Induction Cooktop: How It Works, Common Issues That We Fix

Induction cooktops represent the most technologically advanced form of domestic cooking available today. They heat faster than gas, use less energy than conventional electric hobs, and keep the surface itself cool to the touch. As induction becomes increasingly popular across Nairobi homes and professional kitchens, the need for skilled induction cooktop repair has grown — and Cooker Repair is ready to meet it.

How an Induction Cooktop Works

Induction cooking uses electromagnetic energy to heat cookware directly, rather than heating a surface that then heats the pot. This fundamental difference is what makes induction so efficient and fast.

Here is the step-by-step process:

  1. An induction coil sits beneath each cooking zone, embedded under the glass-ceramic surface. This coil is made of tightly wound copper wire.
  2. An inverter board drives alternating current through the coil at high frequency — typically between 20,000 and 100,000 Hz.
  3. The rapidly alternating magnetic field generated by the coil penetrates the glass surface and induces eddy currents in any ferromagnetic cookware (cast iron, magnetic stainless steel) placed above it.
  4. The eddy currents cause the cookware itself to heat due to its own electrical resistance — the pot becomes the heating element. No energy is wasted heating a burner or glass surface.
  5. A pot detection sensor checks for compatible cookware before activating. Place a non-magnetic pan on an induction hob and nothing will happen.
  6. A control board manages power levels, temperature settings, timers, and safety lockouts. Touch controls on the glass surface communicate with the board.
  7. Cooling fans run beneath the cooktop to protect the electronics from the residual heat conducted from the cookware.

Induction Requires Specialist Repair

The inverter boards and control electronics inside induction cooktops are sophisticated components that require proper diagnostic equipment and component-level repair skills. Attempting amateur repair on an induction cooktop risks further board damage and electric shock. Trust your induction cooktop to our trained technicians.
