The heating plate of the rice cooker is measured as O by the multimeter with ohm file, indicating that the heating plate of the rice cooker is short-circuiting and broken. If the resistance value of the heating disc measured by the multimeter ohm file is about dozens of ohm, it indicates that the heating disc is not burned off and is good. When we repair the circuit or household appliances, we often use the ohm file of the multimeter to determine whether the circuit is on or off or whether the electrical components are good or bad. The general resistance value is small, indicating that the circuit is good, indicating that the short circuit is 0, and that the break is very large, which is bad.
To this question, my answer is: bad. If the ohm file of the multimeter is used to measure the heating plate of the rice cooker, and the reading of the multimeter is zero, it proves that the heating plate is bad, that is to say, the heating wire of the heating plate is broken.
Under normal circumstances, use the ohm file of the multimeter to measure the heating disk, and the dial of the multimeter is to one hundred. That's my answer.
