Fix Gas Stove Flame Problems: Troubleshooting Guide

Gas stove flame problems disrupt cooking and raise safety concerns. Whether you're dealing with weak flames, unusual colours, or uneven burning, most issues stem from simple maintenance problems that you can resolve yourself. Understanding the root causes helps you fix issues quickly.

Normal Gas Stove Flames

A properly functioning gas stove produces steady blue flames with minimal yellow tips. Blue flames indicate complete combustion and optimal efficiency. The flame should be uniform in height and burn quietly without sputtering.

Yellow or orange flames signal incomplete combustion, which reduces cooking efficiency and may produce carbon monoxide.

Common Gas Stove Flame Problems and Solutions

Weak or Low Flame

Weak flames make cooking slow and inefficient. Gas flow restriction or blocked burner components typically cause this problem.

Main causes:

• Clogged burner ports from food spills and grease
• Low gas pressure from faulty regulators or empty cylinders
• Blocked gas jets or orifices

Solutions:

Turn off the gas supply and allow the burner to cool. Remove burner caps and grates. Soak burner heads in warm soapy water for 15-20 minutes with baking soda to break down grease.

Use a soft-bristled toothbrush to scrub burner ports thoroughly. For stubborn blockages, use a thin wire to carefully clear each port.

Check your LPG cylinder gauge and replace it if low. Inspect the gas regulator for damage. Contact a certified technician for regulator replacement.

Yellow or Orange Flames

Yellow or orange flames indicate an improper air-to-gas mixture, leading to incomplete combustion and sooty residue on cookware.

Main causes:

• Insufficient air mixing with the gas
• Dirty or misaligned burner caps
• Blocked air intake shutters
• Incorrect air shutter adjustment

Solutions:

Clean the burner caps and heads thoroughly. Check the burner cap alignment and reposition it correctly on the burner base. An improperly seated cap disrupts gas flow patterns.

Locate the air shutter beneath your burner. Adjust it gradually while observing the flame colour. Open the shutter slowly until the flame turns blue. For LPG gas, keep it half open. For natural gas, adjust to one-quarter open.

Uneven Flames

When one side of the burner produces a high flame while the other barely flickers, burner positioning or blockage causes the issue.

Main causes:

• Misaligned burner cap
• Partially blocked burner ports on one side
• Uneven debris buildup around the burner ring

Solutions:

Remove the burner cap and examine its position. The cap must sit centred and level. Clean the burner ports systematically around the entire ring. Use a wire brush or needle to clear each opening. Wipe away any moisture and allow the burner to dry completely before reassembling.

Burner Won't Ignite

Ignition problems prevent your stove from lighting even when the gas flows properly.

Main causes:

• Dirty or wet igniter electrode
• Food debris is blocking the igniter spark gap
• Moisture from cleaning or spills
• Faulty ignition switch

Solutions:

Disconnect the stove from electrical power. Remove the burner cap and grate to access the igniter. Use a dry cloth to clean the igniter electrode thoroughly. Clear any food particles or debris from around the igniter using a soft brush.

Allow all components to dry completely before reconnecting power and testing. If the igniter still fails after cleaning, it needs professional replacement. Check flame failure device safety features.

Continuous Clicking Sound

When the igniter keeps clicking even after the flame lights, moisture or sensor problems are involved.

Main causes:

• Water or moisture on the igniter
• Loose burner cap
• Food debris is interfering with ignition

Solutions:

Check that the burner cap is properly positioned. Clean any moisture from the stovetop surface using a dry cloth, paying special attention to areas around the igniter.

Remove food particles stuck near the igniter using a paper clip or thin wire. Allow the stove to air dry for 30 minutes if moisture persists.

Safety Warnings

Safety must be your top priority when troubleshooting gas stove problems. Always turn off the gas supply valve before performing any cleaning or maintenance. Allow burners to cool completely before touching components.

Never use flammable cleaning products near your gas stove. Use only mild dish soap, baking soda, and water. Avoid abrasive scrubbers that might damage burner surfaces.

Glen gas stoves include an FFD (Flame Failure Device) that automatically cuts the gas supply if the flame extinguishes unexpectedly. If you smell gas, immediately turn off the gas supply at the cylinder, open windows for ventilation, avoid using electrical switches, and evacuate the area. Contact a certified technician before using the stove again.

When to Call a Professional

• Persistent gas odours even when the stove is turned off
• Flames that won't stay lit despite thorough cleaning
• Unusual hissing sounds from gas connections or the regulator
• Visible damage to gas lines, valves, or internal components
• Igniter problems that persist after cleaning

Professional technicians have specialised tools and training to safely diagnose complex gas appliance issues.

How to Maintain Your Gas Stove 

Regular maintenance prevents most flame problems before they develop. Clean your gas stove burners weekly by wiping away food spills and grease. Perform a deep cleaning monthly by soaking burner caps and heads.

Inspect burner caps for proper alignment each time you clean. Check your gas cylinder gauge regularly and replace cylinders before they run empty. Schedule annual professional inspections to identify potential issues before they cause problems.
