Home must learn! Gas stove common fault quick solution
**Original Title: Home Must Learn! Quick Solutions for Common Gas Stove Faults**
During the autumn and winter seasons, the usage of gas stoves in homes increases significantly. At this time, gas leaks become more common, especially in older stoves that have been used for several years. Households that are near the maximum lifespan of their appliances should be particularly cautious. Aging pipelines can lead to gas leakage, increasing the risk of danger.
Everyone should be careful. In case of a gas stove malfunction, it's important to contact professional after-sales service for repairs. Never attempt to fix it yourself or hire someone from the street, as this could be extremely dangerous. However, as a basic household necessity, you should know how to identify and troubleshoot common gas stove issues.
1. **What is Flame Lift-off and Flashback?**
When a gas stove is functioning properly, the speed at which gas exits the burner holes matches the burning speed, resulting in a stable flame. However, if the gas jet speed exceeds the burning speed, the flame may vibrate—this is known as flame lift-off. If the gas flow continues to increase, the flame may move upward, become unstable, or even go out completely. This is called flashback. Both phenomena can lead to unburned gas leaking into the room, creating toxic or explosive conditions that pose serious risks. To prevent this, most gas stoves are equipped with a flame stabilizer.
**Causes and Troubleshooting:**
- A large damper opening might cause the flame to lift off. Adjust the damper on the back of the stove to reduce the airflow.
- High gas pressure can also lead to this issue. For liquefied gas cylinders, ask a professional to adjust the pressure regulator. For pipeline gas, slightly close the main gas valve.
- Strong kitchen ventilation may cause the flame to lift off. Close windows and doors slightly, or reduce the hood’s suction.
- A mismatch or deformation of the fire cover can also cause this problem. Replace any deformed parts and ensure the positioning holes align correctly.
2. **What is Backfire?**
Backfire occurs when the gas exiting the burner hole moves slower than the combustion speed, causing the flame to retract into the burner. This disrupts the primary air intake and leads to incomplete combustion. It often produces a hissing sound, followed by noise in the gas pipe near the nozzle. When the valve is suddenly closed, a backfire sound may occur as the flame is extinguished. Coke oven gas is more prone to this issue compared to natural gas or LPG.
**Causes and Troubleshooting:**
- An overly open air plate can cause excessive primary air, leading to backfire. Adjust the air plate to reduce the air intake.
- Blockages in the gas line, pressure regulator, nozzle, or ejector tube can restrict gas flow and cause backfire. Clean these components regularly.
- Nozzle misalignment or irregularity can also lead to backfire. Ensure the nozzle is centered or replace it if necessary.
- Prolonged use may heat up the ejector tube and nozzle, increasing the combustion speed and causing backfire. Turn off the gas, let the parts cool down, and then re-ignite.
3. **What is Yellow Flame?**
A normal gas flame should be light blue. When there's insufficient air, hydrocarbons decompose under high temperature and low oxygen, forming carbon particles that appear as a yellow or red flame. This is known as a yellow flame. Although it may look hot, it actually burns weakly, reduces cooking efficiency, and can damage pots and pollute the air.
**Causes and Troubleshooting:**
- Too much gas and not enough air can cause a yellow flame. Increase the wind deflector opening to allow more air in.
- Rust or debris in the ejector tube can affect gas flow. Clean the ejector thoroughly and reinstall the burner.
- Misalignment between the nozzle and ejector tube can also cause this. Adjust the position so both are aligned on the same axis.
- When using LPG, a nearly empty cylinder may produce a yellow flame due to heavy components not vaporizing properly. Refill the cylinder promptly.
- If you're using a mix of natural gas and LPG, a yellow flame may occur during peak usage. Contact your gas provider for assistance.
In summary, gas stoves are essential kitchen appliances, and malfunctions are inevitable. If something goes wrong, don’t panic—analyze the issue and find the right solution. Regular maintenance and proper use can help avoid many common problems. Stay safe and informed!
