I currently have 2 btc miners one has stopped working, just a solid red light this is the one with the node and the other one is plugged in via usb and is working....I've tried restarting it many times fan comes on for a few seconds then nothing.
they have been running flawless for months and both are in balance hashrate
Have you checked if it's connecting to the pool?
Maybe there's an issue with connectivity and there's no work delivered to the miner.
You would need to give more details for anyone to be able to help.
What's the output of the miner?, is it connected?, mining?, what does the dashboard say, etc.
checked pool and the hashrate is 2.5th so thats only one of the miners was 5th before
