Locate the name of the manufacturer, the model number, etc. Then google to see if you can order a new heat element. There are likely youtube tutorials out there to assist you as well if you are wanting to do it yourself rather than calling in a repair person.
Good chance your problem is with the heating element. Get the model number and order a new one. They are super easy to instal too. Just unplug the dryer, disconnect the old one, install the new one, and you’re done. I included a picture of one.
