Rice cooker not heating, help? The rice cooker is powered on but not heated

The reason why the rice cooker is on the light but cannot be heated: 1. The reason why the rice cooker is not heated may be that the fuse resistor is burned out, and the fuse resistance of the rice cooker may be burned out because there are foreign objects on the bottom of the pot or the heating plate, so that the inner pot of the rice cooker can not be fully in contact with the heating plate, if the temperature of the heating plate is too high, it will cause the fuse resistor to burn out, but at the same time, it protects the heating plate of the rice cooker, and carefully check the foreign body at the bottom of the rice cooker or the heating plate, remove the foreign body and clean the bottom of the pot or the heating plate, Be careful not to throw off the fuse resistor. The bimetal sheet used to keep the heat of the rice cooker is accidentally adhered to the contacts, which is easy to cause the fuse to be burned out due to continuous heating, so pay attention to replacing the bimetal sheet.

2. If you do not pay attention to the use of the rice cooker, resulting in the deformation of the inner pot or the deformation of the heating plate, it will also cause the temperature to be too high, which will cause the insurance to be burned, if this is the case, you should carefully trim the inner pot of the rice cooker to restore the original state, and the repaired inner pot can still be used, but the heating plate that has been deformed can not be used, and it should be replaced with a new one 3. The heating plate of the rice cooker is in an open circuit state, which will also make the rice cooker unable to heat, and it should be carefully checked and maintained.

The rice cooker is not heated, first check whether the voltage of the rice cooker is normal, secondly, check whether the temperature sensor of the rice cooker is open or whether the heating plate is open, check whether the rice cooker, computer board, and driver board are faulty?

1. It may be that the temperature control of the rice cooker is faulty: the ordinary rice cooker is mainly composed of a heating plate, a temperature limiter, a heat warmer, a fuse power connector, a thermal insulation indicator and resistance, a rice cooking indicator and a resistor. If the thermostat or warmer is damaged, the rice cooker will not work when it is powered on.

In particular, the contacts in the thermostat are consumables, and if you have the ability, you can open the bottom three screws of the rice cooker to see if its contacts are blackened or burned. If the capacity is insufficient and the replacement is difficult, it can be sent to the after-sales warranty or professional maintenance organization for repair.

2. It may be the fault of the heating plate: when the temperature is lower than 60, the heat warmer is connected to the power supply to make the heat plate work, when the temperature of the heat plate is 80, the internal thermal expansion and cold contraction of the heat warmer is disconnected, and the power supply to the heat plate is stopped by disconnecting the contact. If the heating plate is damaged, the process will not work properly.

If you have the ability, you can use a multimeter to measure whether the heating plate has a resistance value, if the resistance value is infinity, it means that the rice cooker is not working because the heating plate is damaged. If the capacity is insufficient, it can be sent to the after-sales warranty or professional repair organization for repair.

It may be that the plug is not plugged in properly or the power cord is broken, and it will not be heated if it is not powered on; It may be caused by foreign bodies on the inner tank, bad contact with the heating plate, and burning out the resistor; It may be that the metal sheet inside the heat preservation key of the rice cooker is burned out; It may be caused by damage to the rice cooker selector switch or internal wiring.

If your rice cooker light is on, it means that the heater in your rice cooker is broken, or there is a bad contact with the wiring inside, you can open it and take a look.

It may be that the temperature control of the rice cooker is faulty or damaged, and it is recommended to replace the thermostat (if it is difficult to replace, it can be sent to the after-sales warranty or professional repair organization for repair); It may also be that the heating plate is burned out, and it is recommended to send it to an after-sales warranty or professional maintenance organization for repair.

The rice cooker is not heated in this state, usually it is related to its quality, and some parts may fail due to a long period of use, so in order to make it more safe and stable to be applied, it must be professionally repaired.

The problem with your rice cooker is that a wire is broken, if you have some facilities for electric welding, you can weld it yourself, if you don't have these tools yourself, you can go to the repairer to help you fix it.

Bought in**? You can contact the store for after-sales repair.

Not bad, think you want to blow you, you want to turn into a few quarrels, fnnf, that can be sealed for a long time, and the bitter coffee enters the workshop.

1. The plug is not plugged in well or the power cord is damaged, resulting in the rice cooker cannot be powered on normally, and there may be no heating, the easiest repair method is to check the plug and power cord, and deal with it according to the situation.

