We purchased our home with a Tiger Spa Sumatran hot tub in the backyard. It has (2) 110v and not 220. Power goes to the tub, everything turns on, but the tub won’t heat. I had a hot tub guy come out. He discovered that one of the connections to the mother board isn’t getting power. We have an oxidizer (??) Or something that isn’t necessary so he plugged the pump into that and got it working again. It’s been 24 hrs and the tub isn’t warm at all. Any ideas? New board? Thanks!
