OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PEB036090ABAA

This is the factory-specified OEM single run capacitor for the Carrier PY1PEB036090ABAA packaged unit. The run capacitor provides the continuous phase-shifted current required to keep the condenser fan motor or blower motor spinning efficiently once started. When this capacitor begins to fail, you may notice the motor humming without spinning, struggling to reach full speed, drawing excess current, or shutting down on thermal overload — all signs of imminent motor failure if left unaddressed.
