Re: [Amel] Climma Heating

1 - after some time (years)_the thermal switch failed_ (low cost
switch) and for the aft cabin it is the third replacement !!
2 - the capacitors value after some time decrease an the fan can stop
and in the low position the thermal protection can operate (or not).

For information on CottonBay we have the old and the new model and I put
the same components on both (actualy I replace both parts every two
years and check capacitors)
switch that I use :
thermal protection :

If it's can help any you I can send this parts to you

Thank you for your participation on this posting, the previous
information that you posted, your photographs, and the temperature
range of the thermal switch and fuse. From my experience with the
switch, I assume that the temperature ranges you have are for the
temperature of the actual thermal switch and the actual fuse.

The Climma distributor in the US, Amel SAV and the Amel Manual, the
Climma printed information, the Climma Operation Manual and also other
Amel owners state that the fan should be on HIGH when operating the
Heater. For what reason did yo have to replace the heating coil
assembly including the thermal switch? Could it have been because you
did not operate the fan on HIGH?

For your information on Cottonbay we use all the 3 heating positions
witch 3 fans position and it works well.
In the Clima heating box there are two things
1- thermal switch that regulate the air temperature in this box at
approximatively 60°C
2- an thermal fuse (120°C) that protect the boat for fire risk if the
thermal switch failed

Yes, the fan needs to be set to HIGH when in the heat mode. My point
was that the fan was NOT running at HIGH speed when set to HIGH
because the fan speed capacitors (CM, C1 & C2) were not functioning
properly and needed to be replaced.

Because the fan was not running at HIGH speed (when set to HIGH), the
thermal safety switch was cutting OFF the current to the electric
heating coils.

Hi according to the heater manual the electric heater fan ALWAYS
needs to be on high. To keep it from turning off.

There is a small "safety thermal switch" on the electric heating
coil assembly. This switch opens as the temperature of the switch
rises. And, it does not take much of an increase...for instance at
Medium fan speed that switch will open and cut off current to the
heating coils because the switch temperature rises above range. I do
not know the temp specs and range of this "safety thermal switch",
it is low enough to require HIGH fan speed. See the "safety thermal
switch" here:


With the fan assembly dismounted from the Condenser Coil
I energized the heating...The fan started turning, I saw the "safety
thermal switch" close and within seconds the switch opened because of
zero air flow...very sensitive. Also, if you notice my photo, the
switch is conducive to corrosion.

This safety thermal switch is only in the Heating circuit and is
not connected to the A/C circuit.

To answer your question I believe that the one or more of the 3
420-470 volt 2uF polypropylene capacitors has deteriorated and out of
spec. These capacitors control the fan speed. If you replace them I
think you will find what I experienced: High speed will be much
than it was before you replace them. I believe that I simply did not
notice that the fan had slowed because the capacitors deteriorated
slowly over time.

Hope this helps.

I am just wondering why the A/C works fine on high speed but
heater cuts

Any thoughts?

The manual states "klaxton." But, I am sure that the manual was
written in some other language and translated to English. The
"klaxton" is
definitely a thermo-switch that opens at a certain temperature.
I uploaded a
photo of it at:

Hi Bill by the sound of it test the condensers but be sure
each one as you test it. You will need a multi meter with that
feature. You
can buy replacements from most electronic stores.

I am experiencing a problem with the aft cabin Climma

It will turn ON and after about 20 seconds the heating
element will turn
ON and the unit will pull about 5-6 amps. It will run for 1
to 2
then the heating element will turn off and the amp usage drops
to around 1

I read in the Climma Manual the following: "If there is a
failure of the
fan or the air circulation is clogged or obstructed, an
klaxon cuts the element off to prevent overheating." I assume
that by
"safety klaxon" the manual is referring to a thermostatic
disables the heating cycle as a safety measure.

Can anyone give me some additional information regarding
this "safety
klaxon"/thermostatic switch. My questions are: Where is it
located? Any
photos? Have you replaced it? Where did you source the part,
etc., etc.
