We have a Winchester cooker and yesterday the oven decided not to reach temperature, could it be a valve?
Grill and hob work fine, oven ignites, gas is there but the flame is very small and wont turn up, stays arounf mark 2. Any help please?
I think you will find that it is the flame failure device (FFD) that has failed. These cost about £40-60, depending on where you manage to locate one, either online or at a local spare parts warehouse
