OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PPA060090NA

This is the factory-specified OEM single run capacitor for the Carrier PY3PPA060090NA packaged unit. The run capacitor maintains a continuous phase-shifted current to keep the condenser fan motor or blower motor spinning efficiently after startup. When this capacitor fails, you will typically notice the motor humming but not turning, intermittent short-cycling, or the unit shutting down on thermal overload due to motor strain. Replacing it promptly prevents permanent motor winding damage.
