Home must learn! Gas stove common fault quick solution
**Original Title: Home Must Learn! Quick Solutions to Common Gas Stove Faults**
During autumn and winter, the usage of gas stoves in homes increases significantly. This season also brings a higher risk of gas leaks, especially for older stoves that have been in use for several years. If your stove is near its service limit, it's crucial to be extra cautious. Leaks can occur due to aging pipelines, which greatly increase the risk of danger.
Everyone should take this seriously. If your gas stove malfunctions, always contact authorized after-sales service for repairs. Never attempt to fix it yourself or let unqualified people handle the job. However, as a must-have kitchen appliance, it's essential to understand some common issues and how to address them.

### 1. What is Flame Lift-Off and Flashback?
When a gas stove is working properly, the speed at which gas exits the burner ports matches the combustion speed, resulting in a stable flame. However, if the gas jet speed exceeds the burning speed, the flame becomes unstable and may vibrate—this is known as **flame lift-off**.
If the gas flow continues to increase, the flame can move upward, leading to an unstable burn, erratic flames, or even complete extinguishing—this is called **flashback**.
The danger with these phenomena is that unburned gas can leak into the room, creating toxic or explosive gases that may lead to serious accidents. To prevent this, most gas stoves are equipped with a **flame stabilizer**.
**Causes and Fixes:**
- The damper opening might be too large. Adjust it to a smaller setting.
- High gas pressure could be the issue. For LPG users, ask a professional to adjust the pressure regulator. For piped gas, slightly close the main valve.
- Strong airflow in the kitchen can cause instability. Close windows and doors, or reduce the hood’s suction.
- Mismatched or deformed burner caps may be the cause. Replace any damaged parts and ensure they align correctly with the positioning holes.

### 2. What is Backfire (Tempering)?
Backfire occurs when the gas exiting the burner ports moves slower than the combustion speed. In this case, the flame retracts into the burner, causing incomplete combustion and potentially damaging the system. It often produces a hissing or knocking sound, especially when the gas is turned off.
This issue is more common with coke oven gas compared to natural gas or LPG.
**Causes and Fixes:**
- An overly open air inlet plate can cause excessive primary air, leading to backfire. Adjust the air plate accordingly.
- Blockages in the gas line, pressure regulator, or nozzle can reduce gas flow and trigger backfire. Clean the system and ensure proper ventilation.
- Misaligned or damaged nozzles can also cause backfire. Align the nozzle or replace it if necessary.
- Prolonged use may heat up the burner components, increasing the combustion speed. Turn off the gas, cool the parts, and restart the stove.

### 3. What is a Yellow Flame?
A normal gas flame is light blue. A yellow or red flame indicates incomplete combustion, usually caused by insufficient air supply. This leads to the formation of carbon particles, which burn with a bright yellow color. While it may look like a strong fire, it’s actually weak, inefficient, and harmful to both health and the environment.
**Causes and Fixes:**
- Too much gas and not enough air can cause a yellow flame. Adjust the air inlet to balance the mixture.
- Dirt or rust inside the ejector tube can interfere with gas flow. Clean the tube thoroughly before reinstalling the burner.
- Misalignment between the nozzle and the ejector tube can also lead to a yellow flame. Ensure both are aligned on the same axis.
- When LPG cylinders are nearly empty, heavy components may not vaporize properly, causing a yellow flame. Refill the cylinder promptly.
- For mixed gas systems, fluctuations during peak usage can cause instability. Contact the gas provider for assistance.

In summary, gas stoves are essential in every kitchen, and while they may occasionally malfunction, understanding the basics of their operation and common issues can help you respond quickly and safely. Don’t panic if something goes wrong—identify the problem and take the right action. Stay safe and stay informed!
