The run capacitor maintains a continuous phase-shifted current to the blower motor, keeping it spinning at rated torque and efficiency throughout every heating cycle. When this capacitor degrades or fails, you'll notice symptoms such as the blower motor humming without starting, sluggish or slow motor spin-up, overheating of the motor winding, or the furnace shutting down on a high-limit lockout due to insufficient airflow.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-rated MFD and voltage per Carrier specification for PG8MAA036045ACJA | Round or oval case (factory form-fit) | ±5% tolerance as required by OEM standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part.
