hi all, got a call to this cooker today. main oven fan not working. didnt take cooker out to check fan 😳 just presumed it would be the fan motor ❓ anyhow, while looking for a fan, i came across a part called a “fan failure switch” cost £45. so does anybody have any idea what this switch is? where is it? and is it likely to be this that has stopped the fan from working ❓
