Ok I got it, If you have already replaced the control and have had the outlet checked I cant see anything else that would cause this problem, the only thing I can think of is that either there is a problem with the power outlet or the new control you got sent was bad.
I would run a extension cord to the unit, see if it works on a different circuit, if that does not help the problem return the part and try another PCB.
