Electrical ? Re: pop and trip in light switch


Hi,
I am new to the chat room. I have little electrical experience, just a few switch replacements, lights, fans. My daughters' light switch (combo light & fan) just popped and then tripped the switch. Should I be able to just put in a new switch or is this potentially dangerous and should I call in an electrician? Never had an electrical pop before ........

Thanks very much

First, I'd take both appliances apart and look for a short. It sounds like a hot wire is touching ground. Wires come loose, fray through, get accidentally pinched under something, or rodents eat at them. Switches sometimes short internally, too. Good luck. j

What he said, but with the power off, it should be safe to work on. If you have any doubts, call a pro. The part that 'popped' should be easy to spot, you will see burn/flash marks. You said it was for a fan. Look in the canopy under the fan with the switches. The capacitor that gives the motor the 3 speeds is often a culprit. It is usually a square block with 3+ wires comming out of it.

I had a loose neutral wire and it blew out the switch. Getting a new one today to replace tonight.

Thanks again, much appreciated!

Loose neutrals do not cause short circuits unless they touch the hot wire.
