I think the fault is the main control board. How do I replace this part? Thanks
Answer Hello Jeff,
Unplug the appliance from the power supply and wear protective gloves to prevent getting cut on these razor sharp edges. Take several pictures from different angles to refer to during re-assembly and remove the screws holding this board in position. I always try to position the new part beside the old one and transfer the wires to the new board one at a time but sometimes this is not possible, (thus the pictures). Be sure to keep the screws for the board separate since they can sometimes be smaller. Re-assemble in reverse order.
