OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PEB060090NB

This genuine OEM Carrier single run capacitor is the factory-specified replacement for the Carrier PY2PEB060090NB packaged unit. The run capacitor remains in the circuit continuously while the motor operates, providing the steady electrical charge needed to keep the fan motor or compressor running efficiently. When it fails, you'll typically notice a buzzing or humming sound from the unit, the motor struggling or failing to start, or the system short-cycling and blowing warm air instead of cooling.

Generic capacitors often run outside factory tolerance, accelerating motor wear and shortening equipment life.
