The CEP365 is a 36-inch glass ceramic electric cooktop from Thermador’s older CEF/CEP/CET family, requiring a 40-amp circuit breaker and a hardwired 240V connection rather than a plug. It offered electronic touch features including Panel Lock, Zone Size selection, SMART Power boost, and a Keep Warm setting – an earlier generation of the touch-control ideas found on Thermador’s current induction and electric lines.
Because this model predates today’s app-connected controls, most service issues come down to either the breaker/power supply, the glass-ceramic surface itself (which can crack from impact or from sugar-based spills left to burn on), or the touch panel that runs the Zone Size and SMART Power functions – not anything resembling a modern induction coil or Wi-Fi module.

Most Common Issues on This Model
If the cooktop won't power on at all, first check the household fuse or breaker - Thermador's own troubleshooting guidance for this family starts there before anything else.
A glass ceramic surface that's cracked or chipped from an impact or a boiled-over sugary spill generally needs the whole cooktop replaced rather than a surface-only fix.
Zone Size or SMART Power functions that stop responding often point to the touch control panel rather than the heating element itself.
