What is the reason why the rice cooker indicator is always kept warm?

1. Reasons

1) The bottom of the pot is hot.

Poor surface contact (deformation or foreign matter).

2) If the core of the magnet is broken, it needs to be replaced.

3) The sensitivity is too high due to the deformation of the trip switch.

Data development. Second, the solution steps

1) If the rice cooker always jumps to the state of keeping warm when the rice is not cooked in the pot, first check whether there is dirt between the inner tank of the pot and the heating plate, and if so, it needs to be cleaned up.

2) If the rice cooker does not have any "observable" abnormalities, but it jumps to keep warm when the rice is not cooked, it is due to the "magnet" in the middle of the heating plate.

The reason for the "aging of the thermostat" is that in the use of the pot, the spring in the magnetic thermostat is often at high temperatures, and the magnet in the thermostat will suddenly disappear when the temperature of the pan is higher than 103 degrees (when the water in the pan is boiled dry), and this temperature is called the "Curie point."

temperature"; After the magnetism disappears, the spring in the thermostat resets the thermostat, and the circuit is turned to a state of insulation.

3) When working in a non-thermal heating state, if the thermostat is aged, it is easy to make the thermostat act before the temperature reaches 103 degrees (the thermostat also reaches more than 103 degrees and does not jump away and causes the bottom of the pot to burn), so to eliminate this fault phenomenon, the "magnetic steel thermostat assembly" should generally be replaced (the linkage rod of the thermostat assembly of the 1500 watt rice cooker is longer than the one of the 1000 watt rice cooker within 1000 watts in the general household, which is different). In this way, the problem can be solved effectively.

The computer board of the rice cooker is not reset, causing the boot to be in the state at the end of the last time;

The computer board is damaged, causing the function keys to malfunction;

The failure of the temperature sensor causes the whole machine to enter the state of insulation directly without heating.

This may be because the computer board of the rice cooker has been damaged, so it is always kept warm.

It may be because the rice is ready, so it stops working and is in a state of heat preservation to prevent the rice from getting cold.

Because after the rice is cooked, the indicator light will automatically jump to the keep warm state.

Because he only has two states, one is to keep warm, the other is to cook rice, and when he is not cooking, he is kept warm.

It may be that the switch is broken, or the rice cooker is broken and cannot be used.

The indicator light of the rice cooker is always in a state of insulation, which is broken and repaired.

I think it's that the stuff is too hot, and the temperature is higher than the original.

Your pot temperature sensor and heating tube are broken, get a new one

After the rice is cooked, it automatically jumps to keep warm.

Summary. Hello.

Causes and solutions.

First of all, test whether the voltage at both ends of the heating plate is normal, if it is not normal, you should go forward to find out if the rest of the components are broken, if it is normal, a component in the branch of the cooking lamp is damaged or has poor performance, and you can replace it; In the same way, for the insulation lamp branch, according to this idea to measure, maintenance can definitely find the bad components.

Hope it helps.

The rice cooker keeps warm indicator light is not on.

Hello cause and solution: first measure whether the voltage at both ends of the heating plate is normal, if it is not normal, you should go forward to find out if the rest of the components are broken, if it is normal, it is a component in the branch of the cooking lamp is damaged or the performance is poor, you can replace it; In the same way, for the insulation lamp branch, also according to the idea of noisy belt to measure and repair, you can definitely find the dust and bad components. Hope it helps.

Solution 2: 1: The e-sensor is broken. Crush a white tubular element in the rice cooker with a lead at the bright end and marked with 130° with pliers, and then connect the leads at both ends to power on.

This method can only be used on an emergency basis and can be replaced as soon as the same component is purchased in the future. 2. First of all, change the electrical appliances to check whether the socket has electricity, and if there is a ride, check whether there is a problem with the plug wire, and whether there is poor contact, etc., and then press the switch for 5 seconds to open the lid.

Summary. Hello dear: the indicator light of the rice cooker is normal, but the reasons for not heating are as follows

Reason 1: If the fuse is blown out, the fuse will be burned out, which will cause the rice cooker to display normally but not be heated. Reason 2:

The cooking switch is in poor contact, the function key of the rice cooker is damaged, and the main unit of the rice cooker cannot receive the signal sent by the button, so it is displayed normally but cannot be heated normally. Reason 3: There is a foreign body in the gallbladderIf there is a foreign body in the inner tank of the rice cooker, it will cause the inner tank to not contact with the heater, resulting in poor contact.

