Siemens Refrigerator Error E08

DIY Fix Power reset and observation

1. Disconnect the refrigerator from mains power for ~5–10 minutes
2. Reconnect and observe whether E08 clears and normal operation resumes
3. Monitor internal temperature and listen for unusual compressor or fan behavior

Technician Only Inspect and test temperature sensors and wiring

1. Disconnect power to the unit
2. Access interior sensors according to service manual
3. Measure NTC sensor resistances at stable temperature to check if values are within expected range
4. Inspect sensor harnesses for damage or shorts
5. Replace faulty sensors and re‑test

Parts needed: Temperature sensors (NTC), Sensor wiring harness

Technician Only Diagnose control board measurement circuitry

1. Use diagnostic tools to confirm sensor readings are correctly received by control board
2. Check for damage to board components handling analog‑to‑digital conversion
3. Repair or replace control board if measurement circuitry is defective

Parts needed: Control board / main PCB
