Smeg SE375MFX5 Oven – faulty selector?

Hi there,

My oven doesn’t heat up nor do I get the thermostat to light up but the secondary fan does comes on.

When I turn the selector I can sometimes get the fan and neon to start / light up but the neon and interior light flickers and the selector does seem stiff between “11 and 1 o’clock” positions.

I tested the element and get 30 and 50ohms for the inner and outer element and the thermostat makes a circuit when turned.

I assume it’s therefore the selector especially as it seems there’s a blemish on one of the contacts (melted plastic / food?).

Do you agree and does anyone know the part number?

Thanks
