Electric ignition on gas stove does not work
A common attribute of a modern gas stove is electric ignition using a piezoelectric element. Using matches to light a burner is inconvenient and can cause burns. The presence of electric ignition makes the stove safe and easy to use.

What to do if the electric ignition does not work
Modern equipment for a gas stove sometimes breaks down. If you find problems with the electrical ignition, do not rush to call a technician. It makes sense to try to find the problem yourself and fix it.
Symptoms, signs of failure
Confirmation of failure of the electrical function is:
- pressing the button is accompanied by turning off the automatic power supply of the apartment or house;
- after turning off the control button, the piezoelectric element continues to work and does not turn off, while the gas is ignited;
- When you turn on you hear clicks, the automation works, but the gas does not ignite;
- activating the function with a separate button or turning the knob does not ignite the escaping gas, no clicks are heard;
- when pressed, a spark appears, but the gas does not ignite;
- The piezoelectric element turns on randomly when the burner is on.
The appearance of these or similar symptoms in the operation of an electrical function indicates the presence of a malfunction. It appears unexpectedly and requires immediate elimination for ease of use of the stove.
Possible causes of failure
To troubleshoot the problem, it is necessary to identify the reason why the electric ignition does not work:
- in the event of a short circuit, oxidation of the contacts has occurred, and the presence of carbon deposits does not allow normal use of this function;
- silicon spark plug defect – it may have a crack or damage to the insulation;
- malfunction of the transformer, which is designed to generate spark current;
- presence of grease or moisture inside the ignition system;
- system power supply failure.
ATTENTION! Wet cleaning of a gas stove may cause a malfunction of the electric option. To prevent this from happening, it is not recommended to use large amounts of water when servicing the stove.
How to repair a piezoelectric element
To troubleshoot the problem yourself, you need to find out the cause, and then begin to eliminate it.
Finding out the cause
Often you have to deal with the fact that the electric ignition of one burner does not work. This means that troubleshooting must be carried out along the path of the electric current to the faulty piezoelectric element.
First of all, an external inspection is carried out. The presence of foreign objects on the contact surface must be excluded.
ATTENTION! When inspecting the ceramic surface of an element, it is advisable to use a magnifying glass to confirm the absence or presence of cracks.
If the piezoelectric element is working and the gas does not ignite, turn on the burner using another fire source and carefully monitor the combustion process. If the fire is dim or has a yellowish tint, then the cause of the malfunction is poor-quality mixture formation, due to the need to service the gas supply channels and burners.
A defect identified during inspection is eliminated by replacing the broken element.A tester is used to detect hidden faults in the electrical wiring of a gas stove. By measuring the voltage at the moment the button is turned on, the operability of the tested section of the circuit or control unit and the current coming out of it are determined.
Carrying out repairs
After inspecting the accessible elements from the outside and the need arises to examine the inside of the slab and carry out repairs, it is necessary:
- Remove the top cover of the stove or gain access to the lower part of the hob, embedded in the kitchen furniture.
- After diagnostics have been carried out and a faulty piezoelectric element has been identified, it is unscrewed from the inside of the hob. To do this, sometimes light tapping with a wooden object is required so as not to damage the ceramic body.
IMPORTANT! Before removing the spark-producing element, you need to check the tightness of contact with the network. The malfunction may be due to oxidation of the contact surfaces.
- Now you need to replace the piezoelectric element with a new one and insert it into its original place.
After installation, check the functionality of the slab and secure everything in its original places.
ATTENTION! The cause of malfunction of the spark-producing element is often grease on its contacts. To eliminate this deficiency, you need to clean these surfaces with sandpaper.
If a malfunction is detected in the control unit or contact wires, the faulty parts are replaced, and then the operation of the stove is checked.
Security measures
When carrying out work to disassemble the upper part of the stove or hob, it is necessary to turn off the electricity, then turn off the gas supply.When checking the operability of the stove in disassembled form after repairs, the connection of electricity and gas is carried out in a short-term mode. Full connection of the slab to the required communications is carried out after completion of all assembly work.
Having the skills to work with a screwdriver and an electrical tester, anyone can independently identify and repair damage to a hob with electric ignition. The performance of household appliances is the key to a good mood, especially after performing repairs with your own hands.
