Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A refrigerator section without a working temperature sensor cannot maintain food-safe temperatures reliably. Move perishables out and arrange service.
Can I reset the code?
Yes. A breaker reset can clear E01 if it was caused by a transient connection issue. If the sensor or harness has actually failed, E01 returns within minutes.
When to stop immediately?
Stop if you notice: E01 returns immediately after every reset, Refrigerator temperature climbs above 45°F.
Symptoms You May Notice
Refrigerator section runs warmer than the setpoint
Food in the refrigerator compartment feels too warm and the temperature display shows a value well above the set temperature.
Compressor cycles erratically or runs continuously
The compressor either never seems to shut off or starts and stops at the wrong intervals because the control has no reliable temperature reading.
Display shows the actual temperature reading is dashes or zero
When you check the current refrigerator temperature on the user interface, it shows dashes, zero, or an obviously wrong value.
Possible Causes
Failed refrigerator compartment sensor
The temperature sensor inside the refrigerator section has failed open or shorted internally.
Requires ProfessionalDamaged sensor wiring harness
The harness connecting the sensor to the main control board has chafed, become disconnected, or been damaged during recent service.
Requires ProfessionalFailed input circuit on the main control board
The sensor input circuit on the main board has been damaged by a power surge or component failure.
Requires ProfessionalSafe Checks You Can Do
-
1
Move perishable food to a backup unit
Move dairy, meat, and other perishables to a cooler or backup refrigerator while you arrange service. The refrigerator compartment is unreliable until repaired.
Thermador Freedom columns hold cold for several hours after a fault, but plan as if the food is at risk.
-
2
Power cycle at the breaker
Switch the dedicated breaker off for 5 minutes then restore power. A clean reset can clear transient sensor glitches caused by a momentary connection issue.
Thermador Freedom columns boot up within 60 seconds and the display reports any persistent fault almost immediately.
When to Call a Professional
Contact a qualified technician if:
- Sensor reads outside the 6.2k ohm range at room temperature on a multimeter
- Visible damage or melted insulation on the sensor harness
- E01 appears alongside other E0X codes
