unless the stats are provided by a reconised supplier its not worth the risk of fitting stat that may or no be to spec
also there are 2 heaters fitted to this model dependant on serial no, one of them has a non gen equivalent for about £20 so not worth the risk for that price
what you have to think these days is if the tumble dryer fails and causes damage any work you do would come under the spotlight. If you have fitted correct part then they cant blame you
