What should I do if I don't heat up after power on and the indicator light doesn't light up?
Faults are often caused by the power supply not being added to the electric heating tube circuit. When overhauling, you can first measure the resistance of L and N ends of the 3-core plug on the base power cord with a multimeter R× 10.
Under normal circumstances, the resistance is ∞ when the reset switch is not pressed, and the corresponding resistance is about 32 Ω when the button of 1500W electric kettle is pressed. If the resistance is still ∞ after pressing the button, it means that the heating pipe circuit is not working.
At this time, the resistance at both ends of the 3-core plug N and L of the kettle body can be measured again, and the normal value is the same as above. If the measurement results are normal, the fault is in the base part. Check the connection between the power cord and the base socket for open circuit or poor contact. The basic structure is simple and the fault can be found quickly.
If the measured resistance is still ∞, it means that the fault lies in the pot circuit, and the handle cover assembly should be disassembled for maintenance. The focus is on power (reset) switch and insulation switch. Use multimeter R× 1 to check whether the switch action and contact are good.
If it is found that its action is bad, check whether the bending angle of the temperature sensor uvula and the position of the switch connecting rod are normal, otherwise it should be corrected separately. If the switch works normally and the contact cannot be connected, it means that the switch reed or contact is damaged, and the switch box can be disassembled for cleaning and maintenance.
If the power switch is normal, the fault mostly occurs in the disconnector.
First, check whether the bimetallic reed presses the switch lever (white plastic lever). If it is pressed too tightly, bend it upward with tweezers until the distance between them is 0.5 ~1mm. If the distance between the bimetal and the contact rod of the switch is normal, disassemble the switch box and clean and maintain the contacts and reeds of the insulated switch.
It does not generate heat after power-on, and the indicator light is on. What's the matter?
The indicator light is on, indicating that the power supply has been added to the indicator circuit. The fault lies in the electric heating tube or its connecting part. The common electric heating tube is damaged and the contact is poor. You can tell by removing the electric heating tube and measuring its resistance.
The electric heating tube is damaged and can only be replaced generally. The poor contact is mainly due to the serious corrosion or deformation of the contact reed in the power plug assembly. The switch box can be disassembled for cleaning and maintenance, and it is best to replace it with a new one if it is seriously damaged.
How to solve the problem of uninterrupted power supply after water is boiled?
Mainly caused by the failure of the reset switch. The common reason is that the temperature sensor is seriously deformed or the action of the switch connecting rod is blocked.
For the former, the convex angle of the tongue of the temperature sensor can be bent again to push the switch connecting rod to work normally. For the latter, it is necessary to find out the blocked part or foreign body. Generally, as long as the foreign body is taken out, the corrected position can return to normal.
What is the solution of uninterrupted power supply during dry burning?
When the water in the pot is boiled dry or the pot is empty for a period of time, there is no automatic power off, which is mostly caused by the failure of the insulation switch. Check whether the bimetal is deformed or loose. If it is deformed, it can be recalibrated with needle-nosed pliers. The distance between the bimetal and the switch contact rod should be 0.5 ~1mm. If it is loose, tighten its fixing screws.
How to solve the slow heating speed?
Common reasons are low power supply voltage and poor contact of indoor power supply lines or plugs and sockets, which should be eliminated first. Then check whether the electric heating tube is seriously scaling and whether the contact between the base and the power plug seat of the kettle body is seriously bad.
If the electric heating tube is dirty, you can scrape it gently with a knife first and then polish it with fine sandpaper. If the contact between the base and the power socket of the kettle body is seriously bad, the socket contact piece, contact oxide layer and dirt can be removed first, and then the shape can be corrected to make the contact close and good.
Correct use and maintenance of electric thermos bottle
Electric thermos bottles are very popular with everyone because of their convenience and convenience, and are used by ordinary families. However, have you mastered the correct use? Is your maintenance method proper? After reading our article, I hope you can be inspired.
Key points of using electric thermos bottle
1. After you buy the electric kettle, you should read the instructions carefully to know its maximum power, so that you can configure the corresponding patch panel and put it in a place where children can't reach it easily to avoid burns.
2. Check the switch of the electric kettle before electrifying to ensure that the switch of the power supply is in the off position, so as to avoid the impact current from damaging the body and affecting the service life.
3. When adding water, be careful not to exceed the highest water level line to avoid damage.
4. When the electric kettle is running to boil water, special attention should be paid to avoid the overflow of boiling water, causing short circuit to the body, and it should be placed out of the reach of children to ensure safety.
It may take some time for the electric kettle to boil water, so you need patience. You can't open the lid of the kettle, so as not to burn your face or hands by steam, causing Shanghai.
6. When the electric kettle is boiling water, please unplug the power supply in time, or ensure that the switch of the electric kettle is in the off position to prevent the overheating of the chassis from causing danger.
7. The electric kettle will generate heat energy when it is working, and it is normal for the fuselage to heat up. Therefore, when grasping, you can only hold the handle or hold a wet towel in the other hand, and you must never touch it directly.
It should be noted that the function of the electric kettle is only to boil water, and it should never be used to cook other things. Moreover, if there is no water in the kettle, don't dry it to avoid danger.
The thermos should be flat. To avoid uneven heating. At the same time, because the general electric thermos bottle is made of plastic shell, it should not be placed near the stove, various combustible gases and other heat sources, otherwise it will bake the surface and affect the appearance. Heavy weight may make the thermos useless.
Bian Xiao introduced so much information, hoping to help everyone repair the Rongshida electric kettle as soon as possible. Royalstar electric kettle is one of the brand hot kettles used by the public now, which brings advanced technology and health protection to everyone. As an important tool for people's daily drinking water, the electric kettle boils at the temperature of 100 degrees, which deactivates the enzymes in the bacteria, and then the bacteria die, producing pure drinking water for everyone and ensuring everyone's health.
