Gas flame not high

[steq184]

I have a Leisure Bistro 55 cooker, about 10 years old, the 4 hob rings and the grill are working perectly.
My problem is that no matter what gas mark i select the flame stays the same very low flame in the oven.
I have been told it could be the thermostat or the Flame Supervision Device (FSD)
I was under the impression that the FSD actually shut off the gas if the flame goes out.......but as the flame is lit..although very low could this be the problem?
Any help greatly appreciated.

Check the thermostat phial is in the correct position, if it is you really need a gas safe engineer to have a look at it for you

90% of the time this problem is the FSD,not all FSDs shut off the supply,most reduce it to a small bypass rate and when they fail it stays at the low rate.

You need a Gas safe Engineer with cooker qualifications.
