Induction Cooktop Dead or Showing Error Codes? Control Board 357266088 – Fix It Fast

If your Bosch, Siemens, or Thermador induction cooktop won’t power on, has unresponsive burner zones, or is displaying persistent error codes, the induction control board is the most likely cause. In most BSH-built induction cooktops, the control board manages power delivery to each induction zone, interprets touch input, and communicates fault codes to the display. When it fails, individual zones may stop working, the unit may not power on at all, or error codes may appear that cannot be cleared by resetting. ⚡ Common failure point in Bosch-built induction cooktops. Part 357266088 is the genuine OEM replacement control board that restores full cooktop operation without modification.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Cooktop is receiving correct voltage at the terminal block (240V confirmed)
• ✔ Main fuse or circuit breaker is not tripped
• ✔ Touch panel / user interface has been ruled out as the failure point
• ✔ Individual induction coils and temperature sensors test within spec
• ✔ ONLY problem is no power, unresponsive zones, or persistent error codes after power cycling

⚙️ Installation

Skill Level: MODERATE — 30–60 minutes. Disconnect power at the breaker before servicing — induction cooktops run on 240V. Remove the cooktop from the countertop cutout by unscrewing the mounting clips from below, then carefully lift and flip to access the underside. Photograph all wiring harness and ribbon cable connections before disconnecting. Swap the control board, reconnect all harnesses, reinstall, restore power, and run a full zone test. Caution: Never touch induction coil components while power is connected — capacitors may retain charge after disconnect.
