Hi all. I'm not an electrician and have very little experience so please bear with me. I have a recurring issue with my bathroom light. A while ago it stopped working and assuming it was the bulb I replaced it but no new bulb worked. The pull switch wiring looked intact and clean but on a hunch I cleaned the terminals on the lamp holder, as the bathroom does regularly fill up with steam and then talcum (yes I did isolate the lighting circuit beforehand) and this did the trick...for a few months. Then it started to fail again - the symptoms being that if I did a short pull on the switch it would just flash weakly and go out but if I did a long pull on the switch it would usually stay on. Now it doesn't go on at all, however long the pull is. So I want to ask whether this sounds like dirty/corroded terminals in the lamp holder again or something more serious going on? Thanks in advance.
- TL;DR
- Do lamp holder terminals often get dirty and stop lights from working?
