Among the alarm codes an Electrolux refrigerator can print in its numeric display is Er T3. Electrolux says that such a code means the refrigerator needs service, and gives T3 no definition of its own.
Owner checklist
Push each door fully closed.
If you just put in hot food, remember that it can set off the over-temperature alarm.
Avoid leaving a door open for a long time, since that can cause the same alarm.
If the alarm remains
Contact service. The steps are drawn from an Electrolux Australia article that covers T1, T2, T3, T5 and T6 on fridge freezers.
SY CE is a communication error between the UI and the main control board.
