Actually the condenser tubing was icing as well...a lot...prior to the freon addition.

Also the compressor part of the condenser was running too hot to touch prior to additional freon. All of that fixed with more freon.... but now, get immediate LO PS error in heat mode. (SXII control)
FWIW, the boat has 5 Cruisair condensers. One other one is now giving LO PS error as well but that one does so in both cold and heat mode. The other 3 units work fine in both modes.
I have had HI
PS errors in the past but they were always due to clogged raw water intake strainer and effected all 5 units. Strainer looks pretty clear now.
