Hi, I replaced my old light switch to the smart light switch today. After the job is done it worked perfectly until the new light switch sparked when one of the cable tightening screws touched the metal housing and circuit breaker tripped.
I lifted up the circuit breaker, all lights come back on all the rooms except the one I caused a pop. I tested the wires with the mains test screwdriver, at first it seems to be fine but later I observed no power on live cable. I tried the old light switch after resetting the RTC I don't know what I have done but the live cable becomes active again.
I tried both switches back and forward a few times as well as turning the circuit breakers on and of randomly and I can see that the live cable is sometimes active and sometimes not, the old switch works fine when the cable becomes alive but the switch caused a pop not working at all.
I suspect I fried the new light switch which I don't care but I have no permanent power on the light switch cables where I caused the pop. ( All other light switches connected to same circuit breaker works fine )
I tried turning on and off all the circuit breakers ( RTC reset ) sometimes and somehow I managed the live cable becomes active but only intermittently. I wonder if there is anything I can try before I call an electrician? any advice will be greatly appreciated. Thanks in advance.
