Razor only power outlet buzzing sound
Hello, this is my 1st time posting here, Ive searched and searched and could only find similar questions from people living in the UK, with slightly different issues
Here's the thing.. I live in BC (Canada), our townhouse was built in 1984, in the washroom is a razor only power outlet, it is seldom used by us, like maybe twice in the 4 months we have been here, and for less then 20 min each time, oh ya, it was my razor plugged in, but I now charge it elsewhere because the outlet constantly makes a humming noise/buzzing noise. The metal plate surrounding the plug is slightly warm to the touch, Not Hot, It does makes this noise 24/7. there is nothing else plugged in to it, there is no other switch attached to it,no light,nor fan etc I have tried pressing the test button a few times,although the test button does seem to function properly, this facilitated no changes...
thank you in advance
