No Spark: Turn off the gas and test the ignition button on your cooker. If there is no clicking sound and you cannot see any sparks, then your igniter will need to be replaced.
The Spark Module Is Broken
The spark module provides power to the igniter, which lights the stove. When it's broken or not functioning properly, you probably won't hear the stove clicking and have no spark.
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.
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.
Use a toothbrush and clean the burner bases completely and dry them if they are wet with a hair dryer until they are completely drain. Next, sand the tip of the spark igniter with fine sand paper until it shines again. Now place the cap back on the burner and make sure it's seated flush. Try the burner again.
The possible reasons your oven is not working may include a broken baking or broiling element, a malfunctioning spark element (spark electrode), a broken igniter, a blown fuse, an issue with the control board, or outlets not providing enough power to the oven.
The most common reason a gas stove won't light is that the igniter is clogged with debris. Over time, dirt and dust can accumulate on the igniter and prevent it from sparking. If this is the case, you'll need to clean it off in order for the stove to work properly.
Use a grill lighter or long match to light the pilot light valve at the bottom of the oven. Some ovens are designed to be manually lit at each use. In this case, slowly turn the temperature knob while holding the flame to the pilot light valve. Close the oven door after the pilot light ignites.
Igniter. You'll pay $150 to $250 to repair the igniter. Igniters are crucial parts of gas ovens, as they are responsible for igniting the gas to give heat and cook your food. So, if the igniter is faulty, the oven simply won't heat, but it's dangerous, too, because it can result in gas leaks.
If there is no clicking sound and you cannot see any sparks, then your igniter will need to be replaced.
Reset The Furnace Ignitor
Find the burner door on the furnace and look behind it to find the ignitor. Turn it to “OFF” and wait for five minutes. After you wait, turn it back on and return the door to the burner. It is important to make sure the switch on the door is properly engaged.
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.
A spark igniter electrode is made of metal and the base of the igniter is ceramic. This ceramic base can withstand the high temperatures put out by the burners. The ceramic is fragile and over time may crack or may have other damages and it may be shorting to ground and unable to ignite the gas flame.
If it clicks and sparks but the burner isn't putting gas through, then you need a new safety gas valve. If it clicks but you see no spark then you have a bad DSI board and the DSI (direct spark ignition) board is still clicking but it's not sending a spark down to the igniter so you need to replace the board.
Problem: It's clogged with food debris
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.
A gas oven igniter works by sparking and heating the gas emitted from the oven, so without it, the oven will not be able to produce heat. However, as so much rests on this little igniter, they are prone to a bit of wear and tear.
Locate the igniter near the oven burner at the back of the oven. Use a soft brush or a can of compressed air to gently remove any food particles, or grease from the igniter. Be careful not to apply excessive force to avoid damaging the igniter. Do not use water or any liquid cleaner on the igniter.
Clean any food debris out of the burner with a toothpick or compressed air. While you're at it, clean the grate, cap, and case. Check the wires connecting the igniter to the control module. If there's a loose connection, tighten it.
Answer: If sparks are visible inside the oven, immediately discontinue use and shut the unit off at the circuit breaker.
Several common ignition system problems can cause your vehicle to fail to start or run poorly. One of the most common is a dead battery. If your battery dies, your vehicle won't have enough power to start. Other common problems include a faulty starter, a bad ignition switch, a faulty distributor, and worn spark plugs.
The most likely reason why a stove no longer makes a clicking noise is due to a faulty spark module. Like most types of electric components, spark modules can burn out and stop working over time.
Soak a cotton swab in alcohol and clean the white porcelain igniter thoroughly. Also clean the metal burner cap with a cotton swab. Try the burner again. If you still hear clicking but don't see a spark then it's time to try option three, thorough cleaning of the metal burner head parts.
