    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 J8 WHITE wire. If no voltage check for an open thermostat or fuse. Remove power from the dryer and disconnect the J8 connector.
  • Page 41 Moisture Sensor Rods Check from the J25 connector on the board. Look for approximately 5 VDC. Lay a wet cloth across the rods in the drum. You should see the voltage drop. If you do not see the voltage drop, disconnect power from the dryer. Disconnect the J25 connector from the board.
