What E01 means

E01 lights up and the main compartment may wander away from its set temperature. Thermador's owner literature is silent on it, yet several independent repair sources give the same reading: the thermistor (an NTC type) that watches the fresh-food section is outside its range, or the control board simply cannot read it. The code is a diagnostic hint, not a confirmed verdict.

Usual causes of E01

  • An open circuit or short inside the fresh-food thermistor
  • Corrosion or dampness where the sensor plugs in
  • A wiring harness damaged between the sensor and the board
  • A healthy sensor whose board input misreads it
✓ A safe check worth trying

1. Cut power at the breaker for several minutes, then turn it on again. 2. If E01 comes back, place an ordinary thermometer in the fresh-food section. 3. Compare its number with what the display claims. 4. Tell the technician whether cooling looks affected.

! Why you should stop here
  • Checking the sensor requires measuring its resistance at a known temperature behind interior panels, and the board must be cleared before anyone orders parts.
  • Replacing a sensor without proving the board innocent risks paying for the same code twice.
Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

E01E01 questions
Will cooling carry on while E01 is displayed?

Frequently it falls back to a default cycle, but with no valid reading the compartment can drift too warm or too cold, so confirm the temperature yourself with a thermometer.

Is changing the sensor a major job?

The part itself is small and cheap. Most of the labor goes into reaching it and proving the board is not the actual culprit. Ask the technician to test the board too.

Is this meaning official?

No. Thermador's literature does not list the code. The meaning comes from independent repair references that agree with one another. Treat it as strong evidence, not a certainty.
