Range Burner Won’t Light? How to Test the Ignitor

 


It's frustrating when a range burner won't light when you are cooking. There are many reasons why a burner may not light, but the most common cause of these failures is the ignitor. The ignitor creates the spark (or heat) to ignite the gas. If the ignitor isn't working correctly, your burner will not light no matter how many times you attempt to ignite it.

This guide will show you how to identify ignitor problems, how to test them safely, and options for cleaning, repairing, or replacing them.

Common Indications of a Bad Ignitor

Before you test the ignitor, it's helpful to recognize the symptoms of a bad ignitor. Here are some common signs:

·         Clicking sound with no flame: The ignitor clicks but won't light the burner.

·         No clicking sound: The ignitor is not sparking.

·         Weak or intermittent spark: The ignitor is too weak to light the gas.

·         Smell of gas without ignition: Gas is flowing, but the ignitor is not doing its job.

If you see any of these signs, it's time to test the ignitor.

Safety First

Working with gas appliances can be very hazardous. Always practice these safety precautions:

·         Always turn off the burner and ensure the appliance is cool.

·         Never forget to unplug the range or turn off the circuit breaker.

·         If you smell a strong gas odor, stop immediately and call a professional.

Step-by-Step Guide: How to Test a Range Burner Ignitor

1. Check Ignitors for Dirt or Damage

In some cases, the only problem is food debris, grease, or moisture on the ignitor. Carefully remove the burner cap and wipe the ignitor tip with a soft brush or cloth. Look for any cracks, chips, or other obvious damage.

2. Inspect for Spark

Reconnect power to the range.

Turn the burner knob to the “light” position.

Watch closely; does the ignitor create a spark? A good ignitor should have a steady clicking sound and produce visible sparks.

If it has no spark, or it is weak, step to the next test.

3. Continuity Test the Ignitor with a Multimeter

If you are comfortable using a few tools, you can test the ignitor for continuity with a multimeter:

Disconnect power and gas again.

Remove the igniter from the mounting.

Set your multimeter to continuity or resistance.

Check Wiring Connections

Loose or corroded wires can be a problem with a faulty ignitor (or igniter). Check wire connections for damage and ensure they are properly attached.

When to Call a Professional

Assuming that the ignitor is not the issue, the issue may be in the spark module, switch, or gas flow. At this time, your best option is to call a certified  range repair technician. Gas appliances can be dangerous to troubleshoot, and you need proper expertise.

A burner that does not light is most often a case of a dirty, damaged, or faulty ignitor. Simply examining the ignitor, cleaning it, and testing it will quickly show whether or not it needs to be replaced or if the issue is elsewhere. Regular maintenance and cleaning can prevent many ignition issues before they become an issue.

An appliance in good working order allows for safe and efficient cooking—no one enjoys having to change their dinner plans because of a stubborn burner.
