Hi this is my first post..i am new to learning everything electronics.. so I am stationary engineer and I had two auto sensing hand dryers fail on me. One would just keep running and the other would not run at all. I replaced both with a new board from other units and now they work.. but the robbed units still need fixing .. so something on the board is broke.. looking at both of them there is a lot of oxidation on the same ic chip..on the robbed boards it's very clean..do you think unsoldering and cleaning up the legs that have Oxidation might be a chance it can fix it or should I just order a new parts .. sorry if my terminology is way off, I am very new but thanks for any input .. in the picture it's the ic chip on the right I think is the problem
