Hi guys, after a bit of advice. Customer just called re this oven. The lamp had gone. The removed the old one and binned it, then a week later bought a new lamp. It’s an e14 but they are telling me that its does not fit. The whole is to big. The said the old one just screwed out but the new one won’t go in I can only guess that the threads have worn? And ideas or an Pn for the whole housing
