A gas oven igniter both lights the gas and tells the valve to open. A weak one clicks or glows but never ignites.
Understand the Weak-Igniter Failure
As igniters age they draw too little current to open the safety valve.
Fix: It may glow orange but never reach the temperature needed — replacement is the fix.
Rule Out Gas Supply
No gas at all will also prevent lighting.
Fix: Confirm other gas appliances work and the oven's shutoff valve is open.
Replace the Igniter
The igniter is a wear part with a finite life.
Fix: A technician swaps it in well under an hour on most ranges.
