We fix inoperative electric ignition on the gas stove
On many models of gas stoves, designers set an automatic ignition, which is activated with gas supply or from a separate button. This function is very convenient: you do not need to contact with open fire in order to light the burner. If you suddenly find that the automatic ignition on the gas stove does not work, do not rush to call the service: it is quite possible to carry out the repair of this fault with your own hands.
Symptoms
Specialists in gas stoves on the basis of the collected statistics compiled an approximate register of frequently encountered failures.
- When pressing the burner control knob or a special separate electric ignition button does not occur.
- Automation products in the gas stove works constantly, audible clicksbut no spark - no gas ignites.
- After releasing the button or knob, the system does not turn off.
- The device continues to operate constantly, even when the button is not pressed.
- Knocks machine protection in the apartment panel at startup.
- Closed piezoelectric ignition or electric firing plate.
How it works
Electric ignition can only be used on gas stoves. Its main function is to burn blue fuel at the moment of its exit from burner splitterinstalled on a gas stove. He happens automatic and mechanical type. In the first variant, the special piezoelectric elements set fire to the gas-air mixture when the switch is turned on the control panel, and in the second case, the user must press a special button. From a spark, the gas ignites and you can start cooking. The device of automatic ignition of gas is the most whimsical and unreliable device from all arsenal with which the modern gas stove is equipped.
Very important! Never try to turn on the system if the burners are removed - breakdown on the case is guaranteed.
In the aggregate, the whole work of this system looks like this:
- the user presses a button, thereby he energizes the capacitor, which starts charging;
- the level on the thyristor gradually grows, when it reaches the set threshold, the capacitor discharges;
- at the output of the entire system, a voltage arises, which actuates a special device - a spark gap;
- spark ignites gas.
The whole system works much faster than we talk about it. A spark is fed to the burner, which is currently on (in older models, it was applied to all devices, but where the gas access was opened). Start buttons are located under the controls. Electric ignition powered by the network with alternating current of 220 volts and vulnerable to voltage surges that occur quite often. After a power surge, he can constantly click, which reports his breakdown.
The system will work only if the plug of a separate cable is connected to the home electrical network, which many users forget and call the service with complaints.
Causes of failure
Why does the electric ignition of the gas stove not work? There are several causes of a malfunction in this device.
- There is no spark on the electrodes.
- Moisture or grease has fallen on the inside of the system or on the surface of the candle.
- A crack has appeared or the insulation of a candle made of ceramic has burst.
- Blown transformer - spark generation unit.
- The contacts of the power button were oxidized or a deposit was formed on them as a result of a short-circuit fault (short circuit).
Some malfunctions may occur after wet cleaning the hobwhen moisture gets into the inside of the stove. To eliminate them, it is enough to make preventive measures: cleaning the contacts, drying the candles - practically the same measures are made by motorists.
If only one burner does not ignite, the reason may be damage to the high-voltage wire to the ignition electrode, the ignition device itself, or the failure of the channel of the entire unit.
Making repairs
When you have inspected, found out the reason and diagnosed the malfunction - you can proceed to self-repair gas stove. It is carried out similarly for all models. The famous Italian brand Ariston or the Belarusian stove Hephaestus, which is in great demand among the Russians - there is no difference, the ignition systems are almost identical except for purely individual nuances.
Before starting work, refresh your knowledge by reading the product instruction manual. Knowledge of the principle of work and gas stove devices necessary for its successful repair.
- We set fire to a faulty burner using a third-party open flame source, matches, or special lighter - the flame must be even and distributed around the entire circumference of the divider. Flame Yellow means the wrong concentration of gas and air: you need to clean the nozzle or replace it. It is possible that the divider clogged holes or moisture got there. It is necessary to make prophylaxis, blow all the holes, remove the burner body and inspect it.
- All electrodes and switches are connected in parallel. Each electrode is powered by a single ignition unit, but they are turned on from different buttons. To make sure that only this button does not work, and the control unit is normal, it is necessary to turn on the next ring. If gas is ignited - repair button, and everything else in the system is working properly.
- If the ignition device cracks constantly, then it is necessary check contacts - they could stick with the ingress of fat or as a result of oxidation carbon deposits formed. Before repair, do not forget to unplug the stove from the network, then carefully disassemble, clean the contacts or dry them with a hair dryer.Compliance with safety requirements will protect you from injury.
Most of the failures that led to the failure can be repaired by yourself - they are not dangerous for the user, but it must be remembered that gas stoves are potentially dangerous products, so even maintenance work must be carried out carefully.
Sometimes the failure of the ignition button leads to the fact that the repair does not help - a complete replacement is necessary. In this case, it is better to go through special shops and buy a similar option.
