Induction, radiant glass-top, and gas cooktops fail in different ways depending on their technology. We service every common cooktop configuration: induction, radiant ceramic, gas open burner, and the high-end integrated cooktops common in custom kitchens. Each type has its own diagnostic patterns and parts.
How a cooktop works
A cooktop is the upper-only cooking surface — no oven attached. Each burner zone is controlled independently via knobs or a touch panel. Induction cooktops use electromagnetic coils to heat ferrous cookware directly (the cooktop surface itself stays cooler). Radiant cooktops use coiled heating elements under a glass surface. Gas cooktops use standard burner + igniter assemblies.
What we typically fix
- 01
Induction zone not detecting pan
Induction requires ferromagnetic cookware (a magnet sticks to the bottom). If you've recently changed pans, that may be it. If the same pan worked before and now doesn't, the coil under that zone may have failed or its detection sensor has lost calibration.
- 02
Glass surface cracked
Glass cooktops crack from impact, thermal shock (cold liquid on a hot zone), or in rare cases from a pan left empty on high heat. Once cracked, the glass needs full replacement — it's both a safety issue and an electrical risk.
- 03
Touch controls unresponsive
Touch panels fail in two ways: water damage (boil-over from a pan reaching the panel area) or a worn control board. Sometimes a panel becomes unresponsive only in spots — touching button positions where the membrane has worn out doesn't register.
- 04
Gas burner won't sustain flame
Burner lights but extinguishes after releasing the knob. The flame sensor (thermocouple) has failed — its job is to confirm flame and keep the gas valve open. Replacement is routine.
- 05
Overheating shutoff
Modern cooktops have over-temperature sensors that cut power if a zone exceeds safe limits. Triggered usually by an empty pan on high heat or a sensor failure. Sometimes the cooktop just needs to cool and reset; sometimes the sensor itself has failed.
Types of cooktops we service
Different builds fail in different ways. Here's what we see most often across each type.
Induction
Electromagnetic coils heat ferromagnetic cookware directly through a glass surface. Fast, efficient, and the surface stays relatively cool. Requires induction-compatible cookware.
Radiant glass-top (ceramic)
Coiled heating elements under a glass surface. Slower heat-up than induction but works with any cookware. The glass surface gets very hot and stays hot after use.
Gas open-burner
Traditional gas burners with visible flames. Most responsive heat control, works with any cookware. Requires gas connection and gas-licensed installation.
Modular / professional
High-end cooktops where multiple burner modules can be combined (induction zone + gas burners on the same cooktop, etc.). Common brands: Miele, Wolf, Gaggenau. More complex internal wiring.
Signs your cooktop needs repair
- Pan no longer recognized on a zone that previously worked
- Visible crack or chip in the glass surface
- Touch buttons that intermittently don't respond
- Gas burner lights but won't stay lit
- Cooktop displaying an error code
Try these before booking
Quick checks that resolve a meaningful share of cooktop calls without a tech visit.
- 01
Test induction cookware (magnet test)
If a magnet sticks firmly to the bottom of your pan, it's induction-compatible. If it doesn't, induction won't work — the cooktop isn't broken.
- 02
Clean the touch controls
Wipe the touch area dry. Cooked-on residue can interfere with touch sensitivity. For light residue, hot water and a microfiber cloth. For heavy residue, a dedicated ceramic cooktop cleaner.
- 03
Inspect the burner cap (gas)
Lift the burner cap, ensure it's seated properly, and check that the small ports around the rim are clear of food debris. A toothpick clears most clogs.
- 04
Check the breaker (electric)
Glass-top and induction cooktops run on 240V circuits with dual breakers. Sometimes one trips, leaving partial function.

Before our visit
What to do
- Clean off cookware and grease
- Identify the cooktop type (induction, radiant, gas)
- Locate the gas shutoff (if gas) or the breaker panel (if electric)
Finding the model number
Model number is on the underside of the cooktop. Without pulling the unit, check the installation manual or look for a label visible in the cabinet below.
Safety
Cracked glass cooktops are a real shock hazard — water and conductive material can reach the heating elements through the crack. Stop using a cracked cooktop until repair. Gas cooktop work is performed by gas-licensed technicians.

Common questions
Specific to cooktop repair.
Why does my induction zone make a buzzing sound?
Can a cracked glass cooktop be repaired without full replacement?
What cookware works with induction?
Why does my gas burner go out as soon as I release the knob?
Can I clean the cooktop with regular kitchen cleaner?
Do you service Miele, Wolf, Gaggenau induction cooktops?
Why is my radiant cooktop slow to heat?
How long should a cooktop last?
What's the difference between induction and radiant?
Worth knowing
How long cooktops last
10–13 years for mainstream cooktops. Premium induction cooktops (Miele, Wolf, Gaggenau) often last 15+ years. Touch panels and induction coils are the most common parts to fail; glass cracks are environmental rather than wear-based.
What we don't service
We work on residential cooktops. We don't service commercial cooking surfaces.
