The induction hob is cracked, what should I do?

Today, more and more young housewives prefer a hob to standard gas burners. Which our mothers and grandmothers used for many years. Depending on the panel model, the surface heats up in 3-15 seconds.

But hobs have one unpleasant feature! They can burst, after which it is difficult to use such a technique.

In the article we will analyze the advantages and disadvantages. And what to do if the glass on the hob is cracked.

Causes of damage to the hob surface

If cracks were found on the hob, then this was preceded by the following factors:

A sharp, strong touch to the surface of any objects. For example, you may drop a heavy pan, which is a common cause of glass ceramic failure. The fracture will look like a hole in the center where the impact occurred, and branching cracks.

The stove became very hot due to several burners operating at full power for a long time. Usually the defect appears with a bang and can spread in different directions.

It happens when the stove was installed incorrectly, and the powerful voltage supplied to the equipment destroys the hob. The surface begins to crack from the central part, after which the defects diverge, having sharp corners.

Point damage, for example, a knife falling.

Tearing off dishes that are stuck. For example, a frying pan or saucepan was placed on a sticky, uncleaned cooking surface. When heated, the dishes become glued and can only be torn off with a piece of glass ceramic.

Escaped jam and sugar syrup are very difficult to remove from the stove. When heated sugar comes into contact with the surface, it penetrates into the structure of the glass-ceramic material. When cleaning the slab, the surface is damaged and chips appear.

Important!

The last two reasons are caused by manufacturing defects and non-compliance with the rules when assembling the model. Common cases are when the surface is mounted very close to the edges, and during the heating process it bursts.

It should be remembered that faulty equipment powered by electricity is dangerous for any use. There are rules where safety must be observed:

Any cooking on panels that have cracked should be avoided;
Cleaning products for cooking surfaces must be specially designed;
It is not recommended to touch metal utensils with wet hands, there is a risk of electric shock;
Do-it-yourself repairs may result in a short circuit.

Is it possible to change the glass yourself?

Users ask this question quite often, especially after announcing the cost of repairs. The price is really high, but this is exactly the case when you should not save and it is better to seek the help of a specialist to avoid additional costs. Trying to repair a hob yourself can be difficult for several reasons:

It is impossible to find branded glass that is suitable specifically for your hob without contacting the manufacturer of household appliances. Regular heat-resistant glass for a hob will not work, as it is not designed for the point temperature distribution that characterizes an induction cooker. During operation, tempered glass can not only crack, but also shatter into many pieces. For the hob, it is permissible to use only the original glass-ceramic surface. Sometimes you can find suitable used glass 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? Hobs sold as spare parts have most likely already been subjected to many different loads and have microdamages that will soon lead to glass replacement again.
Replacing a glass-ceramic surface requires special skills, abilities and tools. Without special education, qualifications and experience, you can break panel parts when disassembling it, despite the fact that the list of works may seem simple. If damage appears on the glass of the induction panel, it is best to contact the service center and an experienced and reliable technician. Only the professionalism of the master will ensure the highest quality of the work performed and the shortest possible time for its implementation.

Advantages of qualified hob repairs:

The ability to remotely call a technician, prompt response and carry out diagnostics and repairs at a time convenient for you.
Rich experience of craftsmen, availability of special tools, equipment and work skills.
Providing exclusively original, branded spare parts and components directly from the manufacturer.
Long warranty period for spare parts and work performed. If a spare part installed by a technician breaks down, it will be replaced completely free of charge during the entire warranty period.

Stoves with glass-ceramic cooking surfaces are popular: they have heat indicators, are easy to use, and easy to care for. But often due to severe mechanical damage or prolonged heating, defects such as cracks and scratches occur. The extent of damage can vary - from a barely noticeable crack to cracks that occupy the entire surface area.

If they cause cracks in the glass ceramics during the warranty period, the manufacturer will replace it. This material has undoubted advantages, including strength.

Glass ceramics have other advantages:

high efficiency, since thermal energy is directed strictly vertically;
reduced power consumption;
fast cooling;
adjusting the size of the heated area.

If you follow the instructions for use, damage to glass-ceramic panels rarely occurs.

What to do if there are cracks and scratches on the hob

If the hob is cracked, it is recommended to follow these safety measures:

do not use cooking equipment;
do not touch metal utensils with wet hands - there is a risk of receiving an electric shock;
Do not try to repair the device yourself, so as not to cause a short circuit.

