The situation when a gas stove begins to emit an obsessive crackle for no apparent reason is familiar to many home appliance owners. Sound. electric-fireA stain that doesn’t stop even after you’ve removed your hand from the handle or turned off the burner is not only annoying, but also a signal of potential malfunction. Ignore this symptom can not, since a continuous spark can lead to the burnout of the ignition unit or melting of contacts.
The reasons for this behavior of the technique can vary from the banal ingress of water on the panel to a serious breakdown of high-voltage wiring. In most cases, the problem can be solved on your own without resorting to an expensive master call. However, it is necessary to clearly understand the system. ignition and comply with safety regulations when working with gas and electricity.
In this article, we will discuss in detail all possible reasons why fire-fire Click on its own, and provide a step-by-step algorithm of actions to eliminate the malfunction. You will learn how to diagnose, what tools will be needed and in which cases repair with your own hands is impossible.
Principle of operation and the design of the ignition system
To effectively fix a malfunction, you need to understand how the mechanism works. Electrical fire system It is an electrical circuit that converts a standard network voltage into a high-voltage pulse. This pulse skips between the electrode and the burner body, igniting the gas. The key elements here are the transformer, the capacitors and the candles themselves.
In modern models of plates, such as Gefest, Hansa or BoschIt uses an automatic system. This means that the spark is generated only when the handle closing the contact is pressed and turned. If the cracking continues constantly, it indicates that the circuit is closed somewhere else, or the control unit “thinks” that the handle is still pressed.
⚠️ Attention: Before any manipulation of the gas stove, be sure to close the gas supply and disconnect the device from the power grid. Working with high-voltage elements requires special care.
The main node responsible for the generation of sparks is often called ignition. It is he who distributes impulses through candles. If this unit fails, it can chaotically apply voltage to the electrodes, causing a continuous crack even when turned off.
Moisture intake and contact contamination
The most common and easily eliminated cause is moisture. If you have recently washed a stove or brewed a soup that has “run away” on the panel, water may have leaked inside under the handles or into the candle area. Water is a conductor, and until it dries, the current will continue to flow, causing sparkling.
In addition to water, fat and sodium can cause the problem. Over time, on the surface. ceramic It's a conductive layer of fat. This leads to the fact that the spark punches not on the metal dissector, but on the surface of the ceramics, creating a characteristic crack. Visually, this may look like a small blue sparkle on the side of the main electrode.
To eliminate this problem, follow the following steps:
- 🧼 Wash the area around the burners with dry rags, removing visible moisture and fat.
- 💨 Use a dryer to dry hard-to-reach places under the handles, but don't overheat plastic elements.
- 🔍 Check the dryness of the contacts under removable handles, carefully removing them.
- 🧹 Clean the candles from the soda with a soft brush, without using abrasive materials.
Often after a quality drying for several hours, the problem disappears by itself. If, after the full drying of the plate, fire-fire It keeps clicking, so the reason is deeper.
Mechanical damage and oxidation
Constant exposure to high temperatures and aggressive environment leads to wear and tear of materials. Metal contacts are oxidized, and ceramic insulators can crack. A crack on the ceramics is a critical malfunction. Inside the crack, dirt and moisture enters, creating a path for current leakage. In this case, sparkle I'll have to replace it.
Oxidized contacts inside the switch handle can also cause spontaneous switching on. The mechanism of the handle can jam without breaking the contact to the end. Visually, this is difficult to notice, so often it requires disassembly of the node.
How to check the integrity of ceramics?
To check, remove the burner and carefully examine the base of the candle. Look for microcracks or chips. Even a hair on ceramics can cause a breakdown. If a defect is found, the part must be replaced.
Particular attention should be paid to the state of high-voltage wires. If the insulation on them burned or rubbed, the spark can punch on the plate body. This not only causes a constant cracking, but also creates a risk of electric shock when touching metal parts of the device.
Failures of switches and control unit
If external factors are excluded, the problem is most likely to be in the electronics. Switches of the burner modes (cranes) wear out over time. Inside are a spring and a contact group. If the spring is weakened or the contacts are burned, they may remain in a closed position.
