After reading reviews from others with the same problem, I opted to replace the control board. It took a little more than 2 hours to replace the board, mostly due to the extremely small space the control board was housed in (about 7 x 5 inches) and the fact the replacement board was not an exact replacement. For the most part, 80% of the wire connections were in the same locations, some were slightly moved. I'm not an electrician, so I just checked the markings beside the connections and made sure I moved the wire to the new connection with the same marking. I changed each wire one at a time. Put everything back together and it's been working for a week now. A extremely small ratcheting phillips screwdriver would help a lot. The hardest part of the whole job was trying to access the screws holding the board in and then putting them back in with the new board.
