Why does the fan not spin at the first speed but only at the third speed?

[MacEvelyn]

It is caused by the decrease in the capacity of the fan starting capacitor. Replacing it with a capacitor of the same capacity will solve the problem. Fan capacitors are generally divided into two types: starting capacitors and running capacitors. The relevant introduction is as follows: 1. Starting capacitor and running capacitor: The starting capacitor assists the motor during startup and becomes inactive once the motor starts running; the running capacitor continues to assist the motor operation even after startup, meaning it remains active. The capacitor in an electric fan is usually a starting capacitor. 2. The function of the fan: A fan refers to a device used to generate wind for cooling on hot days. An electric fan is a device that uses electricity to generate airflow, with an internal configured blade that rotates when powered to create natural wind for cooling purposes.
