Diagnostics from the Board
Dead Board
If the board is not responding, check for voltage through the L1 fuse. If voltage is present there, check voltage
from the J8 orange wire to board neutral on the J8 white wire.
If there is no voltage check for an open thermostat or fuse, then remove power from the dryer and
disconnect the J8 connector. Check continuity between the J8 and J4 wires.
If continuity, replace the board.
