my friend has just moved house and i have re-wired their cooker up but they are now complainin the light and fan does not work. its a hotpoint one? they said the removed the cable so i have put a fresh bit of 6mm in. im not 100% but there is some sort of copper link in place on the live to another terminal but not one on the neutral, maybe it was lost? or maybed there should be one there? does anyone have any idead why the light and fan would not be working?
