Introduction: The electric tea stove, also known as the electric tea stove and the electric boiling water stove, refers to the electric boiling water stove specially used for producing boiled water for making tea and drinking. Because the electric tea stove has no noise and waste gas, it is very environmentally friendly and easy to use. Now it has become the first choice for drinking equipment in hospitals, schools, factories, hotels, hotels and other units.
(1) What should I do if the electric tea stove doesn't heat up after being electrified and the indicator light doesn't light up?
failures are often caused by the power supply not being connected to the electric heating tube circuit. Can you use a multimeter r first when overhauling? 11, measure the resistance at both ends of the 3-core plug L and N on the base power cord.
(1) when it is normal, the resistance is? When the button is pressed, the corresponding resistance of the 1511W electric kettle is 32? About. If the resistance is still 1 after pressing the button? , indicating that the heating pipe circuit is blocked.
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 measured results are normal, it indicates that the fault is in the base part. Check whether the connection between the power cord and the base socket is open circuit or poor contact. The base structure is simple, and the fault can be found quickly.
(2) if the measured resistance is still? , indicating that the fault is in the pot circuit, and the handle cover assembly should be disassembled for maintenance. Focus on the power (reset) switch and insulation switch. Can you use a multimeter r? Check whether the switch action and contact make-and-break conditions are in good condition at gear 1.
(3) 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 operates normally and its contacts cannot be connected, it means that the switch reed or contacts are damaged, and the switch box can be disassembled for cleaning and maintenance.
(2) If the power switch is normal, the fault mostly occurs in the thermal insulation switch
First, check whether the reed of the bimetallic strip is pressing the switch contact rod (white plastic rod). If it is pressed too tightly, use tweezers to bend it upward until the distance between them is 1.5 ~ 1 mm. If the distance between the bimetal and the switch contact rod is normal, the switch box should be disassembled, and the contacts and reeds of the insulation switch should be cleaned and maintained.
(3) After the power is turned on, it is not heated, but the indicator light is on. What's wrong?
the indicator light is on, indicating that the power supply has been added to the indicator light circuit. The fault lies in the electric heating tube or its connection part, and the electric heating tube is commonly damaged and poorly contacted. You can judge 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 detachable switch box should be cleaned and repaired, and it is best to replace it with a new one if it is seriously damaged.
(4) how to solve the problem that the water is not electrified after boiling?
it is mainly caused by the failure of the reset switch. The common reasons are serious deformation of the temperature sensor or blocked action of the switch connecting rod. For the former, the convex angle of the tongue of the temperature sensor can be bent again to make it push the switch connecting rod to work normally. For the latter, it is necessary to find out the blocked part or foreign body, and generally it can return to normal as long as the foreign body is removed and the position is corrected.
(5) what is the solution of uninterrupted power supply during dry burning?
when the water in the pot is boiled dry or the empty pot is not automatically powered off after a period of time, it 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 re-calibrated with needle-nosed pliers, and the distance between the bimetal and the switch contact rod should be 1.5 ~ 1 mm. If it is loose, just tighten its fixing screw.
(6) how to solve the slow heating speed?
Common causes are low power supply voltage and poor contact of indoor power supply line or plug socket, which should be eliminated first. Then check whether the electric heating tube is seriously fouled, 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, it can be scraped lightly with a knife first, and then polished with fine sandpaper. If the contact between the base and the power plug socket of the kettle body is seriously bad, the contact piece of the plug socket and the contact oxide layer and dirt can be removed first, and then the shape can be corrected to make the contact close and good.
