Induction cooktops require power electronics expertise — not just standard appliance knowledge. Each cooking zone uses an IGBT (Insulated Gate Bipolar Transistor) and induction coil to generate the electromagnetic field that heats cookware. When a zone fails, the diagnosis requires understanding whether the IGBT itself failed, the control board's zone driver failed, or the coil has an open circuit. Most appliance technicians don't work on induction cooktops. Our technicians are trained specifically on induction power electronics.
In Los Angeles, many induction cooktop E-errors and shutoff complaints are actually ventilation-related — the unit overheats from insufficient clearance in the cabinet below. This is especially common after kitchen renovations in Brentwood, West Hollywood, and Silver Lake that reduced undercabinet clearance. We check ventilation before diagnosing electronics on every induction call.
