Gas, Radiant, and Induction Cooktops
Each type works differently, so the symptoms and the repairs differ.
| Feature | Gas cooktop | Radiant electric cooktop | Induction cooktop |
|---|---|---|---|
| How it heats | Flame from gas burners | Heating elements under glass | Magnetic field heats the pan itself |
| Surface | Grates over burners | Smooth glass-ceramic | Smooth glass-ceramic |
| Ignition | Igniter and spark module | None | None |
| Cookware | Most cookware | Most flat-bottomed cookware | Magnetic cookware only |
| Common issues | Ignition, clicking, port blockage | Zone not heating, limiter, switch | Pan not detected, error codes, fan |
| Safety note | Gas smell: leave the building and call the gas utility | High-voltage work is technician-only | High-voltage work is technician-only |
Gas and 240V work is technician-only. If you are unsure which type you own, check the manual or look for a gas line connection under the counter.
Gas Cooktop: Clicking and No Ignition
This is the most common gas cooktop call.
Possible factors a technician may check:
- ✓A dirty or wet burner port or igniter
- ✓A burner cap that is misaligned
- ✓A weak or failed igniter
- ✓A spark module or switch fault
- ✓A gas supply or valve issue
Safe observations include checking that burner caps are seated correctly and that the burner is clean and dry. Spills and boil-overs often block ignition. Do not tamper with gas fittings.
Continuous clicking, even when a burner is lit, can be related to moisture, a stuck switch, or a spark-module problem. If clicking continues after the burner is lit, turn the control off and let the surface dry. Keep the area ventilated.
Gas Cooktop: Weak, Yellow, or Uneven Flame
A healthy flame is generally steady and bluish. Flame problems may involve:
Blocked ports
Food residue can distort the flame.
Misaligned burner cap
The flame may be uneven.
Low gas supply or a regulator issue
The flame may be weak overall.
Wrong fuel orifice
Conversions between natural gas and propane need correct parts.
A yellow, sooty, or very tall flame deserves attention, since it can mean incomplete combustion. Stop using that burner and call. Do not adjust gas components yourself.
Radiant Electric Zone Not Heating
A radiant zone that does not heat may involve several areas.
The element
under the glass may have failed.
A limiter or thermal protector
may have opened.
The infinite switch or control
may not be sending power.
A wiring or terminal issue
may be involved.
Dual or triple zones
may have a selector that is not working.
If one zone fails and others work, the cause is likely at that zone or its control. If several fail together, a shared power or control issue becomes more likely. Do not remove the cooktop or touch exposed wiring.
Induction Cooktop: Pan Not Detected
Induction cooktops heat the cookware with a magnetic field, so the pan matters.
Possible reasons the cooktop does not heat:
Non-magnetic cookware
Aluminum, copper, and some stainless steel pans will not work.
A pan that is too small
for the zone.
A warped or uneven base
The pan may not make good contact.
A wet or dirty surface
Moisture can confuse sensors.
A control, inverter, or sensor fault
A simple test is to see whether a magnet sticks firmly to the bottom of the pan. If it does, the pan is likely compatible. If a known-good pan is also not detected, a technician may need to look at the induction hardware.
Induction Noises and Cooling Fans
Induction cooktops can make normal sounds, including a hum, buzz, or fan noise.
Fan noise
is common because the electronics need cooling. It may continue after the zones turn off.
Humming or buzzing
can vary with power level and cookware.
Clicking
can occur as power cycles on and off at lower settings.
Loud grinding or rattling
from the fan may need attention.
A noise worth reporting is a new, louder, or constant one, or one that comes with an error code or failure to heat.
Touch Controls and Display Problems
Many cooktops use touch controls.
Common concerns:
- ✓Unresponsive or erratic touch
- ✓Beeping with an error code
- ✓A control lock that will not release
- ✓Controls that turn on by themselves
- ✓A display that flickers or is dim
Moisture, spills, or grease on the control area can interfere with touch sensing. Wipe the surface gently with a soft cloth. If the controls remain unresponsive after drying and cleaning, a control board or touch panel may need attention. Do not use sharp tools on the controls.
Knobs, Switches, and Modules
Gas cooktops and some electric ones use knobs and switches.
- ✓A knob that spins freely may have a worn stem.
- ✓A knob that is stiff may be dirty or damaged.
- ✓A switch that does not click may have failed.
- ✓A spark module that clicks constantly can be a switch or moisture problem.
Do not force a stuck knob. If a knob will not turn to off, stop using the burner and shut off the power or gas supply if you can do so safely.
Cracked or Chipped Glass
- ✓A heavy impact
- ✓A dropped pan
- ✓Thermal shock from a cold item on a hot surface
- ✓A pan with a rough base that has scratched the glass
- ✓A manufacturing defect
Safety
Glass-ceramic surfaces are strong but can crack.
