Lately
we've been getting frantic calls from clients
starting with the words, "Help! The organ
won't turn on!!" They continue, "When
we turn the switch on nothing happens!"
The call is usually made by the church secretary
who is trying to decipher what the organist
has written. Nothing for us to do but schedule
a service call.
To
most, organs are sort of like cars. You get
in, turn the key and the cars starts. Why?
Who knows? Its the same with organs. The organist
sits at the console, turns on the switch and,
magically, the organ comes on. Why?
Well, that's the whole point of this article.
I am going to explain what happens when you
turn on the organ. I'll leave it to your mechanic
to explain how your car starts.
The
switch on the console acts almost like a water
valve. When the switch is off its like having
the valve shut. No water will flow. When the
switch is on its like having the valve open.
Water will flow. Electricity can be compared
to water because, like water, it flows from
it's higher state (positive) to it's lower
state (negative) just as water flows downhill.
So, when the switch at the console is turned
on, electricity flows through the switch to
the blower motor. The flow of electric current
through the motor causes it to turn. The motion
is then transferred to the blower. The rotary
motion of the blower produces the wind pressure
needed to operate the organ.
This
seems simple enough, right? What could possibly
go wrong and cause the blower not to start?
Well, remember last summer when you plugged
the air conditioner into the same outlet as
the refrigerator? (Hey, I've done it before!)
What happened? The air conditioner and fridge
ran for a few minutes but then *poof* both
appliances shut off. Why? Sure, a fuse had
blown! The A/C and the fridge were drawing
too much current for the circuit to handle
and the fuse, like a safety valve, blew and
shut off the power before the wiring over-heated,
possibly causing a fire.
Fuses
are very important to the safety of any electrical
circuit. In some cases, they protect expensive
components from being destroyed (computers,
high-tech. devices). In others they protect
against short circuits which may cause someone
to receive a shock (home appliances). And,
as I've already mentioned, they protect against
fire. The blower circuit on your organ, in
accordance with electrical codes, utilizes
either fuses (older organs) or circuit breakers
(newer organs) or both to protect you and
the church building in the event of a short
circuit.
I'll
bet you can guess what I'm going to say next.
If the blower won't start, the first thing
to check is the fuse or circuit breaker. Where
do you find these? Well, a good rule of thumb
is to ask your sexton or maintenance person.
Without question, the sexton is the person
most familiar with the church building and
can direct you to the fuse or circuit breaker
panel with astonishing ease. If you're really
nice to them, they may even change the fuse
or reset the breaker for you. If, however,
you cannot locate the sexton you can go in
search of the panel yourself. The basement
is a good place to start your search. If you've
ever changed a fuse in your own home, you
should be able to locate the panel. Once you
have found it, open the cover and look on
the inside of it. You will see a numbered
listing of circuits that each fuse, or breaker
controls. Look for the one marked ORGAN or
ORGAN BLOWER. Once you have located the fuse
replace it with a new one of the same amp
rating. For example: if the fuse is marked
20A, it is a twenty amp fuse. You must replace
it with another twenty amp fuse. This is very
important for the operation of the equipment
and your own safety. If you have circuit breakers
you will need to reset the breaker. If, after
you have done all this, the organ still won't
come on, or continues to blow the fuse or
trip the breaker, you should promptly give
us, at Patrick J. Murphy & Associates,
Inc., a call. We will gladly schedule a service
call as soon as possible.
I
hope this article has been informative and
will help you get the organ running if you
sit down to play for Sunday service and the
darned thing just won't come on!
