The NotFuzzyWarm suggestion is right the red light signal from your miner might be a signal for high temperature.

To troubleshoot them start from the software before you touch anything on the hardware.
If you can push the fan speed more try that first if not try to flash it you can find firmware from this link https://download.canaan-creative.com/

If it still keeps restarting try to disassemble your unit and clean them. Maybe your miner has full of dirt and dust that is why it's overheating so cleaning them might solve your issue.