Possible causes include:
A cracked cooktop is a safety concern. Liquid can reach electrical parts, and the crack can spread. Stop using it, unplug it or turn off power at the breaker if you can do so safely, and call. A small scratch is not a crack, but deep chips need to be checked.
A Burner or Zone Stays On
A Burner or Zone Stays On
An uncontrolled burner is a safety concern.
Possible factors:
- ✓A stuck switch or relay
- ✓A failed touch control
- ✓A gas valve that does not close fully
- ✓A wiring or short problem
Turn the control to off. If the burner or zone does not stop, shut off the breaker for an electric cooktop if it is safe, or close the gas valve for a gas cooktop if you know where it is and can reach it safely. Then call for help. Do not keep using it.
Cookware Compatibility
Cookware affects performance on every cooktop type.
| Cooktop type | Cookware notes |
|---|---|
| Gas | Most cookware works. Match pan size to burner and avoid oversized pans that block ventilation. |
| Radiant electric | Use flat-bottomed pans that sit fully on the glass. Avoid rough bases. |
| Induction | Use magnetic cookware. Test with a magnet. Match pan size to the zone. |
Warped pans, rough bases, and oversized cookware are common sources of poor heating. If a burner or zone works with one pan but not another, the cookware may be the issue.
Error Codes
Modern cooktops display codes to indicate faults. Codes differ by brand and model.
Write down or photograph the code.
Check the owner’s manual.
Note when it appears: at power-up, when a pan is placed, or during cooking.
Mention the code when you call.
A code is a clue, not a diagnosis. A technician may use it together with tests to find the real cause.
Components a Technician May Inspect
Depending on your symptoms, a technician may look at:
- ✓Igniters, spark module, and burner assemblies (gas)
- ✓Radiant elements, limiters, and switches (radiant electric)
- ✓Induction coils, inverters, and cooling fans (induction)
- ✓Touch control panel or main control board
- ✓Knobs, valve stems, and infinite switches
- ✓Wiring, terminals, and connectors
- ✓Glass-ceramic surface condition
- ✓Gas valve and supply connection
Naming a burner, element, or sensor is not a diagnosis. A cooktop zone that will not heat can involve the element, a switch, a control, or cookware recognition on induction, and testing decides.
What a Technician Typically Does During a Visit
A typical cooktop diagnosis follows this logic.
Listen to the symptom history and any error codes.
Identify the model, serial number, and type.
Check the power or gas supply connection, using technician-only methods.
Observe the cooktop behavior, such as burner ignition or zone heating.
Test components and controls.
Explain findings and discuss repair options.
Because cooktops are built in, a technician may need access from above or below the counter.
Safe Customer Checks vs Technician-Only Work
Safe for you
- ✓Confirm the breaker and that the cooktop has power
- ✓Make sure burner caps are seated and clean
- ✓Check that no control lock is active
- ✓Wipe the surface and controls with a soft cloth
- ✓Test induction cookware with a magnet
- ✓Try a different pan
- ✓Photograph the label, the surface, and any error code
Technician-only work
- ✓Anything involving gas lines, valves, or fittings
- ✓Live electrical testing
- ✓Replacing igniters, elements, coils, or controls
- ✓Removing the cooktop from the counter
- ✓Opening the cooktop underside
- ✓Bypassing safety devices
Las Cruces Considerations
Cooktops see the heaviest use around gatherings and holidays, when a failure is most noticeable. Heavy use is not a diagnosis, but it is worth mentioning how often the cooktop is used.
Dust and grease can affect burners and controls, and boil-overs can block gas ports. Hard water is a local factor worth knowing about, but it does not apply to most cooktop faults. White film around a burner is usually spilled food or cleaner residue, not a sign of hard water.
Repair or Replace Your Cooktop?
A cooktop repair decision usually weighs several factors.
| Factor | Question |
|---|---|
| Age | How old is it, and is it otherwise sound? |
| Diagnosed failure | Is it an igniter or switch, or a cracked glass or major electronics failure? |
| Parts availability | Can parts be sourced for this model? |
| Repeat failures | Has it been repaired recently? |
| Condition | Is the surface and finish in good shape? |
| Warranty | Does any coverage apply? |
| Replacement cost | Include the countertop cutout, gas or electrical work, and installation |
| Repair quote | Compare it with the installed replacement cost |
Replacing a built-in cooktop can be more involved than replacing a range because of the countertop cutout. A new cooktop may not fit an existing cutout. The “50% rule” sometimes quoted is only a rule of thumb. See the repair or replace guide.
Brand and Model Notes
Gas, radiant electric, and induction cooktops use different parts, and brands differ in control layout. The model plate, usually underneath the unit, identifies the exact model.
Brand names are covered on the brands we repair page. If your appliance is still under warranty, check the warranty terms first, because some warranty repairs must go through the manufacturer or warranty provider.
