A gas oven that won’t light can turn cooking into a frustrating experience, especially when you’re preparing a meal for your family or hosting guests.
Fortunately, most gas oven issues can be diagnosed and resolved with a bit of troubleshooting. In this guide, we’ll walk you through the most common reasons your gas oven isn’t lighting and provide a detailed, step-by-step approach to identifying and fixing the problem.
Common Reasons Why a Gas Oven Won’t Light
Before diving into the troubleshooting steps, it’s essential to understand the potential culprits. Some of the most common causes include:
- Faulty Igniter
- Clogged Burner Ports
- Gas Supply Issues
- Defective Safety Valve
- Thermostat Malfunction
- Control Board Problems
Understanding these components can help you narrow down the issue more effectively.
Step-by-Step Troubleshooting Guide
1. Ensure Safety First
Before beginning any inspection or repair, take proper safety precautions:
- Unplug the oven or turn off the circuit breaker.
- Shut off the gas supply to avoid leaks.
- Wear protective gloves and ensure the area is well-ventilated.
Tip: If you smell gas, evacuate the area immediately and contact your gas provider or emergency services.
2. Check If the Oven Is Getting Power
Although it’s a gas oven, it still requires electricity to power the igniter and control panel.
- Make sure the appliance is plugged in.
- Check the circuit breaker to see if it has tripped.
If the control panel doesn’t light up or respond, you may be dealing with an electrical issue.
3. Inspect the Igniter
The igniter is one of the most common reasons your gas oven won’t light.
- Remove the oven’s bottom panel to locate the igniter.
- Turn the oven on and watch if the igniter glows.
- If it glows but the oven doesn’t light, it may not be getting hot enough to open the gas valve.
Solution: Replace the igniter if it’s not glowing at all or if it glows weakly.
4. Examine the Bake Burner
Clogged burner holes can prevent gas from flowing correctly.
- Remove debris or food particles from the burner using a soft brush.
- Check for signs of corrosion or damage.
Clean the burner thoroughly and test the oven again.
5. Verify the Gas Supply
Ensure your gas supply is working properly:
- Confirm that the gas shut-off valve is open.
- Check if other gas appliances (like a stovetop) are working.
- If you’re using propane, ensure the tank isn’t empty.
6. Test the Safety Valve
The safety valve works with the igniter to control gas flow. If either fails, the oven won’t light.
- Use a multimeter to test for continuity.
- No continuity? The safety valve needs replacing.
This component may require a professional repair if you’re unfamiliar with electrical testing.
7. Inspect the Thermostat
A faulty oven thermostat can prevent the oven from reaching the temperature needed to ignite.
- Use an oven thermometer to check if the internal temperature matches the control setting.
- A discrepancy may indicate a defective thermostat.

8. Look at the Control Board
Newer gas ovens rely on electronic control boards to manage oven functions.
- If you’ve ruled out other causes, the control board may be at fault.
- Signs of damage include burnt spots or non-responsive controls.
Consider calling a technician to test and replace the board if needed.
When to Call a Professional
If you’ve walked through all these steps and your oven still won’t light, it may be time to call a professional technician. Issues with gas lines, internal wiring, or control boards can be complex and hazardous.
We recommend certified repair professionals for:
- Gas leaks
- Control board replacements
- Safety valve diagnostics
Preventative Maintenance Tips
To reduce the chances of future issues, keep your gas oven in top condition:
- Clean regularly: Remove food debris from burners and interior surfaces.
- Check igniters: Make it a habit to inspect them for wear.
- Annual inspection: Have a professional examine your appliance once a year.
