所有Parts 都有continuity 但electric control board 有燒過的sign. 电工朋友fix the connection from the board to the power plug. But still no heat. I had a technician came over ($100) to confirm the board had to be replaced but it costs total about $750 to replace the board and labor. I orginally want to buy the board $450 and install by myself but the technician told me it needs reprogram the board so I give up to repair the dryer. 其實是否真的要 reprogram the new control board ?
