Hello, for this kind of issue I would recommend to check the following ceiling fan troubleshooting guide. It is the guide I usually recommend to people when their fan is not turning as it has a in-depth guide that takes you step by step, through checking each part of the fan until you determine the issue.

More than likely it would be a wiring or motor issue, check the guide and let us know if it was helpful or not.
