Induction Cookers: How They Work, Common Issues That We Fix

Induction cookers represent the cutting edge of domestic cooking technology. They are fast, energy-efficient, and remarkably safe — but when they develop faults, those faults can be complex. At Cooker Repair, we have the technical expertise to diagnose and fix induction cooker problems that other repairers turn away.

How an Induction Cooker Works

Induction cooking works on a principle of electromagnetic energy transfer. Beneath each cooking zone sits a copper coil. When you switch on a zone, an alternating electric current passes through this coil, generating a rapidly oscillating magnetic field above the surface.

When you place a ferromagnetic pan — made of iron or certain types of stainless steel — on the zone, this magnetic field induces electrical currents (called eddy currents) directly within the base of the pan itself. These currents create heat inside the pan, not on the hob surface. The glass-ceramic surface stays relatively cool, only warming slightly from contact with the hot cookware.

Because heat is generated in the pan and not on the surface, induction cookers respond to adjustments almost instantaneously. Lower the setting and heat drops within seconds. Remove the pan and heating stops entirely — a major safety advantage.

Key components include: the induction coils beneath each zone, the power control electronics (IGBT transistors), the touch control interface, the cooling fan, the glass-ceramic surface, and the main control board.

Common Induction Cooker Issues We Fix

Problem Likely Cause Our Fix
Zone not detecting pan Faulty coil or control board sensor Coil or board diagnostic and replacement
Error code displayed Electronics fault or overheating protection triggered Fault code diagnosis and component repair
Touch controls unresponsive Faulty touch panel or control board Touch panel or board replacement
Zone works intermittently Failing IGBT transistor or loose connection Transistor replacement or connection repair
Cooker overheating and shutting off Blocked or faulty cooling fan Fan cleaning or replacement
All zones dead after power surge Blown fuse or damaged control board Fuse replacement or board repair
Excessive humming or buzzing Coil issue (some hum at low settings is normal) Coil inspection and replacement
Display not working Faulty display board or ribbon cable Display component replacement
Cooker trips the electricity Short in internal electronics Full electrical inspection and repair
Cracks in glass surface Physical impact damage Glass surface replacement

A Note on Compatible Cookware

Many induction cooker faults reported to us turn out to be incompatible cookware. Induction only works with ferromagnetic pans — if a magnet does not stick to the base of your pot, it will not work on an induction hob. Always verify your cookware before assuming a fault exists.

Why Choose Cooker Repair?

Induction cooker electronics are sophisticated. Our technicians are trained in circuit-level diagnostics, meaning we can often repair boards rather than replace them wholesale — saving you significant cost.