Call a qualified specialist to fix the problem.

Advice. If the warranty period has not expired for household appliances, then contact the service center.

In case of a warranty claim, a technician comes to the house and conducts a visual inspection of the damaged surface. It determines whether the equipment can be repaired. Then the hob is taken away for examination to determine the cause of the malfunction. If a manufacturing defect or breakdown is detected that was not dependent on your actions, the device is replaced with a new one.

If the warranty is no longer valid, then call a specialist from a company center or a private company. They determine whether the damaged surface can be repaired and fix the problem.

Scratches on the hob

A glass hob requires special care. If used incorrectly, scratches will form on its surface. Shallow damage can be removed at home.

Important! Before removing irregularities, the oven is disconnected from the electrical network and allowed to cool to avoid burns.

The following methods are used:

Mix baking soda with water until a paste forms.. Apply it to a soft cloth and wipe the damaged surface in a circular motion. The remaining soda is removed with a paper towel, and the panel is polished dry with a dry cloth.
In the store you can buy cream paste for polishing metal (cream paste “GOI No. 1”, Metal Polish, Doctor Wax, etc.). The product is applied to a cotton pad or soft cloth. Wipe the entire surface with small movements. Residues are removed with a paper towel. If scratches do not disappear, use a brush with soft bristles.

Before using the product on the entire surface, apply it to a small area and check the reaction of the material.

What to do when faced with such a problem

If any defects occur on the surface of the slab, you must seek help from a specialist. If the stove's warranty has not yet expired, then, to some extent, you are lucky. Just in case, take a photo of the defect and go to the service center:

Have a professional come home to inspect the stove and determine if it can be repaired.
If the warranty period has not yet expired, the service center employees can send the slab for examination to find out why the cracks appeared.
If the cause of the breakdown is a manufacturing defect or other reasons that are beyond your control, the service center should either change the glass ceramics or issue a new stove altogether (in some cases a small additional fee will be charged).
If the warranty has already expired, you can seek help from private companies that repair household equipment. Their workers will also be able to determine the causes of cracks and get rid of them.

Please note that if the defect was caused by an impact (i.e. it was your fault), you will have to pay to repair the stove or spend money on a new one. It all depends on how serious the case is. Be careful when working with equipment, and do not forget about the rules for its safe operation!

How to glue a glass door to metal?

One of the aspects of the proper operation of clay stoves or fireplaces is the timely sealing of various leaks, cracks and crevices that can form on their surface and lead to a decrease in the efficiency of the device.

To seal them, a fairly wide variety of different materials can be used, but the most effective and durable among them is a specialized heat-resistant oven sealant. Such substances are presented on the market in a very wide variety and may differ in chemical composition, manufacturer and other parameters.

The need to treat various cracks and cavities that may appear on the masonry that makes up a stove or fireplace is due not only to the fact that in this case the efficiency of the device decreases, but also to safety requirements. If there are unprotected cracks and seams, the draft inside the fireplace may disappear, and the product may ignite.

Internal or external use of specialized heat-resistant furnace sealants allows you to ensure complete sealing of the device and the absence of gas or heat leaks. All such substances are characterized by high heat resistance (withstand operation at temperatures up to 1500 degrees), resistance to fire, as well as various products of fuel combustion.

The vast majority of oven sealants contain silicate components, as well as special reinforcement in the form of fiberglass. Once applied and dried, they form a very durable and fire-resistant joint that can last more than ten years and provides reliable protection against burnout.

When applying furnace sealants, it is necessary to thoroughly clean the edges of the crack from dust and dirt, and also degrease them. The substance can be applied at a temperature not lower than 0 degrees, and its polymerization (hardening) time depends on the brand of material you have chosen. You should know that it is best to use fresh sealants that were manufactured no earlier than three months before their use date. In this case, they will dry the fastest, and the bond strength will be the highest.

Material advantages

Materials such as glass are used on gas, electric and induction panels. It costs more than enameled surfaces, but the price is justified.

Main advantages:

smooth and even surface;
food is prepared quickly, since the panel heats up only in the place where it is currently needed;
easy to clean - fresh stains can be removed with a regular sponge, and old and serious stains can be cleaned with special scrapers;
a wide range of colors, as well as various design solutions, captivate potential customers.

However, this technique is quite fragile. If an object weighing more than two kilograms or any sharp object is dropped onto the hob, it may crack or break. Therefore, to prevent the panel from bursting, it must be carefully and carefully looked after.
