I picked up a GE Z-Wave smart switch and want to replace my dumb fan timer as it seems to be flakey at best.
I flipped the breaker for my bathroom circuits and pulled the fan switch out. It is nicely labelled with all 4 connections required for the GE switch (load, line, neutral and ground). But the display on the dumb switch remains on. I’m worried there is some current flowing through one of the wires. Any ideas here? With the breaker flipped I’m not sure what else to try. Is there a battery in there perhaps?
thanks in advance
