no power to display

Hi. Fmrst if you have not tried this yet, unplug the unit for 15 mins to reset it. IF this does not work, then Make sure you have 120V coming into the main control board ( WPW10189966). You issue could be the main board or the User interface board (p# W10131868). I have attached a similar tech sheet but not exact for your unit. Follow the tech sheet for User interface issue. It has some diagnostics you can perform. Also, look at the schematic. You should be able to test for power to the U.I. IF your getting proper power to it and its not working then the U.I is faulty.
