Quick answer
First determine whether the whole gas cooktop is inactive, one burner fails, there is gas but no spark, or there is a spark but no flame. A control lock, loss of supply, wet or misaligned burner parts, blocked ports, or an ignition fault can produce similar symptoms. Use only the installed model's instructions: check the visible control or lock state, confirm the burner cap is seated and dry, and observe whether an ignition click or spark occurs when the knob is placed in the documented ignition position. Do not adjust a regulator, remove a gas jet, move the appliance to inspect its connector, or keep trying to light a burner that delays, pops, lifts, or smells of gas. If you smell gas, hear escaping gas, see smoke, an abnormal flame, scorch marks, sparks, or a control that will not shut off, leave immediately and contact emergency or gas service from a safe location.
Before you begin
Safety first
- This article covers external observation and only model-approved cool, dry, ordinary-access burner care. A qualified gas or appliance professional must handle connectors, valves, regulators, gas pressure, jets, ignition wiring, switches, controls, and persistent or hazardous faults.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Turn all controls OFF and inspect from a safe position. If there is a gas smell or hissing, an uncontrolled flame, delayed bang, smoke, scorch mark, spark, hot wiring, or a control that will not shut off, leave immediately and contact emergency or gas service from outside; do not move the appliance.
Expected result: Record whether all burners fail or only one, whether the cooktop has power or indicator lights, whether a gas smell is present, and whether the symptom is no click, click with no flame, or flame that will not remain lit.
Next step: If no hazard is present, continue with the control-lock and supply checks. If a hazard is present, keep people away and wait for qualified help.
Stop if: Do not operate switches, relight repeatedly, or touch the appliance after a suspected gas leak, uncontrolled flame, smoke, spark, or damaged electrical connection.
Why this matters
Why: A shared failure points toward supply, lock, or common ignition; one-burner failure points toward local cap, port, or igniter conditions. Any fuel or fire symptom ends ordinary checks.
-
Check 2
Read the exact model manual and inspect the visible control panel for a Cooktop Lock, Control Lock, or locked indication; also confirm from a safe, dry position that the cooktop is connected as installed and that an accessible gas shutoff has not been intentionally closed, without moving the appliance or touching gas tubing.
Expected result: Record whether the lock is active, whether power was recently interrupted, whether all burners fail together, and whether the visible shutoff position and installation match the manual.
Next step: Use only the manual's documented unlock command. If the lock is clear but every burner remains inactive, stop and arrange qualified service rather than opening the supply path.
Stop if: Do not move the cooktop, disconnect tubing, adjust a regulator, purge a gas line, or use an unverified control sequence.
Why this matters
Why: Whirlpool notes that a control-lock state can prevent surface burners from operating and that a shared no-flame condition can involve the gas connection or shutoff. A lock that will not clear or an uncertain supply requires model-specific or gas service.
-
Check 3
If there is no gas smell or other hazard, use the exact manual's normal ignition position and observe from normal standing distance whether the selected burner clicks and produces a spark; keep hands, clothing, and face away from the flame area.
Expected result: Record whether there is no click or spark, a click and spark with no flame, a flame that lights then goes out, or a stable flame that appears only after repeated attempts.
Next step: Turn the control OFF after the single observation. Follow only the model-approved dry-out or burner-care path for a cool, dry appliance; request service for no spark, no flame, delayed ignition, or repeated flame loss.
Stop if: Stop for a delayed pop, gas odour, uncontrolled flame, a flame outside the burner, yellow or lifting flame, smoke, or ignition that continues after OFF.
Why this matters
Why: No click or spark suggests the control, power, igniter, or lock path. A click or spark without flame suggests gas supply, cap, port, moisture, or ignition-position issues. Delayed or unstable flame is a safety and service condition, not a reason to keep trying.
-
Check 4
With every control OFF and the burner completely cool, remove only the cap and head parts the exact manual identifies as user-serviceable; wipe visible spill residue, let parts dry thoroughly, and reinstall the correct cap flush with the base without force.
Expected result: Record whether the burner was wet, dirty, cracked, tilted, on the wrong base, or visibly clear and correctly seated, and whether the fault affects one burner or all burners.
Next step: Make one normal ignition observation after the parts are dry and restored. If the burner still fails or the flame is abnormal, leave it OFF and arrange qualified service.
Stop if: Do not clean a hot or lit burner, enlarge or distort ports, remove jets, swap caps by appearance, or operate without the cap in its intended position.
Why this matters
Why: Whirlpool identifies moisture, cap position, and burner-port condition as causes of poor ignition or popping. A clear, dry, correctly seated burner that still fails shifts the diagnosis toward the igniter, switch, gas path, or control.
