This oven flame failure device is also commonly referred to as a FFD (flame failure device). This is a high quality alternative spare part that is compatible with Parkinson Cowan cookers, but primarily the Sonata and 50GL cookers that they manufacture. This FFD is designed to cut off the gas supply in your cooker if it detects that the cooker flame has been extinguished for any reason.]
Please check the model number of your cooker carefully to ensure that it is compatible with this spare part. You can do this by returning to the Cooker Spare Parts homepage and entering both the manufacturer and model number of your appliance.
