So, during the ironing process you inserted the plug into the socket, but after a few minutes you realized that the iron was not heating up. In this case, it is not necessary to throw away the equipment and go to the store for a new one, because... Sometimes the cause of a breakdown is quite simple and does not require professional skills in repairing electrical appliances. Next, we will look at what to do if the iron stops heating, as well as how to repair existing damage with your own hands.
First, you must visually inspect the case for cracks, defects and traces of melting of the case. Perhaps the appearance will immediately show what exactly is causing the iron to break down. If the inspection does not yield anything, you need to completely disassemble the case to independently diagnose all the components.
Please note that disassembling the iron is sometimes quite difficult. This is due to the fact that every year manufacturers spend more time on the design of electrical appliances, creating invisible fasteners and holes for screws. Initially, prepare a set of screwdrivers and a knife that will be useful to you for further actions.

Power cord
One of the main malfunctions of the iron is the power cord, which you actually plug into the outlet. 
Get to the junction of the contacts with the heating element and if there are no visible faults, use a tester to ring the cord to determine its functionality. 
For dialing, you can use a homemade tester, consisting of a piece of wire, a battery and a light bulb. If the light comes on when the contacts are connected to both ends of the cord, move on.
If the power cord is the cause of the breakdown, you can try to shorten it by 10-15 cm (perhaps the problem area will be removed). Is your iron still not working? Replace the cord with a new one!
Temperature regulator
Second in line is the thermostat. We also check it using a continuity tester, which we attach to the contact group.
When the temperature control is turned toward the circuit closing direction, the electrical circuit should function. Is the light not on? We clean the contacts with sandpaper and check again. We immediately recommend watching the video repair instructions:

The thermostat is working, but the iron does not heat up? Let's start checking the thermal fuse!
Thermal fuse
More often than the power cord, this element of the circuit fails. Its main purpose is to disconnect the electrical circuit if the temperature of the heating element exceeds the nominal value. 
If the heating element is connected to the soleplate using tips, you can try to repair the iron yourself by cleaning the contacts with sandpaper. Still not heating up? We send the equipment for recycling, because... a new part costs almost the full cost of the device!
Please note that if you throw the equipment in the trash, it would be better to disconnect the power cord and keep it for yourself. Perhaps this element will be useful to you in subsequent repairs, especially since it will not take up much space in the closet!
Steaming system
If the malfunction is that the iron’s steamer does not work, then most likely it is necessary to clean the internal steam cavities. To do this, we recommend that you use a solution of water and vinegar in a ratio of 1 liter to 1 glass. Place the sole in a container (as shown in the picture), bring the water to a boil on the stove, turn it off and wait until it cools down. After this, we repeat the action 3 more times, which is enough to properly clean the spray bottle.
That's all the instructions for repairing an iron with your own hands. As you can see, the event is quite simple and even a novice electrician can do it! Finally, I would like to note that if the red indicator on the case is blinking, do not panic, because this may indicate a certain operating mode or automatic shutdown after heating. Read the instructions that come with the kit to understand the reason for the blinking.
