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", but it is low enough to require HIGH fan speed. See the "safety thermal switch" here:

With the fan assembly dismounted from the Condenser Coil Assembly, 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 higher 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 the heater cuts

Any thoughts?

The manual states "klaxton." But, I am sure that the manual was originally
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 you discharge
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 Heater.

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 minutes,
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 internal safety
klaxon cuts the element off to prevent overheating." I assume that by
"safety klaxon" the manual is referring to a thermostatic switch which
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.
