well you need to message the shop. when I research your original number I get a different regulator so you need to give them the full model of your cooker and the old regulator number to check if its compatible
also what is the regulator controlling ? and is it single circuit or dual ( dual circuit is where you can turn the regulator left or right on say a grill. turn it one way and half the grill comes on but turn it the other all the grill comes on )
