So I had rehearsal last night, it's been quite warm recently with the heatwave and we practice in a 15×15 room .... there's 6 of us.... I kept checking it because I'm poor lol but the fan never came on and when we started packing I thought I'd just treet switch it on again and see if the fan would decide to come on. The damn thing never even started again! Got a gig a week on Sunday and I'm poor folk haha help! What could be the problem?
