What Type of Burner Problem Do You Have?
Use the circular fault guide below to identify the most likely burner issue before booking a gas cooker repair in London.

One Burner Will Not Light
If the other burners work, the fault is usually connected to that burner or its ignition point.

Weak Burner Flame
A short or weak flame can be caused by a blocked burner, grease or incorrectly seated burner parts.

Spark But No Flame
If there is a spark but no flame, gas may not be reaching the burner correctly.

Flame Goes Out
If the burner lights and then goes out, the thermocouple or safety system may need checking.
Simple Problem Explanation
Why Is One Gas Cooker Burner Not Working?
When only one gas cooker burner is not working, the problem is usually local to that burner. Common causes include blocked burner holes, dirt around the flame area, moisture after cleaning, a burner cap that is not seated correctly or a faulty ignition point for that specific burner.
If all burners are affected, the issue may be wider. But if only one burner will not light or has a weak flame, checking that burner, cap, ignition electrode, control knob and thermocouple can help identify the most likely cause.
Common Reasons a Gas Cooker Burner Stops Working
Blocked Burner
Grease or food residue can block the burner holes.
Misplaced Cap

Ignition Point
The ignition electrode for that burner may be weak or faulty.
Control Knob
A stuck or faulty knob may stop gas from reaching the burner.
Thermocouple
If the flame goes out, the safety system may need checking.
What to Check Before Booking a Repair

If one gas cooker burner is not working and you can smell gas, do not keep trying to light the burner repeatedly. Do not open or adjust gas supply parts, gas valves or internal connections yourself.
Treat any gas smell seriously.
Do not open gas supply parts.
If the flame keeps going out, stop using it.
