Replacing
switches.
Turn off the power. Some
switches can have multiple circuits within the box!
Single pole.
If there is only one switch controlling a
light, it is considered a single pole. When replacing a single pole
switch or dimmer, there are only 2 screw contacts on the switch or
dimmer (excluding the ground screw). Before removing the switch, note
what wires are located on the screws. Some switches may have
several wires going to one screw terminal. Remove the existing
switch and install the new device. It does not matter which screw the
wires go to (unless its a lighted switch or multiple ganged switch).
Three way.
If there are 2 switches controlling a light, it
is considered a 3-way. When replacing a 3-way switch or dimmer, there
are 3 screw contacts on the switch (excluding the ground screw).
Before removing the switch, look at it. Two contacts (screws) are the
same color and the other is an odd color. The odd color screw will
usually have a mark to designate it as the odd terminal. The wire
that comes off of the odd color screw on the original switch, needs
to be connected to the odd color screw of the new switch. Connect the
remaining 2 wires to the other 2 contacts. (Trouble

Trouble
shooting 3-way switches.
Continue only if you are qualified for working
with live electrical parts and are
familiar with working with testers! Read
all of the following before beginning. If an item is unfamiliar, do
not attempt to continue.

Switch
Plates.
When installing switch plates, turn the screws
so the slot runs up and down (vertical). It gives the installation a
nice professional look.
When painting switch or outlet plates, use 220
sandpaper to remove any dirt and to smooth and "deglaze"
the plate. It should have a frosty look to it. Use any normal primer
and house paint to complete the process.

Broken
lamp sockets.
If you try to remove a light bulb and the base
of the bulb breaks off and remains in the fixture socket, here are a
few suggestions for removing the light bulb base without damaging the
fixture socket.
-
Make sure the power is off. At this point, there
are exposed electrical contacts in the bulb base. It is very
difficult to tell if the power is off if the fixture is controlled by
a 3-way, timer, etc.!! Check and double check!!
- Here are 3 ways I have used
to remove a broken bulbs.
-
Use needle nose pliers. Not in the way you
might think. Do not try to grab hold of the metal lamp shell and turn
it. This usually will damage the fixture socket. Instead, close the
pliers and insert them into the socket shell. Then open them up so
they will press out on the broken shell. With sufficient opening
pressure, turn the pliers counterclockwise. This should bring the
shell out.
-
If space will not allow you to use needle nose
pliers, I have used a thinly sliced piece of wood (popcicle stick).
Shave the width of the wood down so it will snuggly fit into the lamp
shell. Turn the stick counterclockwise to remove the broken shell.
This usually only works on smaller socket shells.
-
I have also heard of using a potato. This would
probably work but I really like french fries and would hate to ruin a
good potato. I would use this method as a last resort.
-
Always check the fixture socket after removing
a stubborn lamp for damage.

Replacing
plugs on a cord.
It sound simple to replace an old plug on a
lamp cord. I'm sure thousands of plugs are replaced each year without
incident. However, there is a correct way to install a plug on a cord.
-
When replacing a plug, always purchase the
correct type. There are many different types on the market. A good
rule to follow is to take the old plug with you and determine what
type of plug you have. Before you cut or remove the old plug from the
cord, be sure to identify which wires went to which terminals. This
will be very helpful when installing the new plug.
The main differences of the plugs are:
- Grounded cord with a ground prong.
- Non-polarized plug - (2
blades, both blades are the same size)
- Polarized plug - (2 or 3
blades, the grounded blade is slightly larger)
After purchasing the plug, make certain you
install it on the cord correctly.
-
If the plug you are replacing was a 2 blade,
non-polarized plug, it will not matter which wire goes to which blade
or screw of the plug.
-
If the plug you are replacing was a 3 blade,
then the grounding or green wire needs to go to the grounding prong.
This is the 1/2 circle prong. The white, or identified wire needs to
go to the slightly larger blade of the plug. The identified strand is
the grounded. If the wire is not color coded, the cord manufacture
could have identified the wire by placing ribs on the cord or a mark
of white or grey. Again, the identified strand should go to the
larger of the two blades. The last wire to connect would be the black
or "hot" wire. This should go to the smaller of the 2
straight blades.

Moisture
forming around your bath vent fan.
There could be several reasons moisture would
be on the ceiling or on your bath fan cover.
-
If you are taking steamy baths or showers, you
need to let the fan run for an extra 5 or 10 minutes after your done
with the bath or shower. The reason for this is not only to eliminate
any humidity in the air, but to clear the bath vent duct of moisture.
Water vapor can collect on the insides of the fan duct (especially
when the attic air temperature is below 35 degrees) and drip or
collect in the duct. If enough of the water vapor collects and pools,
it will leak back down into the fan unit. By running the fan an extra
length of time, this will help evaporate any moisture on the duct
walls or that may have collected in a low area of the duct.
-
Check to see if your fan has adequate
insulation covering the fan. If you take a steamy shower and the
attic area where the fan is located is colder than 35 degrees,
condensation will form on the metal shell of the fan. This is the
same phenomena that a cold glass of ice water goes through on a warm day.

Hints
on those light bulbs that are hard to remove
It seems I've had more and more customers
complain about light bulbs that seem to "stick" in the
light socket. I think there are several reasons for this.
Almost all fixture socket shells and light bulb
shells made today are made from aluminum verses brass (you can still
find brass base bulbs and brass fixture shells today, but it costs
more for the manufacture to make and the average consumer wants the
lowest cost). Because of the aluminum shells and the aluminum bases,
the two metals "fuse" together ever so slightly. This can
be better illustrated by looking at old aluminum windows and sliding
doors of the past. After time, the aluminum would eat away at itself
because it would "fuse" together and then be broken apart
when opened. With windows and doors we had a lot of leverage to break
the bond apart. When it comes to light bulbs, not much leverage
exists and usually there is not much room for your fingers in some
fixtures.
Solutions
-
Smear a light coating of Vaseline petroleum
jelly on the threads of the bulb. This will help in removing the bulb
from the socket.
- Buy bulbs that have a brass
base. Sometimes they are hard to find but if you are having trouble
with some bulbs sticking, the look will pay off.
- If at all possible, try to
avoid using the "poles" that are designed to remove and
install bulbs in high places. These poles may let the bulb become
cross threaded when installing or put un-needed pressure on the bulbs
when removing the bulbs causing them to break.
If the bulb breaks while you are attempting to
remove it, see the above "Light bulb
broken off in a light socket."
