OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PPB060090AA

This is the factory-specified OEM single run capacitor for the Carrier PY2PPB060090AA packaged unit. The run capacitor remains in the circuit continuously while the fan motor or compressor operates, stabilizing voltage and ensuring efficient, reliable motor performance. When this capacitor weakens or fails, common symptoms include a humming or buzzing noise with no motor start, the unit short-cycling, warm air output, or a visibly bulging capacitor case — all signs it's time for an immediate replacement.
