Customer Questions and Answers for Dryer Main Control Board by Lg

Hello Jerry, thank you for contacting AppliancePartsPros.com
The first thing to look at is whether the compressor and condenser fan are running. If they are then you would check the evaporator frost pattern. If there is no frost forming on the evaporator with the compressor and condenser running then you likely have a sealed system issue which will need to be addressed by a licensed and certified appliance sealed system repair company.
