GX CS4-I Issue

When I plug in my new CS4-I sometimes nothing happens, the power supply fan doesn’t come on & the compressor doesn’t do anything. If I switch the power supply from 110v to 220v & back to 110v it will then work as normal. Doesn’t happen every time but has happened several times since I got it about 2 weeks ago. im thinking that it’s a power supply issue. I am in contact with GXpump about the problem. Anyone else had this issue with theirs?
