Gas Cooktop Electronic Igniters: How They Work and How to Replace

Introduction

Gas cooktop’s electronic igniter is an important component that helps ignite the fire in your gas stove burner. When you turn the stove’s control knob, the igniter creates a spark that combines with the gas to ignite the fire. But how does this igniter work? When should it be replaced? And how to replace it yourself? Read our complete guide to find answers to all these questions.

How do electronic igniters work?

Gas cooktop’s electronic igniter is basically an electric spark generator. It works by following these steps:

1. Electric Current

When you turn the burner knob, current flows to the electrodes inside the igniter. This current is usually between 3V and 6V, which is supplied by a battery or transformer.

2. Spark Generation

When the electric current reaches the electrode of the igniter, it creates a high voltage spark. This spark usually occurs several times per second and it combines with the gas to ignite the fire.

3. Gas Flow Control

Gas starts to flow to the gas stove burner when you turn the knob. As the spark from the igniter is generated, the gas mixes with the flame and ignites. If there is no spark, the gas flow is stopped to prevent gas leakage.

4. Safety mechanism

Most igniter systems have a safety device that keeps the gas flow going for a certain amount of time after the spark is generated. If there is no spark, the gas flow is stopped and the hazard is avoided.

When does the igniter need to be replaced?

The following are some common signs that the igniter may need to be replaced:

• No spark: If you do not see a spark after turning the burner knob, the igniter may be bad.
• Weak spark: If the spark is weak or sparks intermittently, the igniter needs to be replaced.
• Chipped or Damaged Igniter: If the igniter wire or electrode is damaged, it should be replaced.
• Burner not igniting: If gas flow to the burner is OK but not igniting, the igniter may be bad.
• Black spots on burner: If black spots appear around the burner, the igniter may have overheated and may need to be replaced.

Tools Required to Replace Igniter

Gather the following tools before replacing the igniter:

• New igniter (according to your stove model)
• Screwdriver (usually Phillips or flathead)
• Pliers or tweezers (for holding wire)
• Multimeter (for checking current flow)
• Gloves (for safety)

Step by Step Igniter Replacement Procedure

Step 1: Disconnect the power supply

Disconnect the power supply to the stove first. To do this, unplug the stove’s power cable or turn off the power supply at the circuit breaker.

Step 2: Remove the burner cover

Remove the burner cover. On most stoves the burner cover comes off easily, but some models may have screws attached. Unscrew the screws and remove the cover.

Step 3: Remove the old igniter

Find the old igniter. It is usually mounted next to or below the burner. Carefully remove the igniter wire. Use pliers or tweezers when opening the wire to avoid damaging the wire.

Step 4: Install the new igniter

Put the new igniter in place of the old one. Connect the igniter wire properly. Check if the cable is well connected.

Step 5: Reinstall the burner cover

Reattach the burner cover and tighten the screws.

Step 6: Restart the power supply

Restart the power supply to the stove. Check that the new igniter is working. Turn the burner knob to see if sparks are produced.

Caution When Replacing Igniter

Observe the following precautions when replacing the igniter:

• Disconnect the power supply: Disconnect the power supply before doing any electrical work.

Conclusion

Gas cooktop’s electronic igniter is an important part that makes your cooking experience easier and safer. When the igniter stops working, repeated attempts are made to ignite the burner, which can become time-consuming. Sometimes the igniter does not work properly due to poor spark or dirt. If such a problem occurs, the igniter should be replaced quickly, as long-term use of a bad igniter can damage the burner or risk gas leakage.

You can replace the igniter yourself by following the steps above. But if you are not experienced with electronic components or have any doubts, definitely seek the help of a trained technician. It is important to disconnect the power supply and check the model number of the part before attempting it yourself. Installing the wrong model igniter will not work or may damage the entire system.

Igniter Maintenance & Longevity Tips

Some simple maintenance procedures should be followed to keep the igniter usable for a long time. First, regularly clean around the burner and igniter. Oil, food particles or other debris spilled during cooking can accumulate on the spark point of the igniter and disrupt spark generation. Use a dry cloth or brush to clean. Second, check the igniter wires for damage. If the wires are frayed or loose, they need to be replaced. Third, if excess water or liquid falls on the igniter, immediately disconnect the power supply and dry it.

Easy way to clean igniter

• Remove the burner cover: First separate the burner cover to expose the entire igniter.
• Clean dirt: Use a dry toothbrush or small brush to clean dirt from the igniter spark point and wire junction.
• Clean with alcohol (if needed): If dirt is stubborn, wipe lightly with a cloth dampened with ethyl alcohol or isopropyl alcohol. But be careful not to get alcohol on any other part.
• Dry: When completely dry, replace the burner cover and switch on the power supply.

When not to replace the igniter?

Igniter replacement is not the solution to all problems. In some cases the problem may occur even if the igniter is fine. For example:

• Low gas flow to the burner: If the gas flow to the burner is low, the fire will not ignite. In this case, gas line or burner opening should be cleaned.
• Thermocouple problem: Some gas cooktops have a thermocouple in addition to the igniter, which controls the gas flow. If the thermocouple does not work, replacing the igniter will not solve the problem.
• Gas valve problem: If the gas valve is not working properly, replacing the igniter will not help. In this case the gas valve should be replaced.

Things to Check Before Buying Igniter

Different brands and models of igniters are available in the market. A few important points should be considered for selecting the right igniter:

• Check the model number: If you know the model number of your gas cooktop, buy the igniter according to it. Finding the right igniter is easy by searching online stores or local stores by model number.
• Check Compatibility: Not all igniters work with all gas cooktops. So before buying make sure that the igniter is compatible with your cooktop.
• Brand and Quality: Good brand igniters usually last longer. For example, igniters from Bosch, Whirlpool, LG, or Samsung are good quality.
• Price and Warranty: Avoid igniters that are very cheap in terms of price, as they can break quickly. Also should buy igniter with warranty, so that in case of any problem later it can be replaced free of cost.
