wires/connects correctly. If the main power switch cannot turn on after
removing the heater control board especially, make sure to connect the
cable to CN1 and CN2 correctly on the heater control board.
Check the value of resistance about connector on the heater control
board by using circuit tester. Check whether the value is between 78
and 106 Ω or not for each 1 to 5 pin, 1 to 7 pin and 1 to 9 pin. If it is
between 78 to 106 Ω, the heater control board has a problem. Follow
[Check if the heater control board is broken] below. If the value of
resistance is 0 or infinity, replace the coil in the dryer. 1 to 5 pin for the
upper side, 1 to 7 pin for the middle and 1 to 9 pin for the down side of
