The cruising season is drawing to a close down here on the Mexican Riviera and we're getting ready to head
home. (in case you're curious, there are absolutely no signs of the Flu down here.) But before we go, I'm trying to solve a problem that cropped up with our AC last night.
We have two 16,000 BTU Cruisair
split units with SMX II controllers on our Valiant 50, Raptor Dance. Last night the Port unit came up with the following problem. When the unit is in AC mode (Cooling), the water
pump starts as expected and fan comes up in speed. Both as they should. However the compressor
does not start (no current
draw). There are no other symptoms and no error codes. It's as if everything is fine - except no compressor
Since we have two units, I swapped the two controllers (the SMX units) and the problem remained with the specific unit - it did not follow the controller. So the controller appears fine.
Also, a reset of the unit electronics
did not change a thing.
The symptom are not those of a frozen compressor - which is large current
draw that pops the breaker.
So before I go diving
into the transom (a time consuming chore as the compressor and control box
are behind the propane
lockers which I have to remove to get there). Does anybody have any other ideas?
Fortunately, there is a good local service
guy - unfortunately, he can't fit us in until after we're scheduled to head
