Whether part of it has fallen off, the flame symbols have rubbed off, or whether it has melted, the hob control knob for Parkinson Cowan cookers is an outstanding replacement for your cooker. Despite it being referred to as a kit, you should not be put off by this, as it is extremely easy to assemble. The flame symbols allow you to easily select the temperature of your hob, putting you back in control of your cooker.
The bonus feature with this spare part is that it can control both your hob and grill, making it extremely versatile. Despite this being made for Lyric 50G models, it may still fit your cooker, so please visit the help centre to check before purchasing.
