Hi, my AEG 41056vi-mn oven is working properly except: when using the oven at a relatively high temperature, after heating for a while it just shuts down for a few minutes (10-20), the light stays on though. It then restarts by itself and all go well. However, this behavior is new and its frequency increases and the temperature drop will ruin some food recipes. So which component is most likely broken? In case it is the overheat protection thermostat, do you have a video showing where it is (like that excellent demo for the main thermostat)? Thanks,
