I need the service manual for a Whirlpool electric oven model # WFE381LVS. I have a customer who has a Whirlpool electric stove model # WFE381LVS with ceramic cooktop. The surface burners work but the oven doesn't. The Bake and Broil does not come on. Elements tested ok and the touchpad seems to work because it will let me change temp settings and it will display what temperature I punch in but oven does not come on at all. The light works and the Convection fan will come on but no heating at all.
