The heater for my lg1403rd has stopped heating up on a drying cycle . I have replaced the heater element and also tried taking the temperature sensor out of the circuit but still no heat ,the fan comes on and there are no fault codes so it seems no power is getting to the heater element from the power control board. I have checked for continuity on the power leads to the heater element The blue wire seems to go to the power control board as do the wires from the dryer control switch.and the red wire goes down behind the drum. Is there a switching component on the power board that has gone and would a new board solve the problem . Everything else works fine ,just no heat for drying