-
Check 5
If a burner lights but repeatedly goes out or its igniter keeps clicking, note whether a spill, wind, downdraft, or strong ventilation draft is disturbing the flame; turn the burner OFF if it cannot remain stable and do not change gas pressure or the vent installation.
Expected result: Record whether clicking starts after the flame is blown out, whether a downdraft moves the flame, whether the burner reignites, and whether the flame remains stable when the control is OFF.
Next step: Follow only the exact manual's ventilation and flame guidance. If the flame remains unstable or clicking persists, keep the cooktop unused and arrange qualified service.
Stop if: Do not shield a flame with combustible items, alter the downdraft, adjust pressure, or continue with a burner that lifts, goes out, or smells of gas.
Why this matters
Why: Some flame-sensing cooktops retry ignition after an external draft or spill extinguishes the flame. Persistent clicking or repeated flame loss can still indicate an igniter, sensor, burner, or gas issue.
-
Check 6
After the lock, supply, ignition, and cool burner checks, perform no more than one model-documented retry; record the model, burner, knob position, flame state, and result instead of opening the cooktop or repeating ignition attempts.
Expected result: Record whether the burner lights promptly and holds a stable flame, whether all burners remain inactive, whether the same burner fails, or whether clicking, popping, smoke, odour, or abnormal flame returns.
Next step: Give qualified service the model, fuel type, failure pattern, visual observations, and any code or lock indication; leave the cooktop unused until the cause is addressed.
Stop if: Do not keep relighting, open the control panel, disconnect gas tubing, test energized wiring, or continue after a gas, fire, or electrical symptom.
Why this matters
Why: A single successful retry after drying or cap alignment supports a temporary local condition. A persistent failure or recurring unsafe symptom requires diagnosis of the gas, ignition, sensor, burner, or control system.
Use your observations
Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Safety boundary
What you see
All burners fail to light or respond, with no gas smell, no smoke, and no electrical hazard.
Do this next
Check the exact manual's lock state and visible supply arrangement without moving the cooktop; request qualified gas or appliance service if the shared failure remains.
Why this path and its safety boundary
Why it matters: A control lock, shared electrical ignition, gas shutoff, or installation condition is more likely than one blocked port.
Safety stop: Do not move the appliance, open gas connections, or repeatedly operate controls.
-
PATH 02Safety boundary
What you see
Other burners work, but one burner does not light or has a different sound or flame.
Do this next
Let the cool burner dry and reseat its cap as the manual allows, then make one normal observation; request service if it remains inactive or abnormal.
Why this path and its safety boundary
Why it matters: A local cap, port, moisture, igniter, or burner component is more plausible than a shared supply fault.
Safety stop: Do not enlarge the port, swap parts by appearance, or continue with delayed ignition or an abnormal flame.
-
PATH 03Safety boundary
What you see
A selected burner has no click or visible spark when used in the documented ignition position.
Do this next
Turn the control OFF, check only the model-documented lock and visible supply conditions, and arrange service for persistent no-spark behavior.
Why this path and its safety boundary
Why it matters: The lock, electrical supply, control, igniter, or local ignition path may not be operating.
Safety stop: Do not test live wiring, bridge an ignition switch, or attempt to light gas by an improvised method.
-
PATH 04Safety boundary
What you see
The burner clicks or sparks but no flame appears, or the flame lights only after a delay.
Do this next
Turn the control OFF, allow only the manual-approved cool dry-out or cap check, and request qualified service if the burner does not light promptly.
Why this path and its safety boundary
Why it matters: Gas supply, control position, moisture, cap, port, or ignition alignment may be involved; delayed ignition can allow gas to collect.
Safety stop: Stop immediately for gas smell, a bang, flame outside the burner, or repeated failed ignition; do not keep trying.
-
PATH 05Safety boundary
What you see
The cooktop shows a lock indication or burners remain inactive after a power interruption.
Do this next
Use only the exact manual's unlock command and then make one normal observation; request service if the lock cannot clear.
Why this path and its safety boundary
Why it matters: A model-specific control-lock state can prevent burner operation even when the appliance has power.
Safety stop: Do not apply an unverified key sequence, remove controls, or bypass the lock.
-
PATH 06Safety boundary
What you see
The flame lifts, rolls, repeatedly goes out, lights with a bang, smells of gas, or cannot be shut off normally.
Do this next
Leave the area for a suspected gas leak and contact emergency or gas service from outside; otherwise keep controls OFF and arrange qualified service.
