Normally Heating devices are protected with what we called “Thermal Fuse” which are connected in Series to the Main Line, If you can locate it it looks like a small fuse, crimped in a wire sometimes and comes in a different color like yellow, white or black. sometimes it is covered by a shrinkable tube if you know it. If you can use a Multimeter you can test the Leads of the Heating Element from end to end there should be a low resistance reading from your meter should appear, if it not reads at all then your heating filament is open. Its a sealed type. please think always Safety do not work on it with Power connected , be sure Unplug the Power and ask for a qualified serviceman if your not sure on doing it. Have a nice day.
