Troubleshooting a Gas Stove That Won’t Ignite

A gas stove that won’t ignite or takes too long to light can be a hassle and potentially unsafe if gas builds up in the air. Here’s a step-by-step guide to diagnosing and fixing the problem. Most common issues are easy to resolve with a few simple tools and techniques.

Common Issues and Fixes

1. There’s a Spark, But No Gas

If your stove is sparking but not lighting, it’s likely that the gas orifice is clogged. This happens when food or liquid overflows, and the residue blocks the gas flow.

Tools Needed:

• Screwdriver
• Mild detergent or dish soap
• Sponge
• Microfiber towel
• Paperclip, pin, or needle

Steps:

1. Remove the Grate: Lift off the burner grate.
2. Remove Burner Cap: Take off the burner cap, which sits between the burner and the flame.
3. Remove the Burner Head: Unscrew and lift out the burner head.
4. Clean: Use warm water, detergent, and a sponge to clean the burner cap and head. Dry thoroughly with a microfiber towel.
5. Clear the Orifice: Find the gas orifice (a small hole in the bronze fitting under the burner). Use a paperclip, pin, or needle to gently clear any debris blocking the hole.
6. Reassemble: Reassemble the burner and test to see if it ignites.

2. There’s Gas, But No Spark

If you’re getting gas but no spark to ignite it, the issue likely lies with the igniter. The igniter is a small, white cylinder with a metal contact that creates a spark when activated.

Tools Needed:

• Clean cloth
• Rubbing alcohol
• Tape
• Mild detergent or dish soap
• Sponge
• New igniter (if needed)
• Screwdriver

Steps:

1. Check Connections: Ensure the stove is plugged in and the breaker is on. Remove the grates, burner cap, and burner head. Check for any loose or corroded connections between the igniter and the wires. If the igniter looks corroded, it may need to be replaced.
2. Clean the Igniter: Use rubbing alcohol and a clean cloth to wipe the igniter. Reassemble the burner and test.
3. Replace the Igniter: If cleaning doesn’t help, replace the igniter. Unplug the stove and carefully remove the grates, burner cap, and burner head. Detach the wires from the igniter, clean the burner parts, and install the new igniter by securing it with a screw. Reconnect the wires and reassemble the stove.

3. Gas Flow Issue

If the gas valve is open and the burner still won’t light, there could be a blockage in the gas line or the orifice, preventing the gas from flowing properly.

When to Call a Pro:

• If the igniter is clean and new, but the stove still won’t light.
• If the gas flow seems blocked and cleaning the orifice doesn’t help.
• If you suspect a problem with the gas line or other internal components, call a professional. They have the tools and expertise to safely address issues such as faulty wiring or gas line blockages.

When to Call a Professional

• Persistent ignition issues despite cleaning the igniter and orifice.
• Gas line blockage or gas valve issues.
• Electrical issues with the igniter module, wiring harness, or individual igniters.
• Safety Concerns: If you feel unsure or unsafe about the repair, especially involving gas lines, it’s best to consult a professional.

By addressing these common issues, your stove should be back to working properly in no time. For more complex problems, a professional repair is always the safest option.
