Perform regular maintenance
Sometimes dryer repair parts aren't required to fix your dryer. One common fix is to simply clean debris and lint out of the exterior damper and vent tube. This type of buildup can not only cause improperly dried clothing, it can also cause fires with the potential to damage your clothing, dryer and home.
Check the operating thermostat
The next step in dryer troubleshooting is checking the operating thermostat, also called the cycling thermostat. This component senses air temperature inside the dryer drum and controls the heating element or burn in electric or gas dryers respectively, powering the heat source on and off at around 150 degrees Fahrenheit on the normal setting. A defective operating thermostat can cause no heat or overheating, and if it fails, you should replace it immediately.
Inspect the heating element
The heating element dries garments in your dryer by generating heat. If your dryer isn't heating, inspect the heating element for visible damage and replace if you find any. Check the power supply, and if the heating element is getting 240 volts of power and still not heating properly, replace it even if it doesn't look damaged.
