If the model number is correct, this dryer has a thermal cut-out in the heating circuit along with a hi-limit thermostat. These components act as a fuse and will blow in an overheat condition to protect the heating element. Both components should read 0 ohms if good. If either component is defective, BOTH should be replaced at the same time. Failure to do so will result in premature failure of the components you replace.
You can replacement parts at any of the following websites:
searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com
The first three sites I have listed, also have helpful exploded view parts illustrations to assist you with locating and properly identifying any parts you may need.
The part numbers for the model you have listed are as follows:
Thermal Cut-Out - 40113801
Hi-Limit Thermostat - 62641
These components generally blow for a REASON. If the heating circuits are getting too hot, you may want to check the dryer interior cabinet and/or the entire run of the exhaust ducting from where it exits your dryer to the point where it leaves your home to ensure you have no kinks or clogs. The following link explains many of the common problems that can cause poor drying efficiency and longer dry times:

This is the NUMBER ONE cause of poor drying efficiency. A dryer in a clogged state or having improper air flow will not dry efficiently and will cause the heating circuits to overheat. Eventually, this can lead to component failures and is the source of many fire hazards.
If you have any questions, or if your model number is different, please post back with a correct model number and let me know. I hope you find this information helpful.
