It could be the Flame Failure Device (FFD or FSD) has failed but gas normally still gets through although the oven flame won't 'flame up' fully.The fault could simply be that the ignition unit, (where the flame emerges), at the bottom of the oven needs cleaning to remove grease and debris from it. Remove it if possible to make it easier to clean thoroughly.
