If your induction cooktop has no power at all, the most likely culprits are a blown internal fuse, a failed control board, or a wiring issue between the outlet and the unit. A dead coil is possible but less common when the whole cooktop is dead rather than just one zone.
Start with what you can check without opening anything.
Check the Obvious First
Confirm the outlet is live. Plug in something else to verify. Built-in induction cooktops run on a dedicated 240V circuit. If the breaker has tripped, reset it and try again. If it trips again immediately, stop there. That points to a short inside the unit or a wiring problem.
Also check the control panel for a child lock. Most brands (Bosch, Samsung, GE Profile, Frigidaire, Whirlpool) have a lock mode that disables all input. Usually it’s a long press on a specific button or a dedicated lock icon. Check your manual if you’re not sure which one.
If power is confirmed and there’s no lock active, the problem is inside the cooktop.
What a Tech Looks For
Internal fuse. This is the most common cause of a fully dead induction cooktop. Most units have one or more glass tube fuses on the main board or near the power input. A power surge or hard short can blow it. The fuse itself is cheap; the work is getting to it safely and identifying whether anything else caused it to blow. If a replacement fuse blows immediately, there’s a deeper failure. That’s exactly when people get into trouble chasing a cheap fix that turns into a bigger repair bill.
Control board. The board runs touch inputs, power regulation, and safety cutoffs. When it fails, the cooktop goes completely dead. A tech checks for burnt components, bulging capacitors, and scorch marks, then tests the board’s output before condemning it. Replacement cost varies a lot by brand and model, so get a quote before deciding whether repair makes sense for your unit’s age and value.
One useful data point: if the unit took a power surge and the board is fried, the coils themselves are usually fine. The coil assemblies and the IGBT driver circuit next to each coil are separate from the logic board and tend to survive surges that kill the control electronics.
IGBT or driver board. The IGBT (insulated gate bipolar transistor) drives the coil for each zone. A shorted IGBT can trigger the cooktop’s protection circuit and cause a full shutdown, even though only one zone actually failed. A tech checks each driver circuit individually. This kind of repair requires desoldering or replacing a board, not something to improvise.
Wiring and power supply. Less common, but worth checking: the internal wiring harness can develop a loose connection, especially in units that have been moved. On hardwired 240V installations, a loose terminal at the junction box is also possible. A tech will check continuity through the harness as part of a standard diagnosis.
Why This Isn’t a DIY Job
Induction cooktops store dangerous voltage in capacitors even after you unplug them. A capacitor that hasn’t fully discharged can cause a serious or fatal shock. This isn’t a theoretical risk. Anyone who’s opened one and knows what they’re looking at respects it. Beyond the shock hazard, replacing the wrong fuse rating, mishandling the board connector, or not identifying the root cause means the unit fails again shortly after.
A proper diagnosis tells you exactly which component failed and whether the repair cost makes sense versus replacement.
