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

Good morning Eric,

I am afraid the continuity feel over my skill level at the moment…

Going to contact Titan Marine and Rob Marine both in Saint Maarten recommended by Coastal Climate Control, then likely will sail back to Saint Maarten.

Hopefully as Bill mentioned, the compressor can be changed…

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!

Sincerely Alexandre

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.

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
think Eric is right and I think
that the first
thing I
would
do is
replace the two capacitors
I
mentioned earlier.

I run the


forward air conditioning without
problem.



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.

Eric

Good
morning
John, Mark,
Eric and
Francisco and thank you for

your replies,


Based on what
you
wrote, I suspect a short and a
dead


compressor…
Going to test the Capacitors,
but how to
“discharge
them”
prior
to
testing?




Eric, I
did
not
really
understand
the:
“if
the AC switch is off
at the
thermostat
does it still trip the


breaker?”
Thanks in
advance,
sincerely,
Alexandre

if the AC

does it
still


trip
the
breaker?

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.