Block. ignition - it's the brain of the system. In older plate models, it is a separate board, in newer ones it can be integrated into a common control module. Failure of the capacitor or thyristor on this board leads to the fact that the voltage is supplied to the candles constantly. Repairing such units at home is complicated and requires skills with a soldering iron and multi-metal![WIDGET:poll: How often do you have problems with the gas stove?: Monthly | Once every six months |Rarely, only after cleaning |Never had a problem]
Diagnosis of the block is better carried out by the method of exclusion. If when all candles are turned off, the crackling does not stop, the block itself is defective. If the spark comes from only one particular candle with a working switch, the problem may be in the wiring.
Most often, the cause of endless clicking becomes a faulty switch of power burner or a break on wet ceramics of a candle.
Instructions: Finding and Resolving Faults
To conduct the diagnosis, you will need a minimum set of tools: screwdrivers (cross and flat), multimeter, dry rags and, possibly, a hairdryer. The process of finding a fault should go from simple to complex.
First, make sure the stove is disconnected from the network. Remove the cast iron bars and dissecters. Check the candles for contamination. If there are no visual defects, proceed to check the switches.
☑️ Diagnostic algorithm
Checking the switch is carried out by vertebrating contacts in different positions. In the "off" position, the chain must be opened. If the multimeter shows resistance close to zero, the switch is faulty and requires replacement. The integrity of the wires going to the candles is also checked.
Below is a table that helps classify symptoms and possible causes:
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| One burner clicks. | The switch or candle is faulty | Replacement of a candle or faucet |
| All the burners click. | Faulty ignition unit | Replacement of the control unit |
| Crack after washing | Moisture intrusion | Drying by a phenome |
| Sparks in the side | Cracking on pottery | Candle replacement |
Replacement of elements of the ignition system
If the diagnosis revealed a specific faulty detail, it must be replaced. Candles of ignition are usually mounted on latches or screws under the panel. To replace, you need to remove the top cover of the plate, disconnect the wire and remove the old candle. It is important to install the new part in the same way, keeping a gap between the electrode and the housing (usually 3-4 mm).
Replacing the switch requires a deeper disassembly. You need to remove the front panel or upper cover to get to the crane mounts. When installing a new element, make sure that the wires are connected correctly so as not to confuse the contacts.
⚠️ Warning: When assembling the stove, make sure all wires are securely secured and do not touch the heated parts. Poor contact can cause sparkling inside the body.
The ignition unit changes completely. It can be located under the upper panel or in the lower part of the body, depending on the model. gas-stove. When replacing, it is recommended to photograph the connection of the wires so as not to make a mistake when assembling.
When buying spare parts (candles, switches), be sure to check the article with the original part or use the VIN code of your plate model. Universal parts may not fit in size or type of connector.
Prevention and operation rules
To the system electric-fire It has been working long and trouble-free, follow simple rules of operation. Do not allow the panel to be filled with large amounts of water when cleaning. It is better to use a wet, well-pressed cloth.
Regularly clean the candles from fatty plaque. This can be done with a soft toothbrush soaked in alcohol or a special degreaser. Make sure that food does not burn directly on the electrodes.
If you notice that the spark has become faint or changed color from bright blue to orange, it is a sign of contamination or oxidation. Timely cleaning will prevent more serious breakdowns.
Frequently Asked Questions (FAQ)
Why does the electric fire click when the stove is off?
This happens if the contact is closed in the switch, the insulation of the wire is broken or the relay is "stuck" on the ignition block. Also a common cause is moisture under the handles, creating for current.
Can I use the stove if the electric fire is not working?
Yes, the gas stove can be ignited manually with matches or a lighter, provided that the gas supply is working and the taps open. However, faulty electronics are better repaired.
How much does it cost to replace the ignition unit?
The cost depends on the model of the plate. The block itself can cost from 500 to 2000 rubles. The work of the master is paid separately. In simple models, the replacement can be done independently.
Is it dangerous to continue using a stove with a constantly clicking fire?
It's not recommended. A constant spark can lead to overheating and ignition of fat deposits inside the stove, as well as to the final failure of an expensive control unit.
