A radiant ceramic hob like the KM424 regulates power by switching the element on and off rather than by varying it, which is why a healthy zone on a low setting visibly cycles. When the regulator sticks closed, the zone stays on full regardless of the setting – a problem that is both obvious and genuinely worth acting on quickly, since there is nothing limiting the heat.
Key Features
- Radiant ceramic glass cooktop
- Rotary or touch controls depending on configuration
- Residual heat indicators for each zone
- Hot-plate zones with dual-circuit options
Most Common Issues on This Model
Radiant element open-circuit leaving one zone cold
Energy regulator sticking so a zone stays on full
Ceramic surface cracked by impact or a boil-dry
