1 Gas tank is about to run out
The main reason for the weak fire on a gas stove is that the gas tank is about to run out. This occurs when the gas is used for a long time and not replaced, resulting in insufficient gas supply. As the gas tank nears empty, the suction pressure decreases, leading to a smaller flame.
How to Fix:
- Check the weight of the gas tank by lifting it slightly. If it feels light, it indicates that the gas is running low.
- Use up all the gas in the tank and replace it with a new one to resolve the issue.
2 Gas tank valve opened too little
The gas cylinder valve may be opened too little due to tightening it excessively, preventing the gas from escaping with sufficient pressure.
How to Fix:
- Adjust the gas cylinder valve to release gas at a moderate pressure.
- Avoid tightening the valve too much, as it limits the gas pressure. Additionally, ensure it is not too loose as this can cause gas to escape into the environment, posing a safety risk.
3 Gas pipes are folded or blocked
The gas pipe can become bent or blocked due to prolonged use without replacement.
How to Fix:
- Inspect the gas pipe for bends, blockages, or damages.
- If the pipe is bent or blocked, straighten it.
- If the pipe is old, replace it to ensure safety and improve gas flow.
- It is recommended to replace the gas hose every 8 to 12 months.
4 Burner is dirty, fire outlet is blocked
Dirty burners and blocked fire outlets can occur due to excess grease accumulation, spilling of food or grease during cooking, lack of regular cleaning, or an old burner causing blockage.
How to Fix:
- Lock the gas and remove the stove bracket, then clean the fire exit slots using a brush and sharp needle.
- If the gas stove’s burner is too old, replace it with a new one for improved flame strength and gas efficiency.
5 Choking gas injectors
If the gas stove still has a weak flame after checking the above causes, it is recommended to check the gas injectors for clogs. Clogged injectors can result from long-term use without regular cleaning.
How to Fix:
- If not experienced, seek the assistance of a professional repairman to safely remove and clean the gas injectors.
- If knowledgeable, lock the gas, remove the stove bracket and burner, and then use a screw to remove the pipe assembly and wind adjustment lever below the burner. Clean the components using a needle, soap, gasoline, and dry them before reinstalling.
If the small flame issue persists after attempting the above fixes, it is advised to bring the gas stove to a repair center for prompt and safe resolution.
