Belling range cooker – grill regulator 444447034

Hi,

I wonder if anybody can just confirm for me which regulator switch I need for a belling range cooker 444447034. I need the dual grill regulator. I haven’t seen the machine yet but the customer told me part of the grill tripped and now it stays on constantly unless switched off at the wall. I can’t get a blow up of the machine.
I can see just one energy reg listed, BEL082590900 but just wondered if this was correct and whether it’s just a straight swap or if I need a diagram to swap from one make to another.

Any help as usual is very appreciated.

Cheers

Nick
