Troubleshooting
your electrical system
Air conditioning quits?
Oftentimes, a blown fuse can be the cause of an air conditioning unit not
functioning. Check the outdoor air conditioning disconnect to be sure it
is in the ON position. Then, check your load center for a tripped circuit
breaker. Make sure no one is working on the electrical system, then
rmly move the tripped handle to the OFF position and then back to
the ON position.
Circuit breaker tripped?
Usually a circuit breaker trips because it detected a problem. So before
resetting the breaker, look for any obvious reasons for the tripping, such
as an overload or short circuit caused by damaged appliance wiring. If
none are obvious, reset the breaker. Do not repeatedly reset the breaker
without resolving the cause of the tripping. You may have overloaded
circuits or a problem in the permanent wiring, appliances, or power cords.
If a problem persists after following these basic maintenance
and troubleshooting tips, consult your electrical contractor or
professional for additional assistance.
Electrical system general maintenance tips:
• Test your GFI receptacles, GFI circuit breakers, and AFI breakers
once a month (See Pages 4 and 5).
• Visually inspect surge arresters or protectors periodically and after
major storms (See section on surge protection on Pages 6 and 7).
• Even if your smoke detector is hard-wired to your load center,
you should push the test button weekly and replace the backup
batteries annually. Consult your smoke detector manual
for directions.
• Avoid pushing furniture against or placing on electrical cords. This
can damage the cords and become a potential hazardous condition
for arcing faults.
