The unit is easy to replace but is there a way to tell if it is the light unit or the power supply unit? I have and can not get any wiring diagram to see what the voltage is supposed to be.
Every time I have seen this problem, it has been a bad display assembly. These are fairly easy to change yourself, but the part is kind of expensive, I think in the $150-$200 range. Hope this helps!
I talked to Jenn Air and they did state a reason that seems reasonable. It is not the display assembley that is the problem but the design. The HEAT causes the display assembley to malfunction. Jenn-Air has added a cooling fan between the baking area and the display assembley in the newer models. You may have to keep replacing the display assembley about every two years if use the oven a lot in the older models. Yuck!
