Pull the unit from the wall and it`s shell,check the fan to see if it is turning ok by hand,if there is any restriction,it will blow the control board,the circuit board behind the controls,clean the unit while you have it out,if the fan is stiff,and does not turn,this could be the problem,and if so,the circuit board is most likely shot.Also,the circuit board is most likely shot anyway,even if the fan is fine,there is a lot of problems with fedders and other brands,and the circuit boards,they dont last too long.

My unit when you plug it in goes to E. E. how can I correct this problem
