Make sure you perform all component checks with the dryer UNPLUGGED. Dangerous voltages are still present inside a dryer even with the unit turned off.
Pay particular attention to the paragraph that discusses proper dryer ventilation. Most dryer heat related problems are attributed to poor ventilation that leads to dryer overheating to the point of failure. If you can't remember the last time you had your ventilation checked or cleaned, I would recommend you do so before replacing any failed components. Failure to do so may result in undesired drying results and premature failure of any components you have replaced.
The most common cause of dryer heat failure is a blown thermal cut-out (TCO). This component acts as a fuse and will blow when an overheat condition occurs. If it is determined that the TCO is bad, it is strongly recommended that you replace the hi-limit thermostat at the same time. Failure to do so may result in premature failure of replaced components. In many cases, the manufacturer sells these parts as a set (more cost effective to purchase this way, too). Both these components are located on the heater box adjacent to the heating element.
To access, remove the lower panel under the dryer door. This is accomplished by inserting a putty knife along the seam at the top of the panel about two inches in from each side. There is a retaining clip that needs to be depressed to release the panel. With the panel removed, the heating circuits are located on the right hand side under the drum. You can view drawings of your dryer at searspartsdirect.com by entering your model number. Use model number "110.66912690" for your search criteria. The heating circuits are listed under the "Bulkhead" heading. The heating element is listed as item number 14. The thermal cut-out is listed as item 47 and the hi-limit thermostat is item 48. NOTE: You can find the TCO and hi-limit thermostat sold as a set at appliancepartspros.com as part number AP3094224 (Your Kenmore dryer is manufactured by Whirlpool). This could save you some $ if one of these components is your problem.
If you have questions along the way, or require additional assistance, please let me know. I hope this helps you.
