If the dryer runs, but does not heat, you need to check the Thermal Cut-out and Hi-limit thermostat. The following link explains:

The TCO and Hi-Limit Thermostat are mounted on the heater box near the heating element. Read through the info I provided and double check the continuity of these components. If either the TCO, or Hi-Limit thermostat are bad, replace them BOTH at the same time. Failure to do so may result in premature failure of any replaced components. They are commonly sold as a set.
NOTE: The Thermal Fuse and Internal Bias Thermostat are located on the air blower housing. If the Thermal Fuse were bad, the dryer would not run at all. The Internal Bias thermostat may still cause heating problems, but is less likely. Replace it if you like, but I think you may have a TCO that has failed.
If there has been a failure of the heating circuits, I would recommend you do a thorough cleaning of the dryer exhaust ventilation ducting to ensure you have no clogs. Poor air flow is the number one cause of dryer failures.
If you have questions, please let me know. I hope this helps you.
