Resistance is very common in our household appliances, and almost every appliance has a resistor. Many household appliances are easily damaged, causing the circuit to malfunction and affecting the use of the appliance. The rice cooker is an electrical appliance that we must use every day. The resistance inside it is most vulnerable to damage. How to judge whether the resistance in the rice cooker is damaged? We summarize the following points as follows:

 
Second, check the stability of the rice cooker line;
When using rice cookers to contact electricity, many households like to insert switches. Long-term use of this method can easily lead to unstable socket contact, so that the power supply voltage will also change, so many of them tend to cause voltage instability, and the resistors inside damage, in this case we also need to perform resistance detection.
 
Third, the foreign matter at the bottom of the pot causes resistance damage

It is very important to clean the rice cooker daily. It is easy to produce foreign matter in the place where it is heated, so that the inner pot of the rice cooker cannot be in full contact with the heating plate. If the temperature of the heating plate is too high, the resistance will burn out. All the foreign materials of the rice cooker's bottom or the hot plate should be carefully inspected, the foreign matter should be removed and the bottom of the pan or the heating plate cleaned, and the resistance should be checked for damage in time.
 
The above three points are the most common cause of resistance damage in the reason that the rice cooker does not heat. If this problem occurs, the family should consider detecting the resistance. If you find that the resistor is burned and replaced in time, you can let the rice cooker work again, so as not to spend more money to buy new electrical products.