The control system of the rice cooker also does not receive the signal of normal operation, resulting in the rice cooker displaying normally but not heating. .

The rice cooker indicator shows that it is normal, but it just doesn't heat up, what's going on?

Hello dear: The indicator light of the rice cooker is normal, but the reason why it is not heated is that the state lead has the following Oh: Reason 1:

A blown fuse will cause the rice cooker to display normally but not to heat up. Reason 2: The cooking switch is in poor contact, the function key of the rice cooker is damaged, and the main unit of the rice cooker cannot receive the signal sent by the button, so it is displayed normally but cannot be heated normally.

Reason 3: There is a foreign body in the gallbladderIf there is a foreign body in the inner tank of the rice cooker, it will cause the inner tank to not contact with the heater, resulting in poor contact. The control system of the rice cooker also does not receive the signal that the rice cooker is running normally, resulting in the rice cooker showing normal but not being heated.

Reason 4: The metal sheet of the heat preservation key of the rice cooker is damaged due to continuous heating, which will also cause a short circuit and will not heat up. At this point, the metal sheet can be replaced.

Reason 5: If the inner pot of the rice cooker is deformed, the heating is uneven, and the temperature in some positions is too high, resulting in the fuse resistor burning out and will not heat up. As long as the inner tank is carefully trimmed and the fuse resistor is replaced, Bi Huai can continue to use it.

Dear, the biggest possible reason is that the fuse is damaged, I have encountered it myself, and the fuse functions normally after replacing it.

Summary. 1. Hello, this situation occurs only if two components are damaged at the same time, that is, the warmer and the temperature limiter. When the insulator is broken and the thermostat is working normally, the two sides of the insulated lamp will not glow if it is short-circuited without pressure.

When the thermostat is damaged, the heater works normally, and the two ends of the insulation lamp are short-circuited without voltage, and will not be indicated. Only when the thermostat and heater are damaged at the same time, the insulation lamp will have an indication, but the heating indicator will not be on. Moreover, the description in the question does not affect the use, which proves that the other functions are all right.

To sum up, there is only one reason for this failure: the temperature limiter has been damaged, and the poor contact of the switch contact of the insulator makes the switch equivalent to a resistor in series in the circuit, resulting in a small voltage at both ends of the switch, but the current can still supply power to the heating plate through the heat warmer. 2. At this time, the insulation lamp will naturally have an indication due to the voltage added on both sides, and the heating plate will work at the same time, and the heating indicator will also be on at the same time.

3. Maintenance method: Use the finest water sandpaper to polish the two contacts of the insulator, or replace the insulator directly.

1. Hello, this situation occurs only if two components are damaged at the same time, that is, the warmer and the temperature limiter. When the heat warmer is broken and the temperature limiter is working normally, the two sides of the heat preservation beam guess lamp will not glow if it is short-circuited without pressure. When the thermostat is damaged, the heater works normally, and the two ends of the insulation lamp are short-circuited without slag and high voltage, and will not be indicated.

Only when the thermostat and heater are damaged at the same time, the insulation lamp will have an indication, but the heating indicator will not be on. Moreover, the description in the question does not affect the use, which proves that the other functions are all right. To sum up, there is only one reason for this failure:

Hello, oh, dear The reasons why the rice cooker cooking light does not light up and the thermal insulation light are on are as follows: What is the reason why the rice cooker light is not lit 1First of all, a white tube-shaped element with a lead at the bright end and marked with 130° in the rice cooker is clamped with pliers, and then the leads at both ends are connected together to power on. This method can only be used on an emergency basis and can be replaced as soon as the same component is purchased in the future.

2.First of all, change the electrical appliances to check whether the socket has a slippage and suspicion of electricity, if there is, check whether there is a problem with the plug-in letter hand wire, and whether there is poor contact, etc., and then press the switch for 5 seconds, open the lid, there is heat in the pot is the problem of the power indicator, otherwise it is the internal temperature of the pot or temperature control and other local problems. It may be because there is a foreign object on the bottom of the pot or the heating plate, so that the inner pot of the rice cooker cannot fully contact the heating plate, if the temperature of the heating plate is too high, it will cause the fuse to burn out.

However, at the same time, it protects the heating plate of the rice cooker, carefully check the foreign matter at the bottom of the rice cooker or the heating plate, remove the foreign matter and clean the bottom of the pot or the heating plate, and be careful not to throw off the safety resistor.