2. There are foreign bodies in the inner tank, which leads to poor contact between the inner tank and the heater, and the rice cooker may not be heated. In addition, if the heater is not in sufficient contact with the inner tank, the safety resistor may burn out, and the easiest way to deal with it is to remove the foreign matter, wipe the bottom of the inner tank, and then press.

3. The metal sheet of the heat preservation key of the rice cooker is damaged, resulting in continuous heating, which will also cause a short circuit and not heating.

4. The inner tank of the rice cooker is deformed, and the heating is uneven, which causes the temperature of some positions to be too high, causing the fuse resistor to burn out, and there will be no heating.

5. The rice cooker has a selector switch, then, the cause of the failure may also be the damage of the switch, test it with a multimeter, and replace it if it is damaged.

6. The internal wire of the rice cooker is broken, find out the short circuit, and reconnect it so that it can be used normally. However, it should be noted that the technical requirements for wire maintenance are relatively high, and it is best to find professional maintenance personnel to deal with it.

1. It may be that the fuse resistor is burned out, and there are foreign objects on the bottom of the pot or the heating plate, so that the inner pot of the rice cooker can not be fully in contact with the heating plate, if the temperature of the heating plate is too high, it will cause the fuse resistor to burn out, and carefully check the foreign matter at the bottom of the rice cooker or the heating plate, remove the foreign body and clean the bottom of the pot or the heating plate, and be careful not to shake off the fuse resistor.

2. If you do not pay attention to the use of the rice cooker, resulting in the deformation of the inner pot or the deformation of the heating plate, it will also cause the temperature to be too high, which will cause the insurance to be burned.

3. If the heating plate of the rice cooker is in an open state, it will also make the rice cooker unable to heat, so it should be sent to the repair shop for inspection.

Did you press the start button?

1. The power supply is not energized, and the internal fuse is blown out;

2. The connecting wire at the power plug or socket is loose or corroded;

3. The power lead is broken, check the power lead, check the two wires with a multimeter, if the resistance value of the two wires or one of them is infinite, it means that the power lead is broken inside;

4. After connecting the power lead, before pressing the switch button, the indicator light does not light up and the pot is not hot, which means that there are debris or oxides between the dynamic and static contacts of the heat warmer;

5. If the heating wire in the electric heating pipe is broken, check the two leads of the electric heating pipe with a multimeter file, if it is not conducted, it means that the internal circuit of the electric heating pipe is broken;

6. Open the bottom cover and use the multimeter ohm file to measure the resistance value at both ends of the electric heating plate, if it is infinite, it means that the electric heating plate is broken.

If the rice cooker is not heated, see if the insulation indicator is on, if it is not lit, it proves that the rice cooker is not electric, if it is on, one is that the switch is not turned on (the contact is not connected), and the other is that there is a thermistor in the rice cooker (used to protect the rice cooker) with the change of temperature, the resistance value is changing, in general, it is mostly damaged, and there are 1 2 yuan on the market, you can buy it back and save some money.

Do you have a multimeter? If not, it's not easy. Borrow one to try.

If the multimeter pointer or number does not move, then the heating plate is burned out. If the pointer is swinging, the heating plate is good.

This changes the multimeter to AC voltage gear (V) Note that it is a red letter, and there is a letter below it, 250V gear. Don't use any other gear.

Also, pay special attention to safety. With the power on and the rice cooker pressing tablet down, test the two binding posts of the heating plate. If the multimeter pointer does not move or moves very little. Then the control circuit is faulty. Repairs are more cumbersome. It's better to ask a professional for help.

The reason why the rice cooker is not heating may be that the fuse resistor is burned out, and the fuse resistor of the rice cooker is burned out, which may be because there is a foreign object on the bottom of the pot or the heating plate.

If the temperature of the heating plate is too high, it will cause the fuse to burn out, but at the same time it protects the heating plate of the rice cooker.

Related Notes:

The main structure of an ordinary rice cooker is composed of a heating plate, a temperature limiter, a heat preservation switch, a lever switch, a current limiting resistor, an indicator light, a socket, etc.

The heating plate is the main heating element of the rice cooker. It is an aluminum alloy disc with an embedded electric heating element, and the inner pot is placed on it, and it can be seen when the inner pot is removed.

