Electrical Question from Ken about Electrical Device Problems
Background: Ken, a Student from Dallas, Texas
[ad#block]Question: I have a vent hood over my stove but the fan doesn’t work, if I leave it on and it doesn’t work what can happen? Also I hear a hissing noise coming from my light switch like a low voltage tazer, what could this be. Furthermore, the lights in my kitchen dims and brightens and sometimes only portions of the lights come on, what could this be? But most importantly I will like to know what happen when you leave appliances that don’t work running on power?

Dave’s Reply:
Thanks for your electrical question Ken.
Disconnect any electrical device that does not work to avoid overheating and a possible fire hazard.
The hissing that you hear from the light switch may be caused by the contacts breaking down. I suggest that the switch be replaced.
The problem you are having with the kitchen lights is most likely due to a faulty connection or splice within the electrical circuit. This is discovered using troubleshooting techniques as described in the Electrical Troubleshooting ares of the website.
