If you buy a cooktop made of glass ceramic, you can save a lot on electricity. In addition, the regulation system of such stoves is so precise that the temperature of burners is regulated very easily. There is a disadvantage of modern technology: induction hobs are made of heat-resistant glass, which can crack under the influence of various factors. Cracks in the glass is the most common cause of stove failure and the only solution is to replace the glass on the hob.

If the glass ceramic is simply scratched, the appearance of the panel suffers, but it is possible to operate the device. Scratches do not affect the functionality of the device, do not pose any threat to humans.

If small scratches appeared on the glass ceramic, they can be removed even with your own hands. To do this, they use improvised means or a special creamy paste. In any case the work is performed after disconnecting equipment from power supply. It is important to make sure that the technique has cooled. Of improvised means suitable baking soda, which is diluted to a pulp state. This mass is applied to a soft cloth, wiping the surface in a circular motion. Next, the panel is cleaned with a paper towel from the remnants of baking soda. Cream paste is used on the same principle.

Is it possible to change the glass yourself

Users often ask this question, especially after hearing the cost of repair. The price is really high, but this is exactly the case when you should not save money and it is better to use the help of a specialist to avoid additional costs. An attempt to repair the hob itself can be difficult for several reasons:

  • To find a branded glass that is suitable for your hob without going to the manufacturer of household appliances is impossible. Regular tempered glass is not suitable for the cooktop, since it is not designed for the spot temperature distribution that characterizes induction cooktops. During operation, tempered glass can not only crack but also break into multiple pieces. Only original glass-ceramic surface is acceptable for the cooktop. Sometimes used glass can be found on classifieds websites. Its use is much cheaper and less dangerous, but where is the guarantee that it will not crack soon, like the previous one? Cooktops sold for parts are likely to have already been subjected to many different stresses and have micro-damage, which will soon lead to the replacement of the glass again.
  • Replacing a glass ceramic hob requires special skills, knowledge and tools. Without special education, qualifications and experience, you can break parts of the panel when you disassemble it, despite the fact that the list of works may seem simple. If your induction hob glass is damaged, our experienced and reliable craftsmen will be at your disposal. Only the professionalism of a master will provide the highest quality of work and the shortest possible time.

The extent of the damage can vary from a small crack to cracks that cover the entire surface area.

Cracked glass on the cooktop. What to do?Kitchen

Cooktops (gas, electric, induction) are made of vitrified clay and tempered glass. Both materials are damaged on impact, the first breaks, the second gets covered with cracks.

Surface damage occurs due to improper use of household appliances:

  • A sharp and heavy blow with a heavy object (e.g. a full pan) causes a splintering which leads to cracks. Such a breakage is typical of vitrified clay.
  • From a pointed blow with a sharp object (knife).
  • If you turn on all the burners on the panel at full power and use them for a long time, the glass overheats and breaks with a crack, the cracks spread across the surface.
  • When dishes are placed on an uncleaned, sticky stove and food is cooked in it, it sticks to the coating under the influence of heat. It can only be torn off with a piece of vitrified clay.
  • Stale or burnt jam is difficult to remove from the hob. Sugar penetrates the structure of the glass ceramic surface. When the dirt is cleaned, it is damaged, chipping is formed.

The cause of damage can be improper installation of appliances. Powerful stress causes its destruction. Cracks form in the center of the surface and spread to the corners.

The resulting damage to the surface:

  • Cause the appliances to malfunction;
  • Warm air escapes through them;
  • Continue to crack, causing the entire surface to break;
  • spoil the appearance of the appliance;
  • Dangerous. there is a risk of electric shock.

  • turn on several burners at full power at the same time;
  • Maintain heat for an extended period of time;
  • Pouring cold water on the heated stove (small splashes do not apply);
  • spill sugar on it, which quickly melts. after cleaning the surface small damages in the material will appear, they easily cause cracks;
  • place the pan on a surface that has not been cleaned, if it sticks, it will come off together with a part of the glass panel;
  • Leave unattended boiling sugar syrup, and even more so. jam, if they overflow over the edge, remove them without micro-injury to the panel is impossible;
  • cook food in aluminum cookware, with a flat or concave, but not convex bottom;

  • glue. silicate, Cosmophen (if the place of damage is not heated above 50 degrees) or cyanoacrylate;
  • silicone;
  • Pieces of glass 4-5×9 cm in size;
  • epoxy resin;
  • Aluminum plate to the size of the crack;
  • rubber spatula;
  • alcohol, gasoline, or acetone for degreasing.
  • Disconnect the stove from the power supply.
  • Remove the panel.
  • Repair begins with a thorough degreasing.
  • Lubricate the crack with glue.
  • Reinforce the surfaces around the perimeter (but not under the burners) with pieces of glass, placing them on the silicone.

Causes of damage to the cooking surface

If breaks are found on the cooktop, it was preceded by such factors:

  • Sharp, strong touch to the surface of any objects. For example, you can drop a heavy pot, which is a common cause of glass ceramic breakage. The break will appear as a hole in the center where the impact occurred, and branching cracks.
  • The cooktop got very hot due to several burners running at full power for a long period of time. The defect usually appears with a crack and can spread in different directions.
  • Occurs when the hob has been improperly installed, and the powerful voltage applied to the technique destroys the cooktop. The surface begins to crack from the central part, after the defects diverge, having sharp corners.
  • Pitting damage, such as dropping a knife.
  • Breaking off dishes that are glued. For example, a pan or pot has been placed on a sticky, uncleaned cooking surface. Cookware sticks when heated and can only be torn off with a shard of glass ceramic.
  • Runaway jam and sugar syrup is very difficult to remove from the stove. Heated sugar penetrates the structure of the glass-ceramic material when in contact with the surface. When cleaning the hob there is damage to the surface, there are chips.

Important! The last two reasons are caused by manufacturing defects and failure to follow the rules when assembling the model. Common cases where the surface is mounted very close to the edges, and in the process of heating it bursts.

  • Means for cleaning cooking surfaces, should be specially designed;
  • It is not recommended to touch metal dishes with wet hands, there is a risk of electric shock;
  • Self-repair can lead to a short circuit.
