Leakage of Panasonic electric rice cooker

Disconnect both ends of the heating plate and measure with a shaker to see if the heating plate is leaking electricity. If so, replace the heating plate. You don't need to shake the insulation resistance of each component separately to identify the leaking component. Set the multimeter to its highest resistance, with one probe touching the heating plate of the rice cooker and the other probe placed on the lead of the tested component. Check if the hand is swinging. It is best to only use a pointer type multimeter, as the digital multimeter cannot display the resistance value when it exceeds the range, and the pointer can rotate slightly when it exceeds the range. When the leakage resistance is high, the multimeter may not be able to correctly locate the leakage location. Also, if the plug may be broken, replace it; Also, check if there are any black marks on the bottom of your rice cooker and clean it up. Pay attention to cleanliness and do not plug it in.

The switch is completely mechanical and has a normally open contact. When cooking, press this switch to turn on the power of the heating tube and turn on the heating indicator light to light up. The meal is ready, and the temperature limiter pops open, driving the lever switch to open the contact. Afterwards, the heating tube is only controlled by an insulated switch.
Current limiting resistor: The appearance is mostly gold or white, and the size is like a 3W resistor. It is pressed between the heating tube and the power supply to protect the heating tube. The commonly used current limiting resistor is 185C 5A or 10A (depending on the power of the rice cooker). The current limiting resistor is a key component for protecting the heating tube and can be replaced by wires!
