Thermo-teapot, or thermo pot is gaining immense popularity. However, its cost is high enough, therefore, to save money, some problems can be fixed independently. It often happens that a thermal sweat heats water, but does not boil it.
Causes of thermal sweat malfunction.
Before you start searching for the causes of a breakdown in a thermo kettle, you need to know what this object is. Thermopot is an electric kettle that includes the function of a thermos, consisting of two buildings. External, as a rule, is made of plastic, and internal - of metal. In the inner case there is a flask for water. The kettle closes with a lid, on which the entire control panel is located.
To fix any breakdown of the thermal sweat, the first thing to do is check the settings are correct. In the settings menu, you need to set exactly the temperature of water heating that is necessary. If everything is in order with the tinctures of heating, then the causes of damage can be:
- a thermal switch located on the bottom of the kettle;
- thermal fuse located on the wall of the thermal sweat;
- insufficient contact of any part connectors;
- malfunction of the electronic board;
- the indicator panel stopped turning off. There are cases when, on the contrary, the indicator panel turns on, and the thermal sweat does not start. If this is the cause of the breakdown, then it is worth checking all its components, wiring and thermal fuse.
- The kettle has stopped turning on. To eliminate this malfunction, it is necessary to check the correct operation of the electrical circuit and temperature switches.
In order to more accurately identify the cause of the breakdown of the gadget, you have to disassemble it.
How to disassemble the thermal sweat
- The first step is to remove the top cover, as it will interfere. The next thing to do is to turn the device upside down and use a flat and sharp something to remove the snap ring, for example, with a screwdriver or knife. To do this, it’s worth using some physical force.
- Several screws will appear under the corkscrew ring, they can easily be twisted with a curly screwdriver.
- The next step is to remove the bottom of the kettle with a knife or a flat screwdriver, requiring little effort, because the bottom is fixed with latches.
After that, all the electronic filling in front of the eyes. Now you need to check all the terminals for a tight connection.
Important! In order to properly disassemble the thermal sweat, you must have at least a little knowledge of electrics!
There are minor breakages in the kettle. In such cases, you can do it yourself.
Reasons Why Thermal Sweat Does Not Boil Water
Thermal breaker failure
Thermoswitches are located on the walls or bottom of the thermal sweat. This part is attached to the main body with bolts, from which the contact wiring departs. In order to maintain heat transfer inside the vessel, the attachment points of the thermal switches are coated with a special white compound. In order to remove it, you just need to disconnect the contact of the thermal switch and pull it out. In the quiet position, the switch will turn on. You can check its serviceability using a special tester (its readings should be equal to 0). It is necessary to fasten two wires to the thermal switch and lower it in boiling water.At this time, its resistance should increase, and the tester should show an infinite number - such readings indicate the serviceability of the part. If the tester readings do not budge, then you need to replace the thermal switch with a similar one.
Important! Before buying a thermal switch, consult an electrical engineer or retailer at the store.
If thermopot constantly boils waterthen you should pay attention to the thermal switches. Most likely, you will have to replace one of them.
Failure of two spirals
Any thermal sweat has two heating spirals, each of which performs its own function. The first is designed to boil water, and the second performs a constant heating of the contents of this unit.
If the breakdown of the thermal sweat occurred due to a malfunction of the heating spirals, then it makes no sense to repair it. This event will take a lot of time and family budget. With a huge number of shortcomings, it is better to buy a new kettle, because replacing all the wires and the tank at the same time will cost a lot of money.
Important! Regardless of the manufacturer’s company and volume, each thermal sweat is equipped with several heating modes, with which anyone can set the optimum temperature for heating the water.
But experts advise to purchase thermal sweets having no more than three heating modes, since this is quite enough for optimal use of the device. The cheapest models of thermos kettles have one mode of heating water. This feature is also worth considering when buying a thermo-kettle.
Why does the thermal sweat not heat water?
The main problem of any thermal sweat is heating water. Often the reasons are any short circuits in the circuit, which includes the heater. Short circuits can occur in the heater itself, relays and fuses. The easiest way to find out is to “ring” each element, as well as all wiring with a multimeter. Using this method, you can easily find out which part needs to be replaced or repaired.
Thermal fuse malfunction
So what role does a thermal fuse play in an electric kettle? This spare part is one of the most necessary in the device device. It protects the device from combustion. If at least one of the fuses stops functioning, then the water stops heating.
Typically, these parts are attached to the side walls of the thermal sweat. But in some models they can be installed on the bottom, and their appearance resembles small cylinders. They begin to work when the water temperature reaches a boiling point. Their role is to turn off the device if there is not enough water in it. If the thermal fuses start to work before the water boils, this can lead to overheating of the thermal stream, and it will not boil, but simply heat the water. To check the health of this appliance, it must be placed in boiling water. And if it turns on before it boils, it will mean that it is faulty and needs to be replaced.
Repair of thermal fuses.
It is necessary to check all the main components of the device with a multimeter. Testing the thermal relay. To do this, the tester must be set to a mode that allows you to measure resistance.
The multimeter shows a complete lack of resistance, which means that it is he who is the main reason why the thermal sweat does not heat water. This means that the sensor must be replaced with a new one. To replace it, you need a curly screwdriver. With its help, it is necessary to unscrew the bolts that secure the sensor, and replace it with a working one.
Important! It should be remembered that the constant temperature of the thermal fuse, in working condition, is about 900FROM.
If after changing the thermal relay thermal sweat began to work in normal mode, it means that the efforts were not in vain and the repair was done successfully.
