When you turn on your electric griddle, you choose a power level from 1 to 5.
The role of the thermostat is to maintain the griddle at the right temperature.
For example, if you have chosen power 4, the griddle will heat up to the corresponding temperature. At this point, the thermostat turns off the heating element and turns it back on again when the temperature starts to drop and so on to maintain the required temperature.
