- Knob Fault Check
What Is Wrong With the Cooker Knob?
Before booking a repair, identify the exact knob problem. A stuck knob, loose knob, ignition issue, or flame control fault can each have a different cause.

The knob will not turn or feels stuck
If the knob is hard to turn or does not move at all, the issue may be linked to the internal shaft, grease, dirt build-up, or the knob itself.

The knob is loose or comes off
A loose knob can stop the flame from being controlled properly or prevent the knob from sitting correctly on the internal shaft.

The knob turns but the flame does not change
If turning the knob does not increase or reduce the flame, the issue may be linked to gas control, the knob shaft, or internal parts.

The flame goes out after releasing the knob
If the flame only stays on while you hold the knob, the thermocouple or flame safety system may need checking.
Simple Problem Explanation
Why Is the Cooker Knob Not Working?
A cooker knob is not just a simple button. It controls the gas flow, flame level and, on some models, also activates the ignition system. When the knob sticks, becomes loose or stops controlling the flame properly, using the cooker can become difficult and unsafe.
Sometimes the cause is simple, such as grease or dirt around the knob. In other cases, the internal shaft, ignition switch, thermocouple or gas control parts may need checking.
Useful Diagnosis Tip
If only one knob has the problem, that specific control area is usually the place to check first. If several knobs have issues, the fault may be wider.
Common Reasons a Cooker Knob Stops Working

Stuck knob or internal shaft
Grease, dirt build-up or damage to the internal shaft can make the knob hard to turn or completely stuck.

Loose or broken knob
If the knob does not sit correctly on the shaft, the flame may not be controlled properly or no command may be transferred.

Faulty ignition switch
On some cookers, pressing or turning the knob activates the ignition. A fault in this part can stop the burner from lighting.

Thermocouple or flame safety system
If the flame goes out after releasing the knob, the flame safety system or thermocouple may not be working correctly.

Gas flow control issue
If the knob turns but the flame does not change, there may be a fault with the gas control section or an internal connection.
What to Check Before Booking a Repair
Does the knob turn?
Check whether the knob is fully stuck or just difficult to turn.
Is it loose?
If the knob is loose or comes off, it may not be sitting correctly on the shaft.
Does ignition click?
Check whether you hear the ignition clicking when turning or pressing the knob.
Does the flame go out?
If the flame only stays on while holding the knob, the flame safety system may need checking.
Important Safety Note
If the cooker knob is stuck, you smell gas when turning it, the flame cannot be controlled, or the flame goes out after releasing the knob, avoid forcing or repeatedly turning it. Do not open or adjust gas supply parts, gas valves or internal connections yourself.
If there is a gas smell, do not try to light the cooker.
Do not force a stuck cooker knob.
Do not open gas supply parts yourself.
