New problem today, came in this morning and the gantrywas down in the front, exit light on. put im manual override and returned to home. put $ now and pull on treadle and the gantry moves 5 feet and blowers come on. have tried 3 times, same thing. inside the cabinet on top 0,1,4,5,26,27,10 are lit. on bottom row 26,27 are lit and 16 is flashing? I was told if an eye is bad the gantry will still run you just lose the safety feature....prox on wheel maybe?
