Once the motor reaches operating speed, the start circuit removes the capacitor from the circuit. Because start capacitors are selected by electrical specification, BC-124 should only be used when the motor manufacturer, service data, or original capacitor calls for the same appropriate capacitance and voltage class.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing an existing BC-124 start capacitor\u003c\/li\u003e\n\u003cli\u003ePool or spa pump motor service where 124-149 MFD is specified\u003c\/li\u003e\n\u003cli\u003eRepairing a motor that has been correctly diagnosed with a failed start capacitor\u003c\/li\u003e\n\u003cli\u003eMatching an original start capacitor by electrical rating and physical fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy This Part Matters\u003c\/h2\u003e\u003cp\u003eA failed start capacitor can prevent a compatible motor from developing the starting torque it needs.
