What does Electrolux Professional EtC mean?

On a SkyLine combi oven, EtC means the cavity safety thermostat (TSC) has tripped because the cooking chamber reached an over-temperature condition. The oven stops to protect itself.

What does Electrolux Professional EtUC mean?

EtUC indicates the SkyLine oven cavity has reached an over-temperature condition and the oven has stopped. Unlike the safety-switch alarm, this one is recoverable: once the cavity cools, a new cooking cycle can be started.

What does Electrolux Professional Etb mean?

Etb means the SkyLine oven's boiler safety thermostat has tripped due to over-temperature in the steam boiler, and boiler cycles stop. The oven cannot produce steam normally; it switches to an alternative device with reduced performance.
