Fan start capacitor connection detection method

Household electric fans use single-phase ac motors, so they need a live wire and a neutral wire to work normally. However, in order to protect the motor, an additional electric fan starting capacitor needs to be installed, which can avoid the excessive current burns the windings.When installing this capacitor, it is necessary to detect the motor first. In addition, there are three wire ends on the motor. Set the multimeter to electric barrier and measure the resistance between the wire ends respectively. The two wire ends with large resistance are where the capacitor is installed.

Fan start capacitor connection method

The correct connection method of the electric fan starting capacitor,electric fans generally use non-polar capacitors, so there is no difference between positive and reverse connections, and standardized accessories do not need to be welded, just tighten them with screws in the original way.However, pay attention to the specifications when purchasing a new capacitor. Choose the same model. Too large or too small may cause new problems, especially if the capacitor is too small, it will not have the proper starting and protection functions. When it is too large, it may cause the electric fan to be scrapped.

Precautions for connecting the fan start capacitor

The connection method of the electric fan starting capacitor is very simple, so if the accessories can be bought, the user can complete the replacement by himself. However, those who have not been trained need to pay attention to safety during maintenance. First, the power must be cut off before operation, and it must not be operated with power on.Another thing is that the neutral wire and the live wire should not be reversed. For electric fans, the neutral wire and live wire can also work normally, but the electric fan will still be charged after it is turned off, which will increase the risk of electric shock and leakage.
