- Check for log events on the FortiGate where the fan is reporting failure. Below is an example screenshot of logs, indicating how frequently they are taken.
- Verify on-site if there is any outage of power. Check if there is any electric burning smell on the FortiGate box. If there is any, take a photograph if possible.
Note:
Do not remove the case housing as it will void the warranty. The following reference image is for example purposes only.
- Verify the lights on the device for Fan failure:
Green: Fan(s) operating normally.
Flashing Green: Fan switching/initialization in progress.
Amber: Fan failure.
Red: Fan error, RPM too low or too high, or both fan sets have at least one alert.
Flashing Red: One fan set has at least one alert.
Off: Fan error or fan is off.
- Collect the following debug logs:
execute sensor list
execute sensor detail
diagnose debug reset
diagnose debug application ipmc -1
diagnose debug console timestamp enable
diagnose debug enable
diagnose debug disable <- To stop debugging.
In the following example from a FortiGate-600F:

Fan1 has issues due to an abnormal RPM.
Note:
Small business to mid-end FortiGate models such as FortiGate-40C through to FortiGate-300C do not have temperature sensors. These commands would not work on this device. After verifying all details, open a TAC ticket to proceed further with an RMA request.
