Recently there have been issues reported after customers had a Smart Meter installed by Commonwealth Edison. These issues may be related to the age of your electrical service. I urge all residents to contact ComEd for any temporary loss of service, lights flashing, loss of one leg of service (phase), smell of wires burning or buzzing noises around your exterior service meter. Also if you have an older home or electric service you may benefit from having an electrician check the connections in your service boxes. Any loose connection can lead to arcing which is a fire hazard.
Bathroom Exhaust Fan Warning
The reports of attic fires caused by bathroom vent fans seems to be increasing. Moisture/steam causes hair, fuzz and dirt to collect around the fan and motor assembly which in time can cause the motor to overheat. The fan has a built in circuit breaker which should trip when overheating occurs. This does fail.
I recommend that your bathroom vent fan be placed on a timer switch so that this prevents the fan from being left on. Timer switches can be purchased at any home improvement or hardware store. These switches should be installed by a licensed electrician.