Temperature limiters are also called magnets. It is equipped with a permanent magnetic ring and a spring that can be pressed and positioned on the heating plate. When cooking, when pressing the rice cooking switch, the suction of the magnet drives the lever switch to keep the power contact on.

When cooking rice, the temperature of the bottom of the pot continues to rise, the suction of the permanent magnetic ring weakens with the increase of temperature, when the water in the inner pot is evaporated, the temperature of the bottom of the pot reaches 103 2, the suction of the magnetic ring is less than the elastic force of the spring on it, the temperature limiter is pushed down by the spring, driving the lever switch, cutting off the power supply.

Insulation switch. Also known as a thermostat. It consists of a spring plate, a pair of normally closed contacts, a pair of normally open contacts, and a bimetal sheet. When cooking rice, the temperature inside the pot rises, and the two metal sheets that make up the bimetal sheet have different thermal expansion rates, resulting in the bimetal sheet bending upward.

When the temperature reaches more than 80, under the impetus of the upwardly bent bimetal sheet, the spring plate drives the normally open and normally closed contacts to convert, thereby cutting off the power supply of the heating element and stopping the heating.

When the temperature in the pot drops below 80, the bimetal sheet gradually cools and recovers, and the normally open and normally closed contacts are switched again, and the heating element is connected to heat up. Repeatedly, the heat preservation effect is achieved.

That is, the contact switch is not in contact, and it cannot be short-circuited, and the short-circuit will burn the rice. In fact, it is not difficult to deal with the method: 1. Adjust the rod on the switch to, when the lever is pressed, the switch can be in good contact, and when the lever is released, the switch can be pressed to disconnect.

Simple judgment of whether the switch is in good contact: press the lever, the heating light is on, release the lever, the insulation light is on, repeat it several times, it is like this, which proves that the switch is repaired and can be used.

The rice cooker is powered on and the ID is normal but not heated, most of them are broken here, the master teaches you to check and repair, and it is good to replace it, it is very simple.

If the pot doesn't last long, you can use fine sand paper to sand the contacts inside up and down, use needle-nose pliers to gently move the electrocuted copper sheet to adjust the contact distance, not short-circuit, light to burn the fuse resistor, heavy to burn the heating plate!

If the contact switch is broken, change to the same model, and the temperature will run out of control on the short circuit.

In this case, it may be that the power supply is weak, and it is recommended that you try to change the socket.

Maybe the temperature control is broken, and you press down the round shrapnel inside with your hand after you turn on the power, and then press it to cook rice to see what it will look like?

Summary. The reasons may be: faulty temperature control, faulty heating plate, wrong plug plug or damaged power cord, foreign body in the inner tank, damaged metal plate of the insulating key of the rice cooker, damaged metal plate of the insulating key, deformation of the inner liner of the rice cooker, failure of the switch, broken wire inside the rice cooker, etc.

Hello, the original spine can be believed to seepage energy is: temperature control for some reason, heating plate failure, plug plug or power cord damage, foreign body in the inner tank, rice cooker insulating key metal plate damage, insulating key metal plate damage, rice cooker liner deformation, switch failure, rice cooker internal wire break, etc.

If the temperature control is faulty, the temperature limiter or the warmer is damaged, which will cause the rice cooker to not work if it is powered on. When the temperature of the heating plate is lower than 60 of Hail Huai, the heat warmer is connected to the power supply of the source to make the heating plate work, when the temperature of the heating plate reaches 80, the internal thermal expansion and contraction of the heat warmer is disconnected, and the power supply to the heating plate is stopped. If the heating plate is damaged, the process will not work properly.

If the plug is plugged in incorrectly or the power cord is damaged, it is easy to cause the rice cooker to not be able to enter the normal energized work of Sun Xing, and the rubber stool may affect the situation of not heating. There is a foreign body in the inner tank, and the rice cooker may not heat up due to poor contact with the inner tank and heater. In addition, if the heater and the inner tank are not in full contact, the safety resistance may burn out.

Damage to the insulating key metal plate of the rice cooker insulating key to the metal plate will cause it to always heat up, and it will also lead to a short circuit without heating.

Deformation of the inner liner of the rice cooker In the case of uneven heating, the temperature of some parts is too high, resulting in the fuse resistor burning out, and the fuse resistor will not be heated.
