I went down to check my beer earlier and the compressor was on with the temperature at 36 degrees the beer had been fermenting vigorously since Tuesday. The temparture controller was acting funny yesterday showing heating setting instead of cooling,so I unplugged it and plugged it back in and it was acting fine... But just went down a minute ago and it was displaying the heat setting again and the temparture 36 degrees.... How ruined is my beer are all the yeast dead?
