Gas Range & Cooktop - Common Causes for Slow Ignition, No Ignition or Clicking on Surface Burners. Gas surface burners are often slow to light or will not light at all because the burner or burners are wet or dirty, the electrode is not seated properly or the burner head and cap are not matched up properly.
Over time, cooking food with grease and other particles can clog a tiny little hole that prevents the gas from getting to the ignitor. Using a simple small paper clip or compressed air, you can clear out this little hole which allows the gas to reach the ignitor and light.
Cause: Potential issues include a closed gas valve, a kink in the gas supply line, or even a leak. How to Troubleshoot and Fix: Ensure the gas supply valve is in the 'ON' position. Inspect the gas line for any visible kinks or damage.
Most likely the ignitor is burned out. This is the most common issue on gas ovens. If the ignitor is bad, then order and replace it. I will provide a link to the part and video below. If you get a circuit through the ignitor, and it still will not work, then you most likely have a bad control board.
There are many possible reasons why the burner will not stay lit - the gas jet may be blocked, the valve may be set too low, the air flow may be restricted, there may be an issue with the pilot light, and so on.
If You Smell Gas but Your Stove Is Off, Leave and Call 911
But when you check your stove, you notice that all of the burners are off. In that case, you might have a gas leak. If so, leave immediately, and call 911 or your local gas company.
Turn off the gas supply, press the ignition button and you should be able to hear a 'clicking' sound. You will also be able to observe a spark, if it is working correctly. If not, a new igniter will need to be purchased. But before you do that, clean the igniter; sometimes, it is just clogged with muck and dirt.
A gas oven igniter replacement costs $150 to $325 on average, depending on the brand and model. A new oven igniter costs $20 to $50 for the part alone. A broken igniter results in the oven not heating, clicking noises without lighting the gas, and gas leaks.
Issues with the Igniter
Listen for a clicking sound when you turn on the oven. If you don't hear it, the igniter may be faulty and need replacement. To replace the igniter, turn off the gas supply, remove the burner cover, disconnect the wires, and install the new igniter following the manufacturer's guidelines.
During a power outage, gas can flow to the burner but the burner can't make that spark to light it. However, you can still light the surface burner manually. Hold a lighted match next to the burner and then turn the knob to the "Lo" position to light it.
Make sure that the igniter is making a clicking noise when you press the igniter button. If it doesn't click, then the wires may not be connected properly, the battery may be dead or installed incorrectly, or the igniter module may have failed.

Gas surface burners are often slow to light or will not light at all because the burner or burners are wet or dirty, the electrode is not seated properly or the burner head and cap are not matched up properly.
There are several issues that could affect your boiler and cause it to stop igniting, such as faulty fan or gas valve, frozen pipes and others discussed in the following section. Try checking if your gas oven or hobs are turning on to check if your home has a sufficient supply.
Turn the circuit breaker to the OFF position. Wait one minute, then turn the breaker back to the ON position to reset electronic oven controls on models so equipped. We suggest doing this even if the light or the clock on the Range or Wall Oven is working.
The rule of thumb is that if repair costs exceed 50% of the price to install a new oven, you should buy a new oven instead of replacing it. For example, if your oven costs $2,000 but costs $1,500 to repair, you could use that $1,500 for a new and improved oven.
Whether it's grease buildup or food crumbs, one of the most common causes for a gas burner that has trouble igniting is debris blocking gas flow to the igniter. The fix: Begin by removing the grate covering the troubled burner. Next, remove the burner cap, which should lift off with ease.
The number 1 failure preventing a gas oven from heating is a weak igniter. The igniter won't get hot enough to allow adequate current to flow to the safety valve so the valve won't open to let gas flow to the burner for ignition. That's why we recommend testing the oven igniter first.
Clogged Gas Feed
If you hear clicking and see sparks as you turn the burner knob, and can smell that gas is flowing okay, but the fire won't ignite, it's possible that the gas feed is clogged.
There are many reasons why a gas stove would stop working, such as the gas or power going out, food debris clogging the igniter, or a broken spark module. Schedule a service professional to assess your gas stove.
Gas Fireplace Igniter Isn't Sparking
If your pilot is lit and the fireplace isn't igniting when you push the button or flip the switch, the igniter may be dirty or defective. Clear away any dirt or debris that may be in the way between the igniter and thermocouple or thermopile.
