Hi, My 30 pint / 24hr Goldstar dehumidifier was working fine. Suddenly it shut off but it had nothing to do with the protection switch. The led indicator is not on. The electricity supply is fine, the knob controlling the dehumidifier level is at max and the fan switch at high. I turn the knob and switch but it still doesn't turn on. Can you help me?
