Connections top and bottom ok. recently moved house but used several times since and was ok.
1) Exchange batteries for new ones.
2) Tight the flexible cable from keypanel vs display board.
3) Tight again the connector from display board to lower board or main motor board.4)adjust the sensor reed switch bby 1/8" see the diagram attached.
5)See if you test measure for +5VDC coming from power suply then main motor board and finally Display board.
6) Test the power supply form output +5VDC , and input from main motor controller board.
See the block diagram that I did for people like you, for better and undertanding diagnostic.
suggestion: Run the calibration software read the owner manual and see the steps under your hood. sincerely.Merry Christmas.
