Each capacitor stores and releases the electrical charge required to start and sustain dedicated motor windings. When either capacitor degrades or fails, you'll typically experience hard-starting motors, audible humming with no shaft rotation, intermittent tripping on thermal overload, or a system that short-cycles within minutes of startup. Replacing both at the same time is best practice — if one has failed, the other is likely near the end of its service life.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e P291-0403 — 4 MFD (microfarad) | 370V | Oval case | Single element | ±5% tolerance.
