The gas stove is the core of cooking in the kitchen. Poor ignition and weak firepower not only delay cooking but also pose a hidden danger of use. Many people encounter such problems and don't know how to solve them. In fact, most of them are caused by improper daily use and maintenance of components. Here we'll help you sort out the reasons and learn simple self-checking and handling methods.

1、Inspection of the gas supply system

1. Gas pressure detection

Normal gas pressure should be 2000-2500Pa (natural gas) or 2800-3200Pa (liquefied gas). Insufficient pressure can lead to reduced firepower, while excessive pressure may cause the flame to escape. A gas pressure gauge can be used for detection. If the pressure is abnormal, contact the gas company for adjustment.

2. Inspect pipes and valves

An aged, bent or loose gas hose can cause poor gas supply. It is recommended to replace the stainless steel bellows every two years and regularly check the joints with soapy water for leaks. Insufficient valve opening can also limit gas flow, so make sure the valve is fully open.

2、Fault Diagnosis of Stove components

1. Ignition system failure

Ignition needle problem: Ignition needle displacement (with a distance of 3-5mm from the burner cap), surface dirt, or aging of internal circuits can cause ignition failure. Clean the surface of the ignition needle with fine sandpaper, adjust the position and retest.

Pulse igniter failure: Frequent ignition may damage the pulse igniter. Tests show that more than five consecutive ignitions should be spaced 30 seconds apart to avoid overheating damage. If the pulse device fails, it should be replaced by a professional.

2. Problems with the combustion system

Burner cap blockage: After prolonged use, the holes in the burner cap can become clogged with oil, causing the flame to disperse and the firepower to weaken. You can use a toothpick to unclog the holes or soak them in hot water with detergent.

Improper damper adjustment: If the damper is too wide open, it will cause the flame to escape; if it is too small, it will produce a yellow flame. Adjust according to the color of the flame: The ideal state is a blue flame. If there is a red or yellow flame, fine-tune the damper clockwise or counterclockwise.

3、Human Factors Engineering Adaptation and Full Life Cycle Usage Specifications for Gas Stoves

1. Standardized ignition operation procedures

The ignition operation should follow the "press - rotate - hold - release" four-step procedure: First, press the knob vertically and rotate counterclockwise to the "ignition" position (corresponding to the valve core opening Angle of approximately 15°), and trigger the pulse igniter simultaneously to produce an electric spark; When a continuous "click" discharge sound is clearly heard and a stable flame is observed, press the knob for 10±1 second to ensure that the thermocouple is fully heated and a stable thermoelectric potential (≥18 mV) is established, thereby maintaining the engagement state of the solenoid valve; Then slowly release the knob to confirm that the flame continues to burn without going out. Do not use non-standard operations such as rapid rotation, multiple short ignitions, or forced turning of the knob, which will cause accelerated mechanical fatigue of the piezoelectric ceramic element and overload of the secondary winding of the pulse transformer. It is measured that the mean time between failures (MTBF) of the ignition system can be reduced by 37% (n=48 units, accelerated life test).

2. Graded cleaning and maintenance system

Implement a three-level maintenance system of daily cleaning - monthly maintenance - quarterly inspection:

(1) Daily cleaning (after each use) : Use a microfiber soft cloth dipped in deionized water (conductivity ≤5 μS/cm) to gently wipe the panel surface to remove grease residue and prevent high-temperature carbonization from forming an insulating layer that affects heat conduction efficiency;

(2) Monthly deep maintenance: Disassemble the burner cap, ignition needle and thermocouple assembly, and use a soft-bristled brush (nylon wire diameter ≤ 0.15mm) to remove carbon deposits and grease from the nozzle aperture (Φ0.3-0.5mm), with a focus on maintaining the distance between the ignition needle tip and the burner cap at 4.0± 0.3mm to avoid electric spark breakdown distance mismatch;

(3) Quarterly battery status check: For pulse igniters powered by built-in dry batteries, use a digital multimeter to measure the open-circuit voltage. When the voltage is less than 1.35V (nominal 1.5V alkaline battery), replace immediately. Insufficient voltage will cause ignition energy attenuation and significantly increase the ignition failure rate.

3.Dynamic matching of thermal load and control of safe operating boundary

Gas stoves are thermodynamically constrained equipment, and their safe operation must strictly follow the design condition constraints:

(1) Do not operate without a pot or with the pot bottom not covering the burning area. Continuous ignition for more than 60 seconds will cause the temperature of the burner head to exceed the limit (> 750 ° C), leading to intergranular corrosion of the stainless steel burner cap and cracking of the ceramic insulation of the ignition needle;

(2) Multi-burner coordinated load management: When all stoves are activated simultaneously, the total heat load must not exceed 90% of the rated value on the nameplate (for example, for a nominal 4.2kW stove, the upper limit of concurrent load for multiple stoves is 3.78kW), otherwise it will cause fluctuations in supply pressure and deviation of the primary air coefficient α from the design value (0.45-0.65). Induce yellow flame, flameout and incomplete combustion (CO emission concentration rises to > 800 ppm);

(3) Load distribution recommendations: Focus scheduling should be based on the heat demand characteristics of the cooking task - for high-power stir-frying operations, prioritize the main focus (rated heat load ≥4.0 kW), and for low-power stewing operations, allocate to the auxiliary focus (rated heat load ≤1.75 kW) to achieve optimal system energy efficiency.

4、Responses to Special Scenarios

1. Gas characteristics in winter

The gas density increases in winter, so the air valve should be adjusted appropriately to ensure complete combustion. If "condensation" occurs, wipe the inside of the stove with a dry cloth to avoid water stains affecting ignition.

2. Aging treatment of stoves

The components of a gas stove will naturally age after 8 to 10 years of use. If you frequently experience unstable flame and difficulty igniting, it is recommended to replace it with a new one. When purchasing, pay attention to choosing products with energy efficiency grade 1, which can improve energy efficiency by more than 30%.

Conclusion:

If your gas stove has problems such as difficulty in igniting or low firepower, don't blindly disassemble and repair it. First, simply check by method and deal with minor faults in a timely manner. Regular cleaning and maintenance can not only restore the normal use of the stove but also ensure cooking safety and enhance the user experience.
