A gas stove flame that remains weak even when the valve is fully open is a common problem in households, restaurants, and industrial kitchens. So what are the causes, and how can you fix them quickly and safely? Let’s explore with Ngô Thanh Thanh Co., Ltd.
1. The gas cylinder is almost empty
Cause: After prolonged use, the gas runs low, reducing pressure inside the cylinder, which leads to a weak and unstable flame.
- Solution:
-
Gently lift the gas cylinder to check its weight. If it feels unusually light, the gas is nearly empty.
-
Use up the remaining gas and replace it with a new, full cylinder to restore normal pressure and flame size.
-
2. The gas valve is opened too little
Cause: The gas valve is turned too tight, preventing gas from escaping at sufficient pressure.
Solution:
- Adjust the valve so that gas flows out at an appropriate pressure.
- Avoid turning the valve too tight, which restricts gas flow, or too loose, which may cause gas leakage and pose a safety hazard.
3. The gas hose is bent or clogged
Cause: The hose may be pinched, bent, or clogged due to improper placement or long-term use without replacement.
Solution:
- Inspect the entire gas hose for bends or blockages.
- Straighten any kinks or replace the hose if it is old or damaged.
- For safety, it is recommended to replace gas hoses every 8 to 12 months.
4. The burner head is dirty or the gas ports are clogged
Cause:
- Oil and food residues build up over time.
- Food spills or oil splashes clog the burner ports.
- Lack of regular cleaning.
- The burner head is too old and worn out.
Solution:
- Shut off the gas, remove the burner grates, and lift out the burner head.
- Use a brush and a small needle to clean the gas ports thoroughly.
- If the burner head is too old, replace it to ensure a strong, even flame and efficient gas usage.
5. The gas injector nozzle is clogged
Cause: Prolonged use without periodic cleaning can cause the injector nozzle to become blocked by dirt and residue.
Solution:
- Shut off the gas supply.
- Remove the burner grate, burner head, and use a screwdriver to detach the nozzle assembly.
- Clean the nozzle using a small pin, soapy water, or solvent. Dry it thoroughly before reassembling.
- If you’re unsure, seek help from a qualified technician to ensure safety.
Important Note: If you have checked and resolved all the above issues but the flame remains weak, bring your stove to a trusted maintenance center for professional repair and inspection.
