Cooktop & Rangetop Repair
Cooktops and rangetops sit in the countertop with no oven below, so the whole appliance is the cooking surface and its controls. Induction, gas and electric radiant are three different technologies that share a form factor and almost nothing else.
What the appliance is made of
These are the subsystems a diagnosis works through. Which one is at fault is determined by measurement on site, not by the symptom alone.
Induction
Generator boards under each zone, cooling fans, heat-sink temperature sensors, and a selection module that talks to the power boards over a bus. Most induction faults are reported as codes.
Gas
Spark modules, electrodes, valves and thermocouples. Mechanical throughout — no display, no codes.
Electric radiant
Surface elements, infinite switches or touch control, limiter thermostat.
Downdraft and integrated ventilation
Blower, damper and control module share the cooktop chassis on models like the Miele KMDA series.

Worth knowing
Lifting a glass or ceramic cooktop carries an inherent risk of breakage even with correct technique. We note pre-existing chips and scratches before starting.
Before you call
Have the model and serial number from the rating plate ready, and note when the problem started, whether it is constant or intermittent, and any code on the display. That determines which parts are carried to the visit. Appointments run in a two-hour arrival window and an adult 18 or older needs to be present for the full window.
