Bosch Refrigerator Error Code E01
Refrigerator compartment temperature sensor fault
The control board is getting an open, shorted, or implausible reading from the fresh-food compartment temperature sensor. Without it, the control can't regulate fridge temperature accurately — expect the compartment to drift warm or cold. The sensor itself or its connector is almost always the cause.
