I have issues with two light switches in my house but am not sure if I have to get an electrician in or not. I am trying not to spend any money unnecessarily but obviously want to feel safe.
- Switch by front door that turns on porch light has a small flash of blue light sometimes when you flick it, but not every time. Never got a shock and it works fine. Is this dangerous?
- Switch in DS room has suddenly become really stiff, so you have to really push it to turn it on or off. I googled it and there is conflicting advice about using WD40. Can I use that on it?
Many thanks.
