Thermal Sensor Error (OC/SC)

What does InFb mean?

A thermal sensor detected error, indicating either an open circuit (OC) or short circuit (SC) in the internal thermal sensor circuit. This prevents the drive from accurately monitoring its internal temperature, risking overheating and damage if left unresolved.

Complete Troubleshooting Guide

1. 1

   Power cycle the drive.

2. 2

   Check for any visible damage to the drive's internal wiring or thermal sensor connections.

3. 3

   Ensure proper cooling airflow to the drive and that cooling fans are operational.

4. 4

   If the fault persists, it indicates a failure of the internal thermal sensor or its associated circuit, requiring repair or replacement.
