"It won't light" has about seven causes — work through them in this order and you'll fix it 90% of the time.
Step 1: Is There Gas?
Start with the obvious. Check the level — hot water trick or weigh it. Empty cylinder = no flame, every time.
Step 2: Is the Valve Open?
The cylinder valve needs to be open — anti-clockwise. If it was left closed after the last refill or overnight, that's your answer.
Step 3: Try Another Burner
- Other burner lights → the problem is THIS burner — clogged jet or seated cap. Clean it (cleaning guide).
- No burner lights → it's upstream — valve, regulator, hose, or gas supply.
Step 4: Check the Igniter (Auto-Ignition Cookers)
- No click at all → dead igniter or flat battery (some models) — light manually meanwhile.
- Clicking but no light → spark present but no gas OR clogged jet — clean the jet.
- Igniter greasy → wipe the tip; grease kills sparks.
Step 5: The Regulator
Not seated squarely, reverse-threaded wrong, or failed diaphragm. Reseat it per the connection guide; if it shows failure signs, replace it.
Step 6: The Hose
Kinked, crushed, or rat-chewed. Trace it end to end — straighten kinks; replace damage.
Step 7: The Cap and Head
A burner cap seated crooked blocks gas flow — lift it, centre it, try again.
When It's Something Else
- New cylinder won't flow → valve seal remnant — check the seal is fully peeled off.
- Work done on the cooker → a line may be disconnected — call a technician.
- Still nothing after all this → call us or a technician — don't keep opening gas.
Frequently Asked Questions
Why does it light with a match but not the igniter?
The igniter/spark is the problem — clean the tip or replace the igniter/battery.
Why did it work yesterday but not today?
Overnight clog (a spill overnight), a closed valve, or gas running out — check in that order.
Is it safe to light manually if the igniter is dead?
Yes — use a long-nozzle gas lighter per the lighting guide.
