Electrical Repairs

Light fixtures not
working: If the fixture is
incandescent, a single lamp or chandelier,
shut power off. Replace the light bulb
and try again. If only one lamp is out
on a chandelier, the problem is in the
fixture. Call for service and send us
a digital picture so we can bring the right
socket. If a single lamp incandescent
fixture is out, then it is the socket, the
fixture or power to the fixture. If
you are a weekend warrior and want to save
some money, pull the fixture and check for
power. If there is power, then the
fixture is bad; replace it. If there
is no power, give us a call, there is a
power issue. Always shut power off.
Do not work on energized equipment.
-
Fluorescent
fixture out. Shut power off,
try replacing the lamp. Turn the power
back on; if the fixture does not work, it
could be a ballast or power problem.
You must be very careful. Fluorescent
fixtures have ballasts that can boost the
voltage as high as 600 volts. You must
turn the power off, otherwise, you could get
electrocuted or severely hurt.
-
Power out?
Check your circuit breakers. If the
breakers are not labeled, look for a breaker
that looks tripped - different, a little
off. Try to turn it off. You
will have to shut it hard off, then back on.
This will reset the power. If this
does not work, give us a call for a
serviceman.
-
Air conditioning
not working? Try resetting
the circuit breaker (see power out – breaker
resetting instructions). If the
breaker is not tripped, then you may have a
blown fuse. Turn your power off to the
air conditioner. It would be a 220
breaker. If you cannot find your
breaker, do not try to replace the fuse
without shutting the breaker off. Give
us a call if you have no power. If you
hear a loud buzzing in your compressor (the
unit outdoors) or it smells burned at the
compressor, then the unit itself is damaged.
Call an HVAC technician.
-
Electrical
appliances not working –
refrigerator, trash compactor, television,
stove, dishwasher, computer, etc. Try
resetting your breaker first. (see
power out – breaker resetting instructions).
If this does not fix the problem, and you do
not smell a burned smell at the appliance,
chances are the problem is electrical.
Try resetting the breaker and if no success,
give us a call for a serviceman.
-
Power at one
outlet is off. My power out
is out at only one receptacle in a bedroom.
Check to see if this is a switched outlet.
Often in tract or custom homes, overhead
lights are not installed and switched
receptacles were used instead.
-
Power is out to
3-4 receptacles in one room, two bedrooms
are next to each other. If
your home is circa 1970-1990, stablock, or
quick wire receptacles that daisy chain in a
parallel series manner may be the problem.
If one of these stab type spring friction
connected receptacles loosens, a whole area
of a circuit may go out including indoor
lights and outdoor lights, depending on
where this receptacle is in the circuit.
The electrical code for San Diego allows up
to 15 current consuming devices on a
lighting circuit assuming they are low
power, 1 ½ amps or 180 watts each. If
you have 10 or 12 plugs out and no breaker
is tripped, you probably have a stablock
feed through problem. This is a common
problem in older homes. Call us for a
serviceman, as this problem cannot be self
repaired.
-
Power out to half
your house, and all 220s are out.
This would normally mean that your main
breaker has tripped from age or overload.
To reset your main, shut all your other
breakers off first. The main breaker
will be a double breaker marked “main” or
“Service Disconnect”. It normally is a
100-125 on an older home or town home that
has your meter at the house. For
larger homes or homes 1980 or later, the
electric services are more likely 200 amps.
Do not try resetting the main breaker with
any loads on. This can be unsafe and
cause power surges and damage electronics,
burn up computers, modems and create many
additional problems. If you find the
main breaker is not tripped, then call SDG&E
and see if you have a power outage in your
neighborhood. See if your neighbors’
lights are out. If not, you may have a
localized power issue that is utility
related in a new Smart meter or a problem
with the meter socket. SDG&E will come
out at no charge and confirm it is not in
their utility system. If it is, it
saves you a service call; if not, then give
us a call and we can make a repair.
