01 /Identify the design before interpreting heat
Use the model manual or product information to distinguish coil, radiant and induction cooking. A smooth glass top alone does not identify the heating method. Record what the selected zone displays and whether the controls acknowledge a power setting. Induction cookware recognition differs from the behavior of a radiant element. Do not touch a surface to decide whether it is heating; residual heat may remain even when an indicator changes. Describe the cooking result and control response instead of treating appearance as a safe temperature test.
Keep one-zone and whole-appliance failures separate
State whether the issue affects one position, several positions or every zone. Include information from normal use without starting additional burners simply to test a theory. If the oven in a range still works, report it, but do not regard that as proof of correct cooktop supply. Note any recent outage or electrical work. A single unresponsive zone and an entirely dark cooktop suggest different diagnostic starting points, but neither identifies a component by itself. The technician needs the pattern before deciding which measurements are appropriate.
Check ordinary settings and cookware context
Consult documented lock and zone-selection instructions. For induction, note whether a familiar suitable pan was in place; for other designs, describe pan size and position without assuming they explain a sudden total heat loss. Do not remove a coil, lift the glass, swap internal connections or bypass a selector to compare zones. Those actions go beyond safe external observation. Mention a setting that works intermittently or a code that appears only on one position, preserving the exact symbol rather than translating it from another brand's error list.
Know when to stop and arrange assessment
Stop using a cooktop with cracked glass, uncontrolled heating, smoke, electrical odor or repeated breaker trips. Do not keep resetting protection to continue cooking. Provide model, design, affected location, command response and onset, along with installation access details. Internal wiring, control and heating checks require qualified service. The written estimate should explain the confirmed repair and any separate supply concern. This California scope is electric equipment; gas burners, gas lines and valves are outside it. Confirm the exact model and accepted work before planning the visit.
