Common Issues with Commercial Extractor Fans

Fan not turning on

One common issue with commercial extractor fans is that they may fail to turn on when needed. This can be frustrating and can lead to poor ventilation in commercial spaces. There are several factors that could contribute to this problem, such as a faulty power supply, a malfunctioning switch, or worn-out wiring connections.
