Only need to replace the hot plate, because the heating tube is forged inside the aluminum plate.
Reason and overhaul:
(1) Water or millet soup leaked from the power plug of the rice cooker, resulting in a short-circuit failure. This type of situation can be used again after drying the water in the power socket.
(2) The surface of the rice cooker power plug or power plug is short-circuited due to carbonization of the surface due to long-term use. In such conditions, the carbonized layer on the surface can be rubbed off with water sandpaper and cleaned with ethanol. Disadvantages: Can not cook rice and overhaul:
(1) The switching power supply line is short-circuited. Use the European female block of the digital multimeter to check the switching power supply line.
(2) The overheating protection device is fused. At this time, the resistor can be checked with the European female block of the digital multimeter. If the resistor is fused, it must be replaced with the same type of power resistor, and it cannot be replaced with a power line immediately.
(3) The heating tube is burned out. The rice cooker without overheating protection device has been working for a long time, and the heating tube is burned out. At this time, check the heating tube with the European female block of the digital multimeter. If it is short-circuited, it must be replaced together with the hot plate. Disadvantages: cooking with raw rice and overhaul: This disadvantage is generally caused by the weakening of the permanent magnetic core in the temperature limiter. The double-tube heating plate is processed. At this time, the temperature limiter of the detachable rice cooker checks whether the magnetic core is cracked and what is the adsorption force. Disadvantages: cooking rice sake and overhaul: This shortcoming may be that the normally closed points of the heat insulation power switch are calcined and stuck together. Although the meal has already been cooked, the temperature limiter has also jumped off, but the heat insulation power switch is still working again Plug in the heating tube and the rice will be simmered.
