We all know that rice cookers can be used to cook rice, porridge and soup. In fact, rice cookers are not only these functions, but also many other very practical functions. In fact, rice cookers can also be used for cooking, especially for many people who rent a house alone. Electric cookers can be used not only for steaming and boiling, but also for stewing, stewing and other processing methods, so people can cook various dishes through electric cookers. Today, Rabbit wants to introduce the common faults and maintenance methods of triangle rice cookers, so as to avoid these problems in the future and know how to deal with them.

Common faults and maintenance methods of triangle brand rice cookers;

Fault 1: Plug in the power plug and the power fuse will blow immediately.

Cause and maintenance: 1, short circuit caused by water or rice soup in the power socket of rice cooker. In this case, you can dry the water in the socket and continue to use it; 2. Due to long-term use, the surface of the power socket or plug of the rice cooker is carbonized and short-circuited. In this case, the carbonized layer on its surface can be ground off with fine sandpaper and cleaned with alcohol.

Fault 2: You can't keep warm after cooking.

Reason and maintenance: This fault may be that the normally closed contact surface of the insulation switch is dirty or ablated, which makes the contact resistance of the contact too large, resulting in the contact being closed and the circuit being blocked, the heating tube not heating, and the rice cooker not keeping warm. At this time, the contact surface can be cleaned with fine sandpaper and plated with a layer of tin. If the insulation is still not maintained, the insulation switch can be replaced.

Fault 3: cooking rice

Reason and maintenance: This fault may be that the normally closed contacts of the insulation switch are sintered and stuck together. Although the rice has been cooked and the temperature limiter has jumped off, the insulation switch continues to energize the heating tube, and the rice is stale. At this time, the contact can be separated with a knife, and then the contact surface can be cleaned with fine sandpaper.

Fault 4: Cooking raw rice

Cause and maintenance: This fault is generally caused by the weakening of the magnetic force 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 and how attractive it is. If the permanent magnetic ring is broken, the temperature limiter of the same model must be replaced; If the suction force decreases, adjust the temperature adjusting screw on the temperature limiter, and adjust 1/4 turns each time, and try to cook rice once.

Fault 5: Can't cook.

Cause and maintenance: 1, open circuit of source conductor. Check the power conductor with the ohmmeter; 2. The current limiting resistor is blown. At this time, the resistance can be checked by the ohmmeter. If the resistor is blown, it must be replaced by the current limiting resistor of the same model, and it cannot be directly replaced by a wire; 3. The heating tube is burnt out. A rice cooker without limited current resistance works for a long time and burns out the heating tube. At this time, check the heating tube with the ohmmeter. If the circuit is broken, it must be replaced together with the heating plate.

Fault 6: The heat preservation lamp is on and the cooking lamp is not on.

Causes and maintenance: 1, the heating plate is not heated, and the power cord is not good; 2, the heating plate is not heated, generally the contact of the metal switch is oxidized by ignition, as long as the contact is polished with sandpaper or a small file; 3, heating plate heating, check the cooking indicator and current limiting resistance.

Fault 7: The rice is browned, and the magnetic steel lever can't fall, so it will automatically reset.

Causes and maintenance: 1, the compression spring in the magnetic steel temperature limiter is not elastic enough or loses its elasticity, check the spring performance and replace the magnetic steel temperature limiter; 2, foreign body stuck spring, eliminate foreign body or replace the magnetic steel temperature limiter; 3. The magnetic steel lever is inflexible, skewed and hung. Check the installation of the magnetic steel temperature limiter and lever bracket, and adjust or replace the magnetic steel lever assembly.

Fault 8: The circuit board cannot automatically enter the stew and heat preservation state.

Cause and maintenance: 1, the main circuit board is damaged, so replace it; 2. The main thermostat is abnormal. Replace the main thermostat.

The above are the common faults and maintenance methods of triangle rice cookers briefly introduced by Rabbit. I hope the above contents will be helpful for everyone to use rice cookers. Then if our rice cooker encounters the above problems, if we can repair it, we might as well try to repair it. If the maintenance is really bad, we'd better ask professional maintenance personnel to carry out the maintenance. Once there is a big problem, you can also buy a new rice cooker now, which will be safer.
