When you exchange the fan and doesn`t reset the counter the fan should work anyway, just the alarm A30042 is still being displayed. So if the fan is not running I would recommend to check if the fan is properly connected and the fan supply voltage is available. There is a FAQ available regarding handling alarm A30042 https://support.industry.siemens.com/cs/ww/de/view/109480518/en?dl=en
