Before assuming you have a bad heating element, read through the following link:

Most dryer heat related problems are attributed to poor ventilation which, in turn, causes the dryer to overheat to the point of failure. More commonly the Thermal Cut-Out (TCO) fails. The component acts as a fuse and must be replaced if bad. In addition, if the
TCO is determined to be defective, it is recommended that you
replace the Hi-Limit Thermostat at the same time. Both these components work in conjunction with the heating element and are
mounted on the heater box. The
TCO is located on the end opposite the heating element terminals. The Hi-Limit Thermostat is located adjacent to the heating element leads. These two components are
often sold as a kit. If you fail to replace both of them you can experience premature failure of the component you do replace.
Pay pa
rticular attention to the section that discusses
proper dryer ventilation. If you haven't checked or cleaned the exhaust ducting any time recently, now might be a good time to do so . A dryer left in a clogged or poorly ventilated condition will cause repeated failures in the heating circuit. Not to mention this creates a fire hazard.
If you read through the link and determine that you have a bad heating element, follow these steps to remove:
1. Unplug the dryer and remove the lower panel under the door.
2. Remove the lint screen from the dryer door.
3. Remove the blower fan housing vent cover.
4. Disconnect and label the component wiring on the heater box.
5. Loosen the mounting screw on the heater box front support.
6. The
entire heater box, with element inside, should slide out of the dryer.
7. There should be a couple of mounting screws on the component side of the heater box that you need to remove and the entire element slides out.
If you still have questions, please let me know. I hope this helps you.
