Frigidare Model Lft7000eso. Original problem would not spin. cleaned pump trap, unit worked for about 2 months. Unit started not to spin again. Put unit in diagnostic mode and unit did spin. Got error code 48. Ordered lock assembly. I used wahser serveral times while waiting for lock. Unit wont do anything now Replaced lock assemby..no change . Unit powers on ,But when pressing start door does not lock and no functions Can not get it to go into diagnostic mode. checked all wiring connecdtors and wiring harness to lock assembly no problem found. Also checked voltage on control board. voltage is normal120Vac in12Volt out.
