A low or weak flame is one of the most common problems gas stove users face. Cooking slows down, food takes longer to heat, and gas consumption increases. Instead of panicking or calling a technician immediately, you can follow some simple steps at home to fix gas stove flame problems. Many low-flame issues come from blockages, moisture, or pressure imbalance and don’t require complicated repair.
This guide explains real causes and simple solutions so you can avoid unnecessary service charges. However, for complex problems professional gas stove repair may be required.
🔥 Common Causes of Low Flame on a Gas Stove
1. Blocked Burner Holes
Food spills, oil and dirt block tiny burner ports, restricting gas flow.
2. Moisture Inside Burner
Water from cleaning can block ignition and reduce flame pressure.
3. Jet Nozzle Blockage
The nozzle inside the burner gets clogged due to dust or carbon.
4. Gas Pressure Too Low
Weak LPG flow or nearly empty cylinder reduces flame output.
5. Misaligned Burner Cap
Incorrect placement interrupts proper air–gas mixture.
6. Air Shutter Misadjusted
Wrong airflow causes weak or yellow flame.
7. Clogged Regulator or Pipe
Dust or debris reduces gas pressure through the inlet pipe.
🔧 Easy Home Fixes for Low Flame Problem
✔ 1. Clean Burner Ports
- Remove burner
- Wash with warm water + detergent
- Clean holes with a needle
- Dry completely before use
This alone fixes 70% low-flame problems.
✔ 2. Clean Jet Nozzle
Use a thin pin and gently clean the jet under the burner.
✔ 3. Check Cylinder & Gas Pressure
- Ensure valve is fully open
- Try swapping regulator if available
✔ 4. Align Burner Cap Correctly
Place it flat and evenly — you’ll see flame improve instantly.
✔ 5. Adjust the Air Shutter
Rotate the shutter below burner until flame turns blue.
✔ 6. Remove Moisture
Heat the burner on low flame or leave under sunlight for 20–30 minutes.