Why this path and its safety boundary
Why it matters: A gas, burner, pressure, valve, ignition, or flame-sensing fault may be present and ordinary checks are no longer safe.
Safety stop: Do not move the cooktop, adjust pressure, disconnect tubing, relight repeatedly, or use electrical equipment near suspected gas.
Helpful context
Understand the symptom
Start with the failure pattern, not the burner part
If every burner is dead, the shared gas supply, control lock, electrical supply, or common ignition system deserves attention. If one burner fails while the others work, a cap, port, igniter, or local burner condition is more likely. A click without a flame is not the same as no click: it separates gas-flow and burner conditions from an ignition or electrical path.
Control lock and supply are model-dependent
Some gas cooktops have a control-lock mode that prevents the surface burners from operating after power is restored or when the lock is enabled. A new installation can also have air in the gas line or an unopened shutoff, but gas-line connection and purge work belong to a qualified gas professional. Use the manual for the exact model and fuel type; do not infer supply or pressure from the knob feel.
Keep burner parts cool, dry, and correctly seated
A spill or cleaning can leave moisture around the burner, igniter, or switches. A cap that is tilted, wrong for the base, or not flush can disturb ignition and flame shape. Turn controls OFF, let parts cool and dry, and clean only with the model-approved method. Do not enlarge ports, remove jets, or operate without the cap in place.
Gas and flame symptoms override troubleshooting
A delayed light, bang, hissing sound, repeated ignition, lifting flame, or gas odour can signal a serious fuel or ignition problem. CPSC says to leave immediately if gas is suspected and not to operate electrical equipment or move the appliance to inspect a connector. The cooktop should remain out of use until qualified gas or appliance service confirms safe operation.
Safety boundary
Stop conditions
- If gas is smelled or heard escaping, leave immediately and contact emergency or gas service from outside; do not operate lights, switches, or other electrical equipment.
- Stop for delayed ignition, a bang, uncontrolled or abnormal flame, smoke, scorch marks, sparks, an arc, or a control that will not shut off.
- Do not move the cooktop to inspect a connector, adjust gas pressure, remove jets or valves, disconnect tubing, or open the control panel.
- Do not enlarge, distort, or aggressively probe burner ports, and do not clean a hot or lit burner; use only the exact manual's cool, dry method.
- Do not keep relighting or operating a burner that fails, clicks with controls OFF, repeatedly goes out, lifts, or remains unstable.
Only after diagnosis
Potential parts
- burner cap or burner head
Consider this category only when the exact model inspection confirms a cracked, warped, incorrect, or damaged cap or head after safe cleaning and alignment checks.
Confirm the exact cooktop model and burner position with the manufacturer or technician; do not swap caps by size or appearance. - electronic igniter or ignition switch
Consider this category only when there is persistent no-spark behavior, clicking with controls OFF, or a service diagnosis of an ignition or switch fault.
Confirm exact model and ignition design with qualified service; electrical and gas-control access is professional work. - flame sensor or gas-control component
Consider this category only when a persistent flame-loss, reignition, or shutoff fault is confirmed by model-specific diagnosis.
Confirm the exact model and approved component with qualified service; do not bypass flame sensing or gas safety controls.
When checks do not resolve it

Common questions
FAQ
Why will none of the burners on my gas cooktop light?
A control lock, shared gas supply, power or ignition system, or recent installation condition may affect every burner. Check the exact manual's lock indication and visible supply arrangement without moving the cooktop. If all burners remain inactive, request qualified gas or appliance service.
Why does one gas burner click but not light?
The burner may be wet, its cap may be tilted or wrong for the base, a port may be obstructed, or gas may not be reaching it. Turn the control OFF, let cool parts dry, and use only the manual-approved cap and port care. Stop for delayed ignition, gas smell, or an abnormal flame.
What if the burner has a spark but no flame?
Check the documented ignition position, moisture, cap alignment, and visible supply conditions only when there is no gas hazard. Turn the control OFF after one observation. If it does not light promptly or gas is smelled, stop trying and arrange qualified gas or appliance service.
Why do all burners click when I use one knob?
Some electronic-ignition designs make all burners click when one control is pushed, while only the selected burner should light. Compare the behavior with the exact manual. Clicking with every control OFF or after a stable flame is a service condition, especially after the area is dry.
Can I fix a gas cooktop that smells like gas or lights with a bang?
No. For a gas smell or suspected leak, leave immediately and contact emergency or gas service from outside without operating electrical equipment or moving the cooktop. A delayed bang, abnormal flame, smoke, spark, or ignition that will not stop requires qualified service before use.
