I just purchased a new control board from you and installed it. However, when I put the board in and turned the unit back on nothing would show up on the LED screen. There were no "---" or anything so I could not select a model and set up the board. In addition any button I press simply beeps with no response. Please advise. - John

Thanks for responding Gene. Control board is right. There is no lights on any of the selectors. Totally dark. When you push a button it just beeps.

Previously the old board I replaced just froze. I could get it to go into test mode or anything. I check to see if there was power coming into the board at the P1 plug and there was. So that is when I decided to change out the board. The only other thing I did was I clean out the drain filter while I was at it. That's about it. Everything else seems to be ok, but I could never get it to run a test mode. Unless I hear something new, I plan on shipping board back tomorrow and see if that is the problem. Seems strange I would get a bad brand new board, but maybe not. Again thanks for help and let me know if there is something else you can think of I am missing.
