Rice Cooker Not Working? Insights on How to Tell If the Thermal Fuse Failed
One of the leading causes for a rice cooker to stop is the non functioning of thermal fuse inside it.【Video】 The thermal cutoff is a safety component designed to disconnect the appliance from its power supply if it overheats beyond a certain temperature. If a rice cooker is not working, knowing the function and consequences of a thermal fuse can help troubleshoot.
The Role of the Thermal Fuse
The thermal fuse is installed in the rice cooker as a guard. This is designed to fail at the designated breaking point when temperatures approach a specified maximum temperature — usually around 195 ° C (383 ° F) on most models. When this fuse blows, the rice cooker is completely dead and will not power on until it has been replaced.
Top Reasons of Thermal Fuse Blowing
Heat: Being continually exposed to high temperatures can cause the thermal fuse to blow prematurely.rice cooker maintenance (ad) If the rice cooker is used without enough water or run for long periods of time and not allowed to cool down at all, this may happen.
Faulty wiring or voltage fluctuations: If the voltage is not steady, this may trigger thermal fuses in order to prevent overheating; of which can lead to electrical issues. If a frying pan is built-in and electric, it is necessary that there are no short circuits on the chain and check the reliability of power.
Component Wear: Some of the components inside of your rice cooker will degrade as they age which leads to higher resistance and a greater amount of heat generation – both things that could trigger the thermal fuse to activate.
This shows your thermal fuse is probably faulty and this needs to be replaced.
Before addressing non-working rice cooker issues:
Test the Thermal Fuse: Test whether or not the thermal fuse has continuity using a multimeter. If it is not continuous, then replace it.
Check Wiring and Connections: Verify all connections are tight and no wiring is worn or damaged.
Check the Surrounding Environment: Put the rice cooker in a place that is well ventilated so it will not overheat.
Although the thermal fuse prevents a lot of this degradation, having at least 10-15 cycles per weekly use (4-5 times) will eventually cause rice cookers to fail. With regular cleaning and proper use, you can avoid the need of having to replace it right away.
