The hob cooling fan on my AEG competence cooker took longer and longer to switch off – suspect the temperature sensor- as the cooler the kitchen it used to turn off eventually – now it’s turn off point is so low I have to turn the whole cooker off at the wall. I have found the sensor but getting further into the control panel – it is not obvious how to take the plastic front panel off after the sensor and strip have been unscrewed. ❓ any help with spares or advice apreciated.How on earth do you get a pictorial parts list ❓
