Hello I have a maytag dryer model# 641c I need a copy of a electrical wire diagram or service manual, It turns on cycles and turns off when door switch is open I have ohm'd the heater element and all t-stats still have no heat when I removed the back cover to inspect and clean out I found yellow and thick green wire laying in bottom of drum Im assuming these have something to do with it but all my exsperience is in newer appliances I havnt seen anything like these since I was a child. Any help would be greatly appreciated thanks
