The answer to 'flickering ceiling fan' is that a flickering ceiling fan is often caused by a loose connection or a faulty motor. The most common symptoms are an intermittent flickering or dimming of the fan lights and uneven or erratic fan blade rotation. To solve the issue, you'll first want to check the wiring connections at the ceiling and fan motor to ensure they are secure. If that doesn't fix it, the motor may need to be replaced by a professional electrician.
Flickering ceiling fans can be a DIY fix if the issue is a loose connection, but a faulty motor will likely require a professional repair. Attempting to repair a ceiling fan motor yourself can be dangerous, so it's best to call in an expert electrician if the basic troubleshooting doesn't resolve the problem.
