Do you have a volt-Ohm meter and know how to use it?

And have you tested the inline fuse within the unit?

I've checked both and both results are good.

Ok and if you follow the lead from the fuse to the control board do you also have voltage to the control board testing the power lead to the chassis ground? looking for 120 volts A/C

Ok if you have 120 volts to the control board then the controls display should be lite up . if it is blank just like it has no voltage to it you have a control board issue it sounds like.

Now was this the exact same issue before you replaced the control board?

Customer: replied 1 year ago.
it was. Could I have gotten a bad board?
Expert:  Whrlp Master Tech replied 1 year ago.

Yes you could have gotten a faulty board .

but lets also test the power lead from the fuse to any white (Neutral wire ) on the control board for the 120 volts also first.
