In normal use, the contact gaps of the switch changed due to arcing and pitting. If the starting switch fails to open when needed, the starting winding will be overheated and will eventually burn out.

Failure of Centrifugal Starting Switch:
When the centrifugal starting switch fails to close, it means that the switch fails to disconnect the starting winding from the power source as the motor reaches its operating speed. This can have detrimental effects on the motor's operation.
Effects of Failure:
- Starting Winding Overheating: The centrifugal starting switch is responsible for disconnecting the starting winding once the motor reaches its synchronous speed. If the switch fails to close, the starting winding will remain connected to the power source even after the motor has started running. This continuous connection can cause the starting winding to overheat and eventually burn out.
- Motor Running at Incorrect Speed: Without the centrifugal starting switch functioning properly, the motor may not reach its synchronous speed or may run at a speed slower than the synchronous speed. This can lead to inefficiency in motor operation and potential damage to the motor over time.
Conclusion:
In conclusion, when the centrifugal starting switch fails to close, it can result in the starting winding overheating and burning out, as well as the motor running at a speed slower than the synchronous speed. It is essential to address this issue promptly to prevent further damage to the motor and ensure its proper functioning.
