Dryer shuts off after about 5 minutes. Replaced both items in the thermal cut-off kit. Still malfunctioning. Any suggestions?

Unplug the dryer, and remove the back cover. Using a multimeter, test each of the electrical components one at a time, removing the wires before testing. I suggest using an analog multimeter (the one with the needle) - they are very simple to use and understand. If the multimeter needle moves, the part is likely good. If the needle doesn’t move, the part is likely bad. Replace the bad part.
