How to repair a broken smart rice cooker, how to repair a broken rice cooker

Smart rice cookers have brought us a lot of help in cooking, but when we use smart rice cookers, what if there is a malfunction that causes the rice cooker to break? So today, I will introduce to you the causes of some failures of smart rice cookers and the methods of maintenance, so that you can better refer to and understand.

Overhaul: 1. Water or rice soup enters the power socket of the rice cooker, resulting in a short circuit. In this case, you can scrub the inside of the socket and dry it before continuing to use it.

2. The surface of the power socket or plug of the rice cooker is carbonized, in this case, it is best to replace the socket or plug with a new one. If the carbonization is not serious, it can be cleaned up, and it can also be used temporarily, but it is best to replace it if there are conditions.

Overhaul: 1. The power conductor is broken. Check the power leads with the ohmic stop of the multimeter.

2. The current limiting resistor is fused. This is more common. At this point, the resistor can be checked with a multimeter ohmic stop.

If the resistor is fused, it must be replaced with the current limiting resistor of the same model, and it should not be sloppy. 3. The heating element in the heating plate is burned out. At this time, use the ohmic block of the multimeter to check the heating element, if the circuit is broken, you can only replace the heating plate of the same model with a new one.

Maintenance: This fault is usually caused by the weakening of the magnetic force of the permanent magnetic ring within the thermostat. When leading, it can be disassembled, and it is the temperature limiter of the rice cooker to check whether the magnetic ring is broken and how the suction power is. If it has been damaged, it can only be replaced with a new magnet.

Service: This fault may be caused by the normally closed contacts of the insulation switch being sintered and adhered together. Although the thermostat jumped off after the rice was cooked, the insulation switch continued to energize the heating pipe, and the rice burned out.

At this point, you can use a knife to separate the contacts and clean the surface of the contacts with fine sandpaper.

Overhaul: 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, causing the contact to be closed and the circuit to be blocked, and the heating element to not work. At this time, the contact surface can be cleaned with fine sandpaper and sanded smoothly.

If the ablation is severe, you can only replace it with a new insulation switch.

The above is the reason for some failures and maintenance methods of the smart rice cooker introduced to you, if you use the smart rice cooker in the future, you don't need to worry too much, you can refer to the above to overhaul the rice cooker, if necessary, please ask professional maintenance personnel to repair the fault for us.

If the smart rice cooker at home is broken, you don't need to go to the repair shop, and you can repair it at home at a low cost.

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

Causes and overhauls:

1) It may be that the rice cooker has a short circuit caused by water entering the inner tank when cooking rice, then we can use a hair dryer to dry the water inside, and then we can continue to use it;

2) It is also possible that the plug of the rice cooker is short-circuited, because the plug of the rice cooker is used for a long time and there is a possibility of a short circuit, then we can use sandpaper to grind off the oxide on the surface of the plug, and then wipe it clean with alcohol.

2. Do not keep warm after cooking

Causes and overhauls:

caused by the inability to keep warm. The reason may be that there are stains at the insulation switch, which will increase the resistance of the switch, and then the electric shock = the point will be closed, which will cause the heating tube not to heat up, so that the rice cooker can not keep warm, in this case we can use sandpaper to clean up the stains on the surface of the contact, and then plate a layer of tin on it, if it still doesn't work, then we have to replace a new insulation switch.

3. You can't cook rice

Causes and overhauls:

1) It may be that the power lead is broken, at this time we can use a multimeter to check the power lead;

2) If the current limiting resistor is burned out, then we first use a multimeter to check the resistor, if it is really broken, we need to buy a resistor of the same model to replace it;

3) It is also possible that the heating element is burned, if it is determined that the heating tube is broken after checking with a multimeter, then it needs to be replaced together with the heating plate.

4. The insulation lamp is on, and the cooking lamp is not on

Causes and overhauls:

1) It may be that the power cord is in poor contact, check the plug;

2) It is possible that the heating plate is not heated, in this case, the switch contact is oxidized, and only sandpaper needs to be used for a certain amount of polishing;

3) You can check the current limiting resistor and the rice cooker indicator.

5. The rice is browned, and the magnetic steel lever cannot fall and will automatically reset

Causes and overhauls:

1) It may be that the spring in the insulator is loose, or the spring has lost its elasticity, we should first check the insulator, and if necessary, we need to replace the insulator;

2) It is also possible that there is a foreign object that stuck, we can take out the foreign body, if it really can't be replaced, we can only replace the warmer;

Summary: Rice cookers play a very important role in our daily life, can help us cook, and can also make a few dishes at the right time, which is a kind of kitchen appliances that are used more frequently, so it is necessary for us to have an understanding of rice cooker maintenance knowledge, so as to make it more convenient for us to use in the future.

Smart model Chongneng rice cooker fault maintenance needs to be dealt with according to the specific fault situation, the following are some common faults and how to deal with them:

1.Power failure: Check whether the power plug is plugged in tightly, whether the power cord is damaged, and whether the power switch is normal.

2.Heating fault: Check whether the heating tube is damaged, whether the temperature controller is normal, and whether the heating switch is normal.

3.Control panel fault: Check whether the control panel has damaged or loose cables and whether the control panel needs to be replaced.

4.Liner failure: Check whether the liner is damaged or worn, and whether it is necessary to replace the liner of the coder.

5.Other faults: such as display failure, button failure, etc., need to be dealt with according to the specific situation.

When carrying out repairs, you need to pay attention to safety, and you disconnect the power supply and wait for the rice cooker to cool down before operating. If you are unsure how to deal with the fault, it is advisable to seek the help of a professional repairer.
