Bosch Refrigerator E01 Error: Fridge Temp Sensor Fault
What Does Bosch Refrigerator Error Code E01 Mean? Error code E01 on a Bosch refrigerator indicates the temperature sensor in the refrigerator compartment has failed. This sensor tells the control board the current temperature so it can cycle the compressor on and off appropriately. Common Causes The NTC thermistor sensor has either drifted out of […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. If the fridge is maintaining proper temperature (check with a thermometer), it is safe to continue using temporarily. If food is spoiling, stop using until repaired.
Can I reset the code?
Yes. A power reset may temporarily clear the error, but if the sensor is faulty, E01 will return.
When to stop immediately?
Stop if you notice: Food is spoiling or freezing in the fridge, Compressor runs non-stop and fridge is very cold.
Symptoms You May Notice
Fridge runs constantly without stopping
The compressor never cycles off because it cannot determine when the target temperature is reached.
Food spoils unexpectedly
Perishable items go bad faster than normal, indicating improper temperature maintenance.
Temperature display shows incorrect reading
The displayed temperature does not match the actual temperature inside the fridge.
Possible Causes
Failed thermistor sensor
The NTC thermistor has drifted out of calibration or developed an open/short circuit.
Requires ProfessionalDamaged sensor wiring
The wire harness connecting the sensor to the main board is damaged or disconnected.
Requires ProfessionalSafe Checks You Can Do
-
1
Check actual temperature
Place a glass of water with a thermometer in the fridge for 2 hours and compare to the display reading.
A fridge should maintain 35-38°F (2-3°C). If the thermometer reads normal but the display is wrong, the sensor is likely faulty.
Tools required -

Power cycle the refrigerator
Unplug the fridge for 5 minutes then plug back in.
A reset can clear a temporary sensor glitch.
