I first checked to make sure none of the buttons were stuck per the AppliancePartsPros tips and they were OK. Based on the experience of others and AppliancePartsPros advice I opted to replace the control board. I watched the AppliancePartsPros video on how to do this and it looked pretty easy so I ordered the control board. The repair was easy! The hardest part of the whole job was getting the stupid hot air exhaust plumbing reinstalled because I have a short ridged pipe that exits straight out the back through the wall.
