Anyone help with a diagram for Ignis (wpl) Oven / model AKL905/1X
S/N 854190515511
Oven is 5/6 years old & has always overheated.
Client called Ignis in guarantee but engineer found no fault!
The lower element is not switching off even when stat turned off.
The temp light doesn’t switch off either.
someones dropped a wire at the factory i guess (Friday night)
Help.
