This is a range oven dual fuel. elec ovens and gas hobs.
The fault was no power to the left hand side oven and the separate grill above it. I found two faults. the heat fuse, which i shorted out for test purposes and a semi burnt out terminal box. I replaced the terminal box and discovered that there was still no power to the grill.
i tested and found that there was no neutral which is fed from the selector switch.
I removed the hob top but but could not work out how to remove the front facia to easily gain access to the selector switch.
any advice appreciated.
