I have an LG gas dryer DLG2702V about 12 years old. Nothing happens with I press the start button, no displays light up. When I open the door, the inside light turns on and turns off when I close the door. That tells me the door switch is working. Hopefully someone can give me some suggestions on what to check. Maybe someone has access to a troubleshooting flow chart or electrical schematic. Any suggestions is greatly appreciated. Being a senior citizen, I'm not as flexible as I used to me, lol.
