Induction Cooktop Repair
Induction hob and cooktop repair: IGBT transistors, resonance capacitors, coils, E0/E2/E5 error codes. Bosch, Siemens, AEG, Miele.
Induction cooktops fail most often on the power side: an IGBT transistor in one zone burns out after a mains surge or thermal stress, the resonant capacitor alongside it blows, the pan-detection circuit stops seeing cookware, or the touch slider under the glass starts firing ghost presses. Less often the cooling fan seizes and the whole panel shuts down with an error on the first boil.
We work at the component level on Bosch PXX, PXY and PIE; Siemens EH, EX and flexInduction; Electrolux EHI/EIV and AEG MaxiSense/SensePro; Miele KM; plus Samsung, Beko, Gorenje and Whirlpool. A dead zone almost always traces to one specific IGBT module, a resonant cap or a driver on that zone's board — not the whole panel. Swapping that one part runs a fraction of the cost of the full power module.
A few things we do not do: diagnose without opening the panel on the bench, quote over the phone sight-unseen, or replace whole boards when one component is the cause. Cracked ceramic glass we can replace, but on induction panels with integrated touch zones printed on the glass it is often more expensive than on classic ceramic — we tell you the numbers before you decide.
Diagnosis is free, estimate agreed before work, 3-month warranty.

Common problems we fix
- One zone dead — shorted IGBT transistor or open induction coil
- Error codes E0, E2, E5 on the display — power board or temperature sensor fault
- Touch panel reacts erratically or does not respond at all
- "Pot not detected" even with a proper induction pan
- Cooling fan fails to start — thermal protection shuts the cooktop down
- Buzzing, whining or crackling during operation — ageing resonant capacitors
- Cooktop will not power on — supply board or mains filter failure
- Power suddenly drops — IGBT overheating due to dried-out thermal paste

Induction cooktop electronics and component-level IGBT repair
An induction panel generates cooking power through a resonant LC tank circuit in which the IGBT transistor switches DC voltage at roughly 20–50 kHz. When the IGBT starts overheating — most often because the thermal paste between transistor and heatsink has dried out after 5–8 years — it either shorts (the zone stays cold and the board blows a fuse) or starts switching incorrectly, producing an error code and loud crackling. We diagnose the IGBT with an oscilloscope, check the gate driver signal and inspect the resonant capacitors (typically 0.27–0.33 µF at 1200 V), which also age over time and reduce power transfer.
Touch panel faults usually come from moisture getting under the glass — burnt-on steam or spilled liquid seeps through the seal edge and shorts sensor contacts. Depending on the model we rebuild the sensor module, replace the rubber gaskets, or fit a new panel. NTC temperature sensors under each zone start reporting incorrect readings after 7–10 years — the cooktop then derates too early or triggers thermal shutdown. NTC replacement is a relatively cheap job that fully restores functionality.
Induction panel repair economics and when we honestly say "not worth it"
In the mid- and high-end segments induction cooktop repair is almost always economically justified. Bosch Series 6 and 8, Siemens iQ500 and iQ700, the Miele KM series, Electrolux SenseBoil and top-tier AEG retail at 800–1500 euros new, whereas typical component-level work — IGBT swap, coil repair, NTC sensor or touch panel refurbishment — runs three to five times cheaper. These panels are mechanically built for 15+ years of service, and an electronic failure usually does not mean the cooktop as a whole is worn out.
Things get trickier with entry-level panels (Hansa, Candy, some Beko and Whirlpool models) priced around 250–350 euros. If the whole power board has failed and original parts are out of production, the repair can approach the price of a new unit — and we will tell you so rather than take on work you will later regret. If the glass has cracked on top of an electronics fault, we also suggest considering replacement, since an original induction glass with printed touch zones is an expensive part. Our approach since 1993: honest diagnosis before the work, not a maximum invoice after.
