The run capacitor maintains a continuous phase-shifted current to keep the condenser fan motor spinning at full efficiency after startup. When this capacitor degrades or fails, you'll typically notice the fan motor humming without spinning, the system overheating and tripping on high-pressure lockout, or the unit short-cycling. Replacing it promptly protects your compressor from the heat damage caused by restricted airflow.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | Cross-references: HC91CA007, GE 27L566, Genteq C307L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to Carrier's exact tolerance specifications.

Verify the MFD rating and voltage on your unit's data plate before ordering — voltage rating must be equal to or higher than the original. Note: Carrier has superseded P291-0753 with P291-0754 (440V); both 370V and 440V variants are compatible, as a higher voltage rating is a safe upgrade.
