Jenn-Air W188W Timer Repair

Our Jenn Air W132B serial # 23826092WK burned out the bake element last week. We purchased a new bake element and had an appliance repairman install the new element. The element failed to come on, even though the broiler works, the clock works, the controls to turn the oven off and on work - but no power seems to be getting to the bake element. The repairman says we need a new "power source" for the bake element - it probably "burned out" when the bake element "died". We spoke to Whirlpool customer service - they tell us the power control for the bake element is "likely" housed in the clock in this model. we would like to purchase a new part for this oven, and have it professionally installed. we are uncertain whether purchasing part # AP 4397494 from Appliance Parts which is labeld as "electronic control" will solve our problem. The part costs $217.00 and we hesitate to purchase it unless it will solve the problem of getting power to the new bake element. Your good counsel on this rep

I received an old Jenn-Air wall oven from a customer and would like to give it to my son-in-law, but it has problems and I cannot find a wiring diagram. Any help appreciated.

My Jenn-Air W188W wall oven control panel has stopped working. It is either the control board (202801A is the original number but now is called a PS119188) or the Glass front panel (PS505758) which has what must be capacitive switches for buttons. How can I get this replaced or repaired?
