Answer to continue safely
Is it safe to keep using?
No. A confirmed ignition failure on a gas burner creates a risk of unburned gas accumulation. Do not use the affected burner until the ignition system is inspected and confirmed functional.
Can I reset the code?
Yes. Cleaning the burner and igniter often resolves E1 without a formal reset. If the code persists after cleaning, a power-cycle reset of the rangetop control board followed by professional inspection is recommended.
When to stop immediately?
Stop if you notice: A strong gas smell is present before or during ignition attempts — evacuate and call the gas utility., No spark is visible at the electrode after thorough cleaning..
Symptoms You May Notice
Selected burner does not light despite audible clicking
The electronic igniter fires repeatedly with a clicking sound, but no flame appears at the burner ports, leaving the burner surface cold after the knob is held in the ignite position.
E1 fault code shown on rangetop display
After exhausting the ignition retry limit, the control board displays E1 and may illuminate a fault indicator LED near the affected burner knob.
Mild gas odor detectable near the burner
Small amounts of unburned gas may be released during failed ignition attempts before the control system closes the gas valve and locks out the burner.
Burner cap or electrode appears clogged or damp
Visual inspection reveals food residue packed into the burner port holes, a cracked burner cap, or a wet igniter electrode — all of which can prevent a reliable ignition arc from forming.
Possible Causes
Clogged burner ports or contaminated igniter
Accumulated food debris, boilover residue, or grease inside the burner port holes blocks gas flow, while a coated igniter electrode fails to produce a clean arc to the burner cap.
DIY PossibleIgniter electrode or spark module failure
The high-voltage spark module or the ceramic igniter electrode has failed due to moisture damage or component aging, producing no spark output even when ports are clean.
Requires ProfessionalInsufficient gas pressure or closed supply valve
A partially closed gas shut-off valve or low line pressure prevents adequate gas flow to the burner, making ignition impossible even when sparking is normal.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean burner ports and igniter electrode
Turn off all burners and allow the rangetop to cool completely. Remove the burner cap and grate. Use a straightened paper clip or soft bristle brush to clear each burner port hole. Clean the igniter electrode with a dry cloth, then a slightly damp cloth, and allow to dry fully before testing.
Hold the paper clip perpendicular to the port hole surface to avoid enlarging or damaging the opening.
-
2
Verify gas supply valve position
Locate the dedicated gas shut-off valve for the rangetop, typically behind or below the unit. Confirm the lever handle is aligned parallel to the supply pipe — this indicates fully open. Rotate a quarter-turn if needed.
Test another gas appliance in the home to confirm the main gas supply is active.

3
Test ignition with a long-reach lighter
After cleaning and drying, hold a lit long-reach lighter near the burner port and slowly turn the knob to the low-flame position. If the burner lights by flame but not by igniter, the electrode or spark module needs service.
Perform this test only after confirming no gas odor is present and with adequate kitchen ventilation.
When to Call a Professional
Contact a qualified technician if:
- The igniter produces no visible arc after cleaning and drying the electrode.
- Gas line pressure has been confirmed adequate but the burner still will not ignite.
- The burner head or cap shows heat damage or warping that cannot be corrected by cleaning.
