Customer Questions and Answers for Dryer Main Control Board by Lg

Steve, if the blower thermistor 6323EL2001B measures 10O of resistance, the heater relays would be tested. If the top panel of the dryer is removed, the main control EBR76210903 relays can be accessed for testing. One of the heater relays will have a black wire and a yellow wire which will be used for testing. With a meter probe at each wire as they are installed on the relay, the dryer would need to be started while set to high heat. If the voltage reads 0VAC, this would indicate a failure in the motor 4681EL1008A. If the voltage reads 240VAC, this would indicate a failure in the main control.
