Good morning Ian,

Yes the Calpeda Water pump works as the other air conditioning units work,
and I believe this is a loop from 1 unit to another then out at the bow on
the port side.

Yes the main boat breaker and the shore power trip instantly when
electricity go to the unit. If I disconnect the harness going to the
compressor, it does not trip the power.

Yes the other air conditioning work.

I am very reluctant using the generator to try to run the faulty air
conditioning as I don’t want to risk another control board.

I already testes and changed the capacitors…

I am afraid it is a short in the compressor…

Thanks again for your help…
In a couple of weeks, likely to go back to Sint Maarten and have a proper
Climma tech doing the trouble shooting…

Sincerely, Alexandre

Hi Alexandre,
I take it that you have checked the obvious? Does the
Klima a/c
water pump send cooling water through to the outlet on
the forward
port side of the hull? If the pump motor is not
running then the
CB will trip after a few seconds. I recently went
though this. At
first I thought the motor/pump had seized up and
needed the turn
with screwdriver treatment. But in my case it was the
10uF run
capacitor that had fallen to 6.37 uF . Changing this
for a new one
restored normal working.
If the breaker trips immediately then it is likely to
be
something else. I take it that the other a/c units
work normally?
If not, it may be associated with the cooling motor.
Try tripping
the Eau de Mer breaker in the engine room. Then start
the genset
and select the suspect a/c unit to on. If the breaker
trips after
about 20 seconds or so, then it is likely to be a
cooling motor
fault. Maybe the run capacitor is short circuit?
Disconnect the
two wires that disappear into the motor itself.
Measure the
resistance. It should be around 38 ohms. If your test
meter
measures capacitance, check the actual capacitance of
the
capacitor under the lid. You must disconnect it first.
If it is
not 10 uF then best to change it.
Apologies if you have already been through this, but
I have only
just seen the thread.
Good luck

Going to contact Titan Marine and Rob Marine

Hopefully as Bill mentioned, the compressor

I have not tried to tap the compressor with a
soft mallet,
as when it is connected it trips the power.
(If I
disconnect its harness then the power does not
trip).



Have a great trip!

Hi Alexandre,

Continuity means that if you are using a

multimeter set to ohms. If you touch the
two leads

together you read 0 that means there is a very
good

connection between the leads that is
continuity. If you

have the compressor disconnected and touch
one lead to
one

of the two power wires and the case of the
compressor on a

shiny area and the meter reads 0 you have a
short in the

compressor.



Climate control only sells parts to the two
operations

in St Maarten.The Climma company near the
bridge

perma frost has an extremely bad reputation
and I have had

experience with them. Enertech also wanted to
build me a

new evaporator for one of my freezers for
$600- years ago

and the evaporator cost me $150 from Climate
control. You

might ask at Budget marine or Island water
world for a

recommendation.



The dometic air conditioner is almost a do it
yourself

installation without almost any modifications
to the

system.

If the compressor is shorted it is more
economical to

replace the whole unit as it is old and
something else
might

go bad.

Did you try tapping the compressor with a soft
mallet

and then seeing if it will start.

Good luck.

Good afternoon Eric,


I checked the small capacitors as well
as the large ones.

I am not sure what means “measure
the

continuity to the

compressor case”.


When I plug the air conditioning: it
trips the power.

If I disconnect the
wires in the harness going to the

compressor, then it doesn’t trip.



So by “having a bad compressor”
does it means that I need a new

one?
Or can it be rebuilt?

According to Climate Control, they are
2

Climma Marine person in

Sint Maarten,
I will contact them, then likely go back
there.

Thanks for the info
on the Dometic 10. Will it also power the

Calpeda cooling pump? Or does it
required

modifications…

Sincerely, Alexandre

Alexandre,
I am leaving the first bridge
tomorrow.

I would check the 3 small capacitors
that

run the

fan.
I
guess you checked the 2 big ones that work
with the

compressor.
did you measure the continuity to the
compressor case

to the power leads of
the compressor?



I think you have a bad compressor
and bad fan

capacitors--remember there
is a time delay.

If you bring a AC tech
on board I think he will find

the
same. The other very obscure possibility is
that the

compressor is out of gas. However that
is

something that we

can not do. The
compressor gas is measured in ounces.



Fair Winds,
Eric

Good morning Eric,
Since you
are

leaving in a little bit, making it
short:

Here is what I did:
I completely removed the unit (I
will

make an illustration later
on of the
removal process).

I connected the air conditioning
unit

in

the cockpit to a shore
power (this way
it won’t trip my boat all the time).

Here is what I find out:
When I
connect the harness going to the

compressor, the power

trips
right

away.
So I disconnected the harness

going to
the compressor and it did

not
trip.
In one of
your email, you

mention if there is a
short in the

compressor, then it is dead. Correct? Or is
there other

test

to do?


Also,
I did another test (not connecting

the
compressor harness)

but
connecting

the harness to the fan (and
control), the power

did not trip,
but the fan was not turning

(even
thought I was

measuring
electricity at the fan plug).
So looks
to me
the fan is also dead…

Some pictures of the above tests:

Thanks again,
sincerely, Alexandre

Eric,
I would like to test
those capacitors...I think
that

they

might


charge when

power
goes to the control
unit. Of
course
his problem could be

anything,but I had his exact
problem and

changing out the


Compressor
RUN
Capacitor
(40uf) solved the
issue.

I run the

As Eric
ask, I

switch on the Aft Air
Conditioning
with the
switch in
neutral position (neither cold
not

hot)

and


right away

the Ground Fault Interrupt
(GFI) breaker trip

(as well


as

the
marina).

What

does that tell you?

Alexandre,

there is

a switch and
thermostat by
each AC unit. when
the
switch is in neutral
position does
the
breaker still
trip?

if not does it trip
when the switch

is in
the heat
position?
To
discharge
the

capacitor take a wire

with
insulated
alligator clips

put
one clip on the body
of the pump or
case
and the other clip to a lug
of

the

capacitor.

John, Mark,
Eric and

Francisco and thank you for
your replies,
Based on what

compressor…
Going to test the Capacitors,

“discharge

prior
to
testing?
Eric, I

did

really
understand
the:

“if

does it still trip the

if the AC

the

The
breaker on the AC panel side
is a
quick
blow

circuit breaker,
If
there is

a short
it will
trip

before the
diruptor.
If the AC is on at the
thermostat and
the circuit still trips the
breaker,
Check the

continuity of the compressor
to
ground. If

there is a short to
ground
the
compressor is
dead.

Good

afternoon,
Today, I hear
the
fuse of the 220 Volt
Panel

tripping
(the
one
behind
the
panel).

I
found out
the
fuse of
the

marina also

trip.
After running
tests,
the cause is the
Aft

Cabin
Air

Conditioning
(which I
have been
using non

stop for 9
days).
Running
the salon does
not trip anything.
What could
be the
cause?

How to
diagnostic
and
solve the issue?

Did I use too much
the
air conditioning?
How come the
Diruptor
did not
trip, but the
220 Volt Panel did?
How come I trip
the

marina
fuse?
Thanks in
advance.
