Under normal circumstances, the rice cooker at home can be used for a few years, but it will inevitably cause such problems for a long time. The following is a small series of people who are going to take a look at the repair method of the rice cooker . .
Rice cooker failure and maintenance:
Rice cooker failure 1: Plug in the power plug, the power fuse will blow immediately
Causes and maintenance: 1. The rice cooker is filled with water or rice soup in the power socket, causing a short circuit. In this case, the inside of the socket can be dried and then used; 2. The rice cooker power socket or plug is short-circuited on the surface due to long-term use. In this case, the surface carbonized layer can be rubbed off with fine sandpaper and wiped clean with alcohol.
Electric rice cooker fault 2: can not keep warm after cooking
Cause and maintenance: The fault may be that the surface of the normally closed contact of the heat preservation switch is dirty or ablated, causing the contact resistance of the contact to be too large, causing the contact to close and the circuit to be unreasonable. The heating tube is not heated, and the rice cooker cannot be kept warm. At this point, the surface of the contact can be cleaned with fine sandpaper and plated with a layer of tin. If you still do not keep warm, you can replace the insulation switch.
Rice cooker failure three: boiled risotto
Cause and maintenance: This fault may be that the normally closed contact of the heat preservation switch is sintered together. Although the rice has been cooked, the temperature limiter also jumps off, but the heat preservation switch continues to energize the heat pipe, and the rice is smashed. At this point, the contacts can be separated by a small knife, and then the surface of the contacts is cleaned with fine sandpaper.
Rice cooker fault four: boiled raw rice
Cause and maintenance: This fault is generally caused by the weakening of the permanent magnetic ring in the temperature limiter. At this time, the temperature limiter of the rice cooker can be disassembled to check whether the magnetic ring is broken or the suction force. If the permanent magnetic ring breaks, the same type of temperature limiter must be replaced; if the suction force is reduced, adjust the temperature adjustment screw on the temperature limiter, adjust the 1/4 turn each time, and adjust the cooking time once.
Rice cooker fault five: can not cook rice
Causes and maintenance: 1, the source wire is broken. Check the power supply lead with the ohmmeter of the multimeter; 2. The current limiting resistor is blown. At this point, check the resistance with the ohms of the multimeter. If the resistor is blown, it must be replaced by the same type of current limiting resistor. It cannot be replaced by a wire directly. 3. The heating tube is blown. The rice cooker without current limiting resistor works for a long time and blows off the heating tube. At this time, check the heating pipe with the ohmmeter of the multimeter. If the circuit is broken, it must be replaced together with the heating plate.
Rice cooker fault six: heat preservation lamp bright cooking light is not bright
Causes and maintenance: 1, the heating plate is not heated, the power cable is bad; 2, the heating plate is not heated, generally the metal plate switch contacts are ignited and oxidized, as long as the sandpaper or small trowel is used to polish the contacts; Heat the plate to heat, check the rice cooking indicator and current limiting resistor.
Rice cooker failure seven: the rice appears brown, the magnetic steel lever can not fall, automatically reset
Causes and maintenance: 1. In the magnetic steel temperature limiter, the spring is tight, the elasticity is insufficient or the elasticity is lost, the spring performance is checked, and the magnetic steel temperature limiter is replaced; 2. The foreign matter is stuck to the dead spring, the foreign matter is removed, or the magnetic steel temperature limiter is replaced; 3. The magnetic steel lever is not flexible, skewed and hung, check the installation of the magnetic steel temperature limiter and the lever bracket, and adjust or replace the magnetic steel lever assembly.
Rice cooker fault eight: the circuit board can not automatically enter the risotto and insulation state
Causes and maintenance: 1, the main circuit board is damaged, replace the main circuit board; 2, the main thermostat is abnormal, replace the main thermostat.
The above is the introduction of the common faults and maintenance methods of the rice cooker. I hope that the above contents can help the big plan. If there is a problem with the rice cooker, please ask the professional maintenance personnel for repair. If there is a big problem, you can now Buying a new rice cooker will make it even safer.
