Gas Burners
The most common gas cooktop complaint is a burner that sparks but will not light. Clean the cap, clear the port, and dry the igniter, since residue and moisture break the spark path. If a single burner stays dead while the others light, that igniter or its wiring is the likely fault. A burner that lights but burns yellow points to the altitude air-fuel mix rather than a broken part.
Induction Zones
An induction zone works only with magnetic, flat-bottomed cookware, so the first check is the pan; a non-magnetic pot simply will not heat and the zone may flash. If the cookware is correct and the zone still will not respond, or it shows a fault or shuts off under load, the induction element or its control board needs testing. Keep the cooling vents clear, since a hot electronics bay will reduce power to protect itself.
Radiant Glass Elements
Radiant elements cycle on and off to hold a set temperature, which is normal. A zone that never reaches heat, cycles erratically, or stays off usually has a failed element, a worn infinite switch, or a control fault. These need testing to isolate. Cracks or pitting in the glass are a separate concern and should be looked at promptly. All are defined cooktop repairs.
