Bertazzoni Induction Cooktop Not Heating — Causes

When a Bertazzoni induction zone will not heat, the very first thing to rule out is the cookware, not the cooktop. Induction only heats ferromagnetic pans, so before you suspect the power module or the zone sensor, put a magnet to the pan base — if it does not stick firmly, that is your answer. If the cookware is right, the failure is usually the zone's power module, its sensor, or the control board.

How Induction Heats — and Why It Sometimes Doesn't#

Each zone's coil generates a high-frequency magnetic field (20-100kHz) that induces eddy currents directly in an iron-bearing pan, so the heat forms in the cookware itself. That is why a non-magnetic pan simply will not heat, and why a zone sensor that cannot detect a valid pan leaves the coil switched off. This symptom is reported across models such as the P365IX, PM360IGX, and P365ICT.

Likely Causes, Ranked#

1. Incompatible cookware#

Induction needs a pan with iron in its base — aluminum, copper, glass, and non-magnetic stainless will not couple to the field. Test with a fridge magnet: a firm stick means it is induction-ready. Clad pans (stainless outside, aluminum core) only work if the base layer is magnetic stainless, small pans below the zone's minimum diameter may go undetected, and a warped base reduces contact enough to stop detection. No repair needed — just the right cookware.

2. Induction power module — IGBT (most likely fault)#

Each zone is driven by a power transistor module (IGBT) that switches the coil. When that module or the coil fails, the zone goes dead even with a proper pan, and an IGBT failure often throws an error code. A healthy coil measures less than 1 ohm, so a technician checks the coil resistance and the module together — both are proprietary parts ordered by model.

3. Zone sensor malfunction#

The zone sensor is a coil array under the glass that detects whether valid cookware is present and how big it is, and it only lets the power module fire when it sees a good pan. A failed sensor gives no heat with compatible cookware, or drops detection partway through cooking. Confirm by setting a known-good ferromagnetic pan on the zone — no detection means the sensor coil or its board connection has failed, and replacing it means lifting the glass top.

4. Glass surface damage#

A crack over a zone can disturb the field and leave that zone cold even when the electronics are fine. Because a compromised glass top is also a safety and moisture-ingress risk, a cracked surface is replaced rather than worked around.

5. Control board overheating#

Blocked ventilation clearance lets the main control board overheat, which shows up as unresponsive controls, erratic behavior, or codes that return right after a power cycle. Confirm the installation has its required clearance, power-cycle at the breaker for ten minutes, and if the fault comes straight back the board has a hardware failure.

A Safety and Sourcing Note#

Bertazzoni appliances often contain high-voltage components or gas connections. Do not attempt repairs beyond basic inspection unless you have professional training. Bertazzoni induction is Italian-made, so power modules and boards can take 2-4 weeks for US delivery and the service network is smaller than the big brands — worth confirming parts and a technician before you commit to a repair.
