If you have unplugged the unit for a few minuets it should reset the control board. You do have to leave it unplugged for a few minuets for it to reset. Unplugging it and then plugging it right back in isnt sufficient to reset the control board.
If you have done this then the next step is to call for service under the units warrenty. Any further attempts to repair it beyond the basic reset proceedure will void the warrenty.
Please let me know if you require further assistance, or information. If not please click on "ACCEPT".Thank you.
