Title: Buzzing photocell
Post by: Mercuryvapor123 on September 03, 2015, 03:57:25 PM

I have a couple of vintage NOS American Electric photocontrols  and they still buzz after shutting the lamp off what causes this and can I fix it??

The relay is buzzing. Some PCs do that; not sure why. Shouldn't be an issue. As long as the contacts don't arc (lamp flickers/dims and PC buzzes/chattered violently) before the PC shuts the light off then it's probably fine.
