![]() Ensuring the rice cooker is not working Step 2. Place back the insulator of thermal fuse after.Do not replace thermal fuse with thin wires.Cut the wires in right angle, do not rock side to side the wire or bend. ![]() Do not use pliers as hammer it would likely results crack or break.Do not use screw driver with broken handle.Unplug the rice cooker from power source.Use to check the connectivity of circuitryįor your safety, these following must be observed.Use to check either the fuse is broken or not.It melts itself just to be sure the appliance will not be damaged by the uncontrolled heat. In short, it is a protection to every appliance. But, what will happen if this thermostat malfunctions and won’t work? The machine will heat up excessively and can cause fire.Ī thermal fuse is a safety device that cuts off the appliance from source when there is an excessive heat which is beyond the operation limit of the appliance. Thermostat will set off when temperature is getting hot, and will set on when temperature is below. It keeps the heating element at right temperature by turning on and off. Why should we use it?Īppliances that use heating element like coffee maker, dryers, heating cup and rice cooker have a temperature controller called thermostat. Fuses are not repairable, they are meant to be replace once broken. At the moment when the thermal fuse is blown or melted, there is no way to repair it. When its getting too hot, the material that holds the two metal plates together will melt down and separates the metal plates disallowing current to flow through between metals. At normal circumstances, the current flows through the combined metals. Is it made of two metal pieces which are attached together designed to melt down at a set temperature. While, a thermal fuse is more like an electrical fuse that melts as temperature surpass the limit and need to be replace. A thermal switch resets itself automatically when the temperature is beyond its limit. They are triggered by temperature but, they differ in action. A thermal fuse is different from a thermal switch. Thermal fuse is a device used to prevent appliances from overheating. Overview of this Tutorial What is a thermal fuse? Hope you will like it and find it educational. This is my personalized tutorial and these steps are based on my personal experience. You can check my last tutorial at: tutorial focuses only on a problem regarding with thermal fuse. My previous tutorial on rice cooker is more about determining the basic problems commonly encountered on rice cooker. This is my second tutorial on rice cooker.