Cleaning and Care That Supports Cooktop Performance
Keeping the surface clean helps cooktops work reliably. Follow your manual for your model.
Gas burners
keep ports clear of spills. Clean caps and grates as the manual describes, and let parts dry before relighting.
Glass surfaces
use cleaners the manufacturer recommends, and avoid abrasives that can scratch.
Burned-on spills
use a non-scratch scraper if the manual allows.
Controls
wipe with a damp cloth, and do not spray cleaner directly onto touch panels.
Sugar spills on glass
these can pit the surface if left to cool, so check the manual for what to do.
Cookware bases
keep them clean and dry to avoid transferring residue.
Cleaning may solve some ignition and touch-control complaints, but it cannot repair failed parts.

How Urgent Is Your Cooktop Problem?
| What you notice | General urgency | What to do first |
|---|---|---|
| Gas smell | Safety emergency | Do not operate switches or appliances. Leave the building and call the gas utility or emergency services from a safe location |
| Smoke, sparking, or burning smell | High | Stop use; turn off power at the breaker if safe |
| Cracked glass | High | Stop use and keep liquids away from the surface |
| Burner or zone will not shut off | High | Turn it off; shut off the gas or power if safe |
| Burner will not light or zone will not heat | Moderate | Stop using that burner; book a visit |
| Touch controls unresponsive | Lower | Wipe and dry the surface; book if it persists |
After the Visit: What a Repair Should Leave You With
A repair is complete when the cooktop works and the cause is understood. Good practice usually includes:
- ✓Testing each affected burner or zone after repair.
- ✓Checking that gas and power connections are secure and that the cooktop sits properly in the cutout.
- ✓Confirming touch controls and any lock features behave normally.
- ✓Explaining what was found and what was replaced.
- ✓Telling you what to watch for in the coming days, such as ignition behavior or recurring codes.
If the same symptom returns, contact the company promptly rather than waiting.
Things to Avoid While Waiting for Service
Things to Avoid While Waiting for Service
- ✓Do not keep using a burner that clicks continuously or smells of gas.
- ✓Do not use a cracked cooktop.
- ✓Do not pour water on a hot glass surface.
- ✓Do not remove the cooktop from the counter or open the underside.
- ✓Do not use sharp tools or abrasives on touch controls.
- ✓Do not light a gas burner with a match if you smell gas.
- ✓Do not use an extension cord or adapter on an electric cooktop connection.
If a burner or zone cannot be turned off, treat it as urgent and follow the safety steps above.
Separate Installation Considerations
A cooktop sits in a countertop cutout with a cabinet or drawer below, which makes it different from a range in several ways.
| Topic | Why it matters |
|---|---|
| Cutout size | A replacement must fit the existing opening, or the counter may need changes |
| Clearance below | Space under the cooktop affects access and heat considerations |
| Power or gas supply | Gas cooktops need a gas connection; electric and induction units need the right circuit |
| Controls | Controls may be on the surface, on the front edge of the counter, or on a nearby panel |
| Ventilation | A hood or downdraft nearby affects how the cooktop is used |
| Access for service | The unit may need to be lifted out from above or reached from below |
Tell the technician if the cooktop is paired with a wall oven. The two are separate appliances with separate models and parts.
Gas, Radiant, and Induction: A Quick Failure Map
| Type | A zone that will not heat may involve | Safety note |
|---|---|---|
| Gas | Igniter, spark switch, burner ports, gas supply | Gas smell means leave the building and call the gas utility |
| Radiant electric | Element, hot-surface control, wiring, sensor | Cracked glass should not be used |
| Induction | Pan detection, power module, sensor, cooling fan | Cookware must be compatible and flat |
Many induction faults turn out to be cookware compatibility. Try a magnetic, flat-bottomed pan before concluding the cooktop has failed. If it still does not respond, mention the pan test when you call.
Frequently Asked Questions
Why is my gas cooktop clicking but not lighting?
Dirty ports, a misaligned cap, a weak igniter, or a spark-module issue may be involved. A technician needs to test to confirm.
Why won’t my induction cooktop heat?
Cookware that is not magnetic, or a pan that is too small or warped, are common reasons. If a known-good pan fails too, a technician can check the hardware.
Why is one zone on my electric cooktop not working?
The element, a limiter, a switch, or the control may be involved.
Is a cracked cooktop safe to use?
No. Stop using it, since liquid can reach electrical parts and the crack can spread.
Why are my cooktop touch controls not responding?
Moisture, spills, a control lock, or a failing control panel may be involved.
Do you repair cooktops that are part of a range?
Those are covered by Stove Repair.
Do you repair the hood above my cooktop?
See Range Hood Repair.
Should I repair or replace an old cooktop?
It depends on age, diagnosed fault, parts, repeat failures, and replacement cost, including the countertop cutout.
