Fan not turning on.Resolution
Check the "drive thermo state" in (Drive) Monitoring menu 1.2.
The fans run when the run command is given or when the drive thermal is greater than or equal to 70%,
and turns off when the drive thermal is less than 60%, and runs for 10 minutes after the run command is removed.
For more detailed troubleshooting.
Check the 3 fuses on the fan control board.
Check the X1 terminal to see if you have input voltage coming in.
Check to see if the X1 and X4 plugs have been crossed. Swap X1 and X4 if needed.
