaker AND discharge the capacitor across each terminal pair with an insulated screwdriver before touching any wires. 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

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.
