Symptoms
If you notice one or more of these symptoms, this page is for you:
- The stove won't light when you turn the knob
- Auto-ignition sparks but the burner does not light
- Gas smell before the burner lights (knob turned, no flame)
- Only one burner fails to light, the rest work
- The whole stove suddenly stops igniting
The most common causes
1
Blocked burner ports (most common)
Grease and food buildup block the gas ports in the burner. The fix: a deep clean. This accounts for around 60% of cases.
2
Faulty auto-ignition
The ignition sensor or its electrical circuit has failed.
3
Faulty safety sensor (thermocouple)
The sensor shuts off gas automatically if it detects no flame. If faulty, it shuts off gas even while the burner is lit.
4
Low gas pressure
A weak regulator, a nearly-empty cylinder, or low natural-gas pressure.
5
Blocked or kinked gas hose
The hose between the cylinder and the stove is kinked or blocked.
6
Faulty burner knob
The knob turns without actually opening the gas.
