I have a dryer whose model number was on a sticker that has been removed. It is a kenmore gas stackable unit that is about 4 years old. There is no digital read out but there are several leds. All the leds on the right hand colulmn flash rapidly when I try to start it. What could this mean? New control board --- I removed but can't find a part number that is recognized on line or door switch?
