Let’s get started with understanding how your stove’s ignition is supposed to work…

How Does The Ignition Process On A Gas Stove Work?

The igniter on your gas stove has an important job – generating a spark to ignite the gas and light the burner.

Here is a simplified breakdown of how appliance ignition works:

1. You turn the burner knob to release gas flow
2. Electricity flows to the igniter module
3. The igniter creates a high-voltage spark
4. The spark ignites the gas at the burner ports
5. Gas combustion creates a flame for cooking

This process happens in an instant, with a clearly audible “click” sounding from the igniter right before a flame appears.

The igniter itself is a small ceramic or metal tip connected to wiring that runs to an ignition control module. It is positioned close to the burner to create a spark that can jump to the gaseous fuel source.

Without the igniter sparking properly, gas will not ignite on your stove. The burner may release gas odor, but no flame results. Proper diagnosing and repairing of the igniter is needed to get stovetop burners working again.

Common Causes Of A Stove Igniter Not Sparking

If your gas stove igniter is no longer creating a spark, there are a few common culprits to blame.

The most typical reasons an igniter fails to spark are:

• Faulty or failing igniter module – The igniter itself is malfunctioning or broken after prolonged use. This is common as igniters wear out over time.
• Loose or damaged wiring – Connections between the igniter and module are compromised, preventing electricity from flowing properly.
• Moisture buildup – Cleaning burners can introduce water or cleaning agents into the ignition points, preventing sparking until fully dry.
• Clogged burner ports – Debris, food, grease in the burner can block the igniter spark from reaching the gas source.

Pinpointing the exact cause of your non-sparking igniter is important to get the stove working again.

Next, let’s go through some troubleshooting steps to diagnose the problem.

How To Diagnose The Cause Of A Non-Sparking Igniter?

When your gas stove igniter won’t create a spark, some detective work is needed.

Follow these steps to zero in on the cause:

• Check for igniter clicking – Turn on the burner knob and listen closely for a clicking sound coming from the igniter. No click indicates a connectivity issue.
• Inspect wiring – With the stove powered off, examine all visible wiring between the igniter and nearby components. Look for any loose connections, damaged wires, or corrosion.
• Remove the burner cap – Take off the burner grates and cap to expose the base of the igniter and burner ports. Inspect for debris or signs of moisture.
• Check igniter resistance – Use a multimeter to check the ohm reading across the igniter. Out of range resistance indicates a bad igniter that needs replacement.
• Allow components to dry – If moisture is present after cleaning, allow all components to thoroughly dry for 48-72 hours before testing again.

Going through these troubleshooting steps methodically will reveal most common igniter issues. Safety note – always switch off gas and power to the stove before any hands-on diagnosing or repair.

Fixing A Wet Or Moist Igniter After Cleaning

Finding a wet or damp igniter is a likely culprit for reduced sparking power. Cleaning agents and water can temporarily impair igniter function. Here is how to fix a wet igniter:

• Allow the igniter and burner to dry fully over 2-3 days before attempting use. Remaining moisture prevents proper sparking.
• Use compressed air to blow out any moisture lodged in the burner ports or ignition points. Aim air at any openings surrounding the igniter.
• Gently warm components with a hair dryer to expedite drying time. Take care not to overheat the igniter or wiring.
• Check for igniter operation frequently as components dry. Sparking ability should improve steadily.
• Avoid immersing the igniter tip directly in water when cleaning. Use a damp cloth instead. Check for debris clogging the igniter after washing burner caps and grates.

Allowing adequate drying time is crucial for a water-damaged igniter to regain sparking functionality after cleaning. Be patient and do not attempt to use the stove until the system is completely moisture-free.

When To Replace A Faulty or Damaged Igniter?

If drying out a wet igniter does not restore sparking, or if there are signs of physical igniter damage, replacement may be needed.

Here are indicators that the stove igniter itself is faulty and requires replacement:

• Visible cracks in the ceramic igniter tip. This vulnerable area is prone to damage over years of heating and cooling.
• Weak, infrequent or no sparking at all when the burner knob is turned.
• An ohm reading outside the normal operation range. For most igniters, this range is 40-150 ohms.
• Melting or burn marks on the casing and wiring. Exposure to excessive heat can damage the igniter.
• Loose internal wiring contacts causing connectivity issues.
• Corroded or rusted metal contacts unable to conduct properly.
• Old age. The average lifespan of a gas stove igniter is 3-5 years before replacement is needed.

Igniters are inexpensive and easy to replace, restoring instant sparking operation to your burners.

Next we’ll look at the step-by-step process for DIY igniter replacement.

Step-By-Step Igniter Replacement Instructions

With the right igniter replacement part in hand, follow these instructions to safely swap in a new igniter:
