AEG B4101-1-M. PNC944 181 739 New fault. Oven switched itself off at end of timed cook and would not restart with usual cancellation of the timer beep. Subsequently checked thermal cutout which appears intact (have sent what a previous triggered one looks like) After having been switched off whilst checking the obvious, the oven now works again, including a 180° cook yesterday evening. But the cooling fan did not activate. So not sure what’s going on, whether it’s the fan or a thermostat somewhere.
