Gas burner not igniting

Short answer

On a modern gas range, turning the knob to Lite sends a spark from a small ceramic electrode beside the burner while gas flows from the ports around the burner head.

Soon A burner that will not light is usually a dirty or wet burner, not a gas fault, but any smell of gas that does not clear right away is an emergency: leave the building and call the gas utility.

Quick answer

What this symptom usually means

On a modern gas range, turning the knob to Lite sends a spark from a small ceramic electrode beside the burner while gas flows from the ports around the burner head. If the spark is there (you hear clicking) but there is no flame, the gas is usually not reaching the spark: ports blocked with food, a burner cap knocked off centre, a burner head still wet after cleaning, or an electrode that has been pushed out of position. GE and Whirlpool both put those first. Whirlpool adds a control lockout that engages after a power cut on some models, and a downdraft vent blowing the gas away from the spark.

If there is no clicking at all, the spark side is the question: the range may have no power (the burners need electricity to spark even though they burn gas), the spark module may have failed, or the switch behind that knob may be worn. If every burner is out at once, the gas supply may be shut. Any of the gas-side possibilities, from the supply valve to the burner valves and the manifold, are for a licensed gas technician, and are not something to probe at home.

Safety warningStop and call if: Gas smell that persists after the knobs are off; Clicking that continues with the knobs off (spark module or a wet switch; unplug the range or switch the breaker off); Flames that are yellow, lifting, or much larger than normal.
Quick check · safe to try first

Checks you can do yourself

  1. Smell firstIf you smell gas at any point, stop the checks, do not operate any switch, open a window if you are beside one, leave the building, and call your gas utility from outside: in Ottawa, the Enbridge Gas 24-hour emergency line, 1-866-763-5427; in Gatineau, the Enbridge Gaz Québec 24-hour emergency line, 819-771-8321, option 1. Call 911 if anyone feels unwell or the smell is strong. Come back to the checks below only if there is no smell.
  2. Burner cap seatingWith the range off and cool, lift the cap off the affected burner and set it back so it sits flat and centred on the burner head. A cap knocked askew when a pot was moved is a common cause.
  3. Dry and clean the burnerIf the burner was recently cleaned or had a boil-over, lift the cap and head and let them dry fully; a warm (not hot) oven for half an hour works. Clear the small ports around the head with a straight pin or soft brush without enlarging them, and wipe the white ceramic electrode clean and dry. Refit the head and cap properly.
  4. Knob positionTurn to the Lite position and hold briefly; the spark only fires there. A burner may need several seconds and, per GE, up to a dozen clicks after cleaning.
  5. Power and lockoutPlug a lamp into the range's outlet and check the breaker; no power means no spark. If the display says Locked or shows a padlock, hold the lock key for three seconds.
  6. Downdraft or fanIf a downdraft vent or a strong hood fan is running, turn it down and try again; moving air can pull the gas away from the spark.

Nothing above involves gas, wiring, refrigerant or removing panels.

Technician needed

What our technician checks

These need panels off, live electrical tests or a licensed trade, so they are left to the technician:

  • Anything on the gas valves, manifold, orifices, connector or supply line, including tightening fittings
  • Testing or replacing the spark module or electrode wiring
  • Leak testing or adjusting flame size or air shutters
The visit
$129 + tax

Gas appliance diagnostic: $129 + tax (electric models $89 + tax, or $129 + tax for Thermador, Miele, Viking, Wolf and Fisher & Paykel).

Waived when you proceed with the repair. You get the cause, the price and our repair-or-replace verdict in writing before any work.

Common parts involved

Repairs a technician may recommend

After inspection, not from the symptom alone.

Repair

Spark electrode replacement

When the electrode is cracked, will not spark or is out of position and cannot be reseated.

Repair

Spark module replacement

When no burner clicks with power confirmed, or clicking will not stop.

Repair

Burner switch or harness replacement

When one knob does not trigger a spark or triggers it continuously.

Repair

Burner head, cap or orifice cleaning and replacement

When ports are corroded or the head is warped. Gas-carrying parts are handled by licensed gas technicians.

Repair

Burner valve or manifold repair

When gas is not reaching a burner with the ports clear. Done by licensed gas technicians; never a home repair.

Repair

Gas supply and connector check

When all burners are out; licensed gas technicians checks the appliance shut-off and flexible connector, and anything beyond the appliance goes to a licensed gas fitter.

Repair or replace

Cost, and whether to fix it

What the repair costs depends on the part, the labour and whether a second visit is needed for an ordered part; the written finding gives the total before any work. Our guides on what drives repair costs, stove & range repair costs and repair versus replacement explain how to weigh it.

Who to call

RepairWell diagnoses and repairs this in homes and businesses across Ottawa and Gatineau; the diagnostic ($129 + tax for a gas appliance) is waived when you proceed with the repair. If the stove & range is still under the manufacturer's warranty, contact the manufacturer first: warranty repairs usually have to go through their authorized network.

When to book

Book when the burner still will not light after the cap is seated, the burner is dry and clean and the range has power; when no burner clicks; when clicking will not stop; or when flames look wrong. Say which burners are affected and whether you hear the spark. We diagnose and repair gas ranges; gas-side work is done by licensed gas technicians, and anything upstream of the appliance connector goes to a licensed gas fitter. The diagnostic visit is $89 + tax, waived if you proceed. See stove and range repair and, for a separate gas cooktop, cooktop repair.

Questions

Gas burner not igniting: questions

The burner clicks and clicks but never lights. What is that?

The spark is working but gas is not reaching it: usually a wet or dirty burner, a cap off centre, or an electrode out of position. Clean and dry it as described above. If it still fails, the burner valve or orifice may be blocked, which is a technician job.

A burner keeps clicking after I turn it off. Is that dangerous?

It is not a gas hazard on its own, but it means the spark switch or module is wet or failing. Unplug the range or switch off its breaker until it can be looked at.

Can I light the burner with a match while I wait?

Some manuals describe lighting a burner manually during a power cut. Follow yours exactly if it allows it, and never do it if you can smell gas. It is not a substitute for repair.

Who do I call if I smell gas?

Your gas utility, from outside the building: in Ottawa, the Enbridge Gas 24-hour emergency line, 1-866-763-5427; in Gatineau, the Enbridge Gaz Québec 24-hour emergency line, 819-771-8321, option 1. Call 911 if anyone feels unwell or the smell is strong. Not an appliance repair company. We come after the utility has confirmed the supply is safe.
