I have old switches at home for the fan and lights. In short, 2 switches to control fan and lights separately.
Recently, I've been trying to add a timer switch which requires neutral and it doesn't seem to work as expected.
on left, there is black, red, and white and copper on right, there is black, white, and copper.
- Red(left) + black(right) = light on
- Black(left) + black(right) = fan on
My old switches didn't have ground connected and only had the above two connected. Copper ones and white ones were connected to each other- which I don't quite understand why.
Anyways, what I tried was - For light switch, have red(left) and black(right) connected. - For fan switch, have black(left) and black(right) as hot and load, and use white one from connected white wires as neutral.
What happened was initially, the switch seemed to work (well, at least the light indicator was on), but as soon as I touched any buttons, it died. light switch continued to work.
Was hot and load possibly flipped? I still don't quite understand why the switch behaved/died the way it did even with this assumption.
Any help here would be tremendously appreciative!!
