The oven works but the gas stays at one level. Heat can not be increased ?

your fsd valve will be faulty .
there is a probe that comes off the valve that senses the low flame in the oven once this probe has warmed up it opens the valve to full flow.
the only option is to get a new fsd valve .and a gas qualified engineer to fit it.so you dont blow yourself up
