How to repair gas stove burner flame being too low

This is happen to me before, my gas stove has low flame problem. I called service center to repair the gas stove. When the repair man worked, I watch him clean the stove and pay attention to a particular job that actually solved the low flame burner problem. With that and further information from the internet, I am confident I can do the repair by myself.

The Problem : The burner port or nozzle is clogged

The gas port or nozzle is not delivering gas seamlessly to the burner. The burner port is small hole located in the middle of gas burner base. The low flame problem occur when this hole has been cover by grease or something. This is blocking or clogging the gas flow to the burner. 

The Solution : Clean burner port or nozzle.

You need to clean this grease with something tin, small and strong. To do that you can use straight pin, needle or small gauge wire.

Cleaning Procedure :

Safety first. Turn off the gas flow to the stove. Make sure the gas regulator turn off or you can disconnected it off the gas tank.

Now lets work on the burner. open the cap burner and the spreader. clean the cap and spreader from grease. look for the burner port or nozzle. On standar burner you will likely see the port in the base of the burner (at the center). sometime it is difficult to see the hole because it cover with grease, so look closely it is there.

Typical Gas Burner

Use the straight pin, needle or small gauge wire. Put it into the the port or nozzle. Push around gently until the port loosen and free of blocking material or grease. Caution. Do not overdone it. Clean the clogged port only to remove things that block the gas flow. Do not try to enlarge or distort the port or nozzle because this will lead to unstable flame. The size of burner port is vary so you better use the smallest straight pin, needle or small gauge wire to fit all the port size.


Put everything back in. Fit the spreader and cap burner properly at it place. Burner cap and spreader should also fit flush with burner base and have very little side to side movement.
Reinstall Burner Cap Correctly

When everything set in place. Turn on or connect the gas regulator again. Turn the ignition on. The flame should now bigger and burn better then before. 

That it . Done

Attention / Caution :
  • Do not use a wooden stuff like tooth pick and such because it can break off and felt into the port or nozzle (difficult to remove) and prevent gas flow properly.
  • Do not clean the port or nozzle using detergen. Detergen can clog the gas port.
  • Again, Do not overdone it. Clean the clogged port only to remove things that block the gas flow. Do not try to enlarge or distort the port or nozzle because this will lead to unstable flame
  • Always clean the burner cap after a spill over and routinely clean the burner caps. A clean burner cap will help avoid poor ignition and uneven flame.
