Force 10 Cooker

[Sirius]

The oven valve of my old Force 10 3 burners is no longer working.
After contacting Force 10, I have been told that the issue is probably the safety bypass and more precisely the solenoid which is inside.
The problem is that this type of solenoid has been discontinued in 2000 and there is no replacement available.
Is anybody has an old Force 10 cooker or can tell me where I could find spare parts.
Many thanks.
