WE have a new Waeco Coolmatic icebox conversion unit that we installed
earlier this year. This is the unit:

unit uses the Danfoss BD35F compressor & controls.

Well, that's funny. (Funny peculiar, that is, not funny ha ha.)

Our unit, a 12 volt keel cooled Danfoss, acted up in much the same manner
last weekend. For no good reason it started pulling only 2 amps where it
normally draws about 4.2. It does not switch to AC.. It was running and the
evaporator was cool to the touch but not cold and definitely not frosted. We
did have a low voltage situation when the battery dropped to 10.9. That's low
enough so the voltage at the machine is too low to start. We remedied the
battery problem and full charged the batteries but the unit continued to draw
only 2 amps with almost no cooling. I tried disconnecting and reconnecting
everything and decided it needed to be recharged. On that, we went to bed (on
the hook). When we got upo the next morning the unit was running normally and
making ice like mad. It still is, now on shore power (though the unit always
runs off the batteries.

I asked the vendor from whom I bought it what was going on. Best he could
come up with was that there had been a low battery situation and the
controller freaked out and took some time to stabilize. I have heard that
those solid state controllers can get freaky but this was the first time it
happened to us in five years and also th first time we had such a low battery
condition for several hours. (We just had a new battery installed and
somebody forgot to attach one of the red cables. It wasn't on line.)
