As our daily small household appliances, electric kettles have become sparse. Now these repair masters have become less and less, so many small problems we can solve ourselves are of course best. Otherwise, because the small problem will be broken, it is a pity to lose it.
The kettle is broken but the power switch is normal
If the power switch is normal, the fault occurs mostly in the heat preservation switch. First, see if the reed of the bimetal is pressed against the switch lever. If the pressure is too tight, use a pair of tweezers to bend it upward until the distance between the two is 0.5-1 mm. If the distance between the bimetal and the switch lever is normal, the switch box should be removed and the contacts and reeds of the heat switch should be cleaned.
No heating after power-on, but the indicator light is on
The indicator light is on, indicating that the power supply has been added to the indicator circuit. The fault is in the heating tube or its connection part. The common electric heating tube is damaged and the contact is poor. It can be judged by removing the electric heating tube and measuring its resistance. The electric heating tube is damaged and can only be replaced. Poor contact is mainly due to severe corrosion or deformation of the contact spring in the power plug assembly. The switch box can be disassembled for cleaning and repair, and the damage is most important.
Can't break the water after boiling
Mainly due to the failure of the reset switch. Common causes are severe deformation of the temperature sensor or hindrance of the switch link. For the former, the convex angle of the small tongue of the temperature sensing sheet can be re-bent, so that the action of the switch connecting rod is normal. For the latter, it is necessary to find a blocked part or a foreign object, and generally it is normal to remove the foreign matter and correct the position.
Common causes are low power supply voltage, poor contact of the indoor power supply line or the connector block, and should be eliminated first. Then check whether the electric heating pipe is seriously fouled, whether the contact between the base and the power socket of the kettle body is seriously bad. If the electric heating tube is fouled, it can be scraped with a knife and then polished with fine sandpaper. If the contact between the base and the power socket of the kettle body is seriously bad, first remove the contact piece of the plug seat and the oxide layer of the contact, dirt, and then correct the shape so that the contact between the two is tight.
