Red light flashing Antminer S7

[tipaul]

Problem here......When I start the S7 the red light always flashing in front and it cant connect with the pool but I can see the red light open in all hash board and i can feel the heat in the back.Is it the control board problem?

Need a bit more info and maybe a miner GUI screenshot. The light flashingred can mean a number of things that are causing issues. First I would check the fans and make sure they are both working. Then maybe try a factory reset on the controller.

How long are you leaving it for? My S9 on startup will flash the red light for a few mins until its checked everything and its hashing normally.

As said take a screenshot of the GUI. But give it time to start properly first 5-10mins
